The way they work is fairly simple, and their placement is crucial to them being efficient in their purpose. For example, the radio feeding the top antenna usually works best for communicating while the plane is still on the ground, while the one feeding the antenna on the bottom of the plane will usually work best when the plane is in the air. "No Ground Plane" antennas are also a compromise, as is the shorter length of the Phantom Elite antenna you mentioned. Your best bet would be to use those brackets with the longer Comtelco whip antenna. vagrant ker-muhj-uhn. Joined Nov 19, 2005 Messages 2,642 Location California. the ground plane of the antenna is replaced by the Partial Ground Plane. Now this structure will be designed on the HFSS Software, with the Partial ground plane values as x = 15 mm and y = 39.92 mm. Then the antenna will be applied for analysis, from which the Return loss plot, VSWR Plot and Y-Parameter plot will be studied. The structure of. Grounded Antennas: If an antenna is grounded, the earth still acts as a minor and becomes part of the radiating system. The ungrounded antenna with its image forms a dipole array, but the bottom of the grounded antenna is joined to the top of the image. The system acts as an antenna of double size. Thus, as shown in Figure 9-13a, a grounded. Ground plane width along y-axis, specified as a scalar in meters. Setting 'GroundPlaneWidth' to Inf, uses the infinite ground plane technique for antenna analysis. Example: 'GroundPlaneWidth',2.5. Data Types: double. The standard ground plane antenna consists of a vertical radiator which is insulated and centered between 4 horizontal surrounding radials which extend out from the base of the antenna. Each radial is evenly spaced (90 degrees apart from each other) around the vertical element. All antenna lengths depend on various factors. The company says the antennas have better gain and better impedance matching than some traditional antennas, can be used without a ground plane, and can be mounted inside of the aircraft structure rather than to the skin. Installation is accomplished with adhesive, and the antennas have a lifetime guarantee. One antenna type works for com, nav. The default helix antenna is end-fed. The circular ground plane is on the xy- plane. Commonly, helix antennas are used in axial mode. In this mode, the helix circumference is comparable to the operating wavelength and the helix has maximum directivity along its axis. In normal mode, the helix radius is small compared to the operating wavelength. A ground plane for a CB radio antenna is the metal surface required below the antenna. In mobile applications, the vehicle body/frame acts as the ground plane (reflective unit). The metal surface enables the signal generated when transmitting to reflect off the. Answer (1 of 7): A good example of where a ground plane would be important is on a mobile rig. Even with a good SWR, some of the reflected power is going to feed back into the rig; so by using a ground plane it acts as a sort of buffer if you like to dissipate the actual reflecting energy feedin. The default helix antenna is end-fed. The circular ground plane is on the xy- plane. Commonly, helix antennas are used in axial mode. In this mode, the helix circumference is comparable to the operating wavelength and the helix has maximum directivity along its axis. In normal mode, the helix radius is small compared to the operating wavelength. proven to yield excellent results. See Chapter 6 for more details on practical ground-plane verticals. For a vertical antenna, a la rge ground screen, either made of wire mesh or a multitude of radials, or an elevated system of ground-plane radials will reduce ground losses near the antenna . This is because. 1/4 Wave Ground Plane Antenna Calculator Ahh, the good old quarter wave ground plane! This calculator can be used to design a Quarter Wave Ground Plane antenna, with radials. The radiating element is a quarter wave (λ/4) and the radials are 12% longer. There are usually four radials, three being a minimum, but you could use up to six. An antenna so constructed is known as a GROUND-PLANE ANTENNA. Two ground-plane antennas are shown in figure 4-41, views A and B. Figure 4-41.—Ground-plane antennas. CORNER REFLECTOR When a unidirectional radiation pattern is desired, it can be obtained by the use of a corner reflector with a half-wave dipole. A CORNER-REFLECTOR ANTENNA is a. I'm planning on allotting a 40mm x 40mm ground plane underneath the patch antenna; Note that the ANT1818B00DT1516A datasheet specifies a 50mm x 50mm ground plane underneath the patch antenna. If the ground plane is larger or smaller then there will be effects on the overall performance of the antenna. You can read more in this Maxtenna. I am debating on the MaxRad 3 DB gain (no ground plane) for $40.. or the Tram 1175 with 2.4 DB gain (no ground plane) for $30. or the Browning BR-450 5.5 DB gain (ground plane type) for $27 or Tram 1177 5 DB gain (ground plane type) for $19. ... At any rate, NMO-mount mobile antennas work best with a good ground plane under them, and mounted. The antenna must have a ground plane to be efficient, and ideally the ground plane should spread out at least a quarter wavelength, or more, around the feed-point of the antenna. The size of the ground plane influences the gain, resonance frequency and impedance of the antenna.[3]. Thanks to radio amateur Dave Tadlock (KG0ZZ) for this simple, effective VHF/UHF (2m/70cm) ground plane antenna. Most of the materials can be found at the nearest hardware store or building supply outlet. The antenna is perfect for local traffic and ragchew nets, as well as portable and emergency use. Dave's explanations are clear, simple, and. W1TR 40 Meter Ground Plane. Updated 05-Dec-2005 12:53 [back to W1TR Antennas and QTH] [back to W1TR Home] The 40 meter ground plane is constructed from #12 stranded insulated wire available in most hardware stores. The feedpoint uses PVC a pipe T-section. The coax loops through the T-section to provide strain relief. The G3JVL 6 Meter ground plane vertical is a compact antenna that is ideal for portable operations. If needed, it can be disassembled into a very small bundle no longer than the longest element. 10 meter homebrew vertical antenna Homebrew a 5/8 wave ground plane antenna for 10 meter band.

I mounted the small post antenna on my belly, almost between the pedals, so it is on that thin aluminum floor. I just drilled a 1/2" hole and mounted it with a lock washer. This is an excellent ground plane, and also convenient since the short BNC cable just drops down from the panel. The Xponder checks out fine with ATC. Place the mounted antenna directly over this ground plane. This can also be done in a room or on a patio. Also, for a room; you may want to run some wire around the base board and place the mounted antenna near the corner. In all of these, and any installation, be sure the ground plane is connected to the shield of the 52 ohm coaxial. A larger ground plane results in higher accuracies. The ground plane seems to have a higher influence compared to the antenna. u-blox provides a diagram (page 19) showing the effect of the size of the ground plane for patch antennas. Unfortunately, the ublox document only lists 18mm and 25mm antennas. For 25mm antennas 7cm for the ground plane. of the Rectangular microstrip antenna with AMC ground plane which is obtained through HFSS simulations is given in Figure 5. The simulated impedance bandwidth, below 10 dB return loss, is between 2.3GHz to 2.88 GHz which meets the bandwidth specifications for ISM 2.4. The parameter S 11 of the Rectangular microstrip antenna. Note that this is a dipole antenna; you aren't using the fuselage as a ground plane.
