- How exactly a ground plane helps inproving antenna gain? What is the . . .
The ground plane is a conductor and metals reflect electromagnetic radiation Usually, a copper is used as a ground plane with thickness of 35 micron Some antennas are designed with etched ground plane If you have an antenna with ground plane (microstrip antenna) and without ground plane (sometimes called monopole), the antenna with ground
- Ground plane for PCB Antenna - Electrical Engineering Stack Exchange
In designing an antenna, the opposite result is desired -- you want it to radiate and receive RF, and for that it needs to be away from ground That's why the design you chose specifies no ground plane on any layer under the antenna area But -- many antennas, such as this one, are designed as monopoles Think of these as really only half an

Remark: One should read the text above to note that this text should be: "Figure 17: Typical Radiation Pattern of a 16 x 16 mm Patch Antenna" Figure 18: Typical gain and axial ratio of a patch antenna with respect to ground plane size Remark #1: "Figure 18: Typical gain and axial ratio of a patch antenna with respect to square ground plane size"
- Antennas and Ground Planes - Electrical Engineering Stack Exchange
A "ground plane" antenna removes half the dipole and substitutes the ground plane for that The inductance of the radiating element works with the capacitance between it and the ground plane to form the resonant circuit that gives the antenna proper tuning When used this way, the ground plane may be called a "counterpoise"
- antenna - Why does 1 4 wavelength have a ground plane and 1 2 . . .
Why does 1 4 wavelength have to have a ground plane and 1 2 doesn't? Here's how I think of it, a 1 2 wavelength dipole is just two 1 4 wavelength antennas back to back, and either can be considered the whip or ground plane Or, a 1 4 wavelength vertical is just 1 2 wavelength antenna with the ground plane as the other 1 4 wavelength element
- antenna - Building a ground plane for a CB radio - Electrical . . .
A basic antenna like a dipole is self-contained and requires no ground plane The concept of a ground plane is roughly to build a antenna half as long as a normal self-contained one, then add a mirror so that it looks like a complete antenna from the antenna side of the mirror We call this mirror a ground plane
- GPS antenna ground plane design considerations and limitations
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
- electromagnetism - Why must an antenna be connected to ground . . .
For a monopole antenna, that is correct In your textbook, the capacitor would be the capacitance between the antenna's monople and earth-ground In practice, not all electronic devices are connected to the earth Rather, it has a floated virtual "ground" that is shared onlny inside the device Think a mobile FM radio reciver and it's monopole
