What is a ground plane antenna used for?
In telecommunication, a ground plane is a flat or nearly flat horizontal conducting surface that serves as part of an antenna, to reflect the radio waves from the other antenna elements.
When should you use a ground plane?
By carefully planning out the layer stackup configuration of a multi-layer circuit board, the PCB designer can use ground planes to help control the electrical performance of the board. By using a ground plane between two active signal layers, the crosstalk between the signals on those layers can be eliminated.
What is the size of antenna?
The size of the antenna comparable to the wavelength of the signal (at least `lambda//4`) . So that the antenna properly senses the time variation of the signal . For an e.m waves of frequency 20 kHz, the wavelength `lambda` is 15 km . Obviously such a long antenna is not possible to construct and operate .
What does grounding a plane mean?
If an aircraft or its passengers are grounded, they are made to stay on the ground and are not allowed to take off.
What is the radiation characteristics of the antenna?
As we know that the radiation characteristics of the antenna is depends on the size of the ground plane. If we are using full ground plane (example micrositrip antenna), the radiation characteristics may be unidirectional. Generally, for microstrip antenna, the size of ground plane is 6h+W and 6h+L considering. But this is approximation analysis.
What size ground plane do I need for a monopole antenna?
The amount/size of the “ground-plane” required for the optimal performance of a monopole antenna is determined by the frequency you are transmitting/receiving at. In this case, it’s a multi-band antenna the customer is using (it can be used from 700 MHz – 2700 MHz) so the ground plane required could be anywhere from 4-64 square inches.
How many radials are in a quarter wave antenna?
Quarter 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.
Are the radiation characteristics of microstrip antenna unidirectional?
If we are using full ground plane (example micrositrip antenna), the radiation characteristics may be unidirectional. Generally, for microstrip antenna, the size of ground plane is 6h+W and 6h+L considering. But this is approximation analysis.
