1. What are RF antennas used for?
RF antennas are used to transmit and receive radio frequency signals in applications like Wi-Fi, cellular communication, GPS, and IoT devices.
-
2. What is antenna gain, and why is it important?
Antenna gain measures how effectively an antenna directs or focuses energy compared to an isotropic source. Higher gain antennas provide better range and signal strength in a specific direction.
-
3. What materials are used in RF antenna construction?
Common materials include copper, aluminum, stainless steel, and printed circuit boards. Copper is widely preferred for its conductivity and ease of fabrication.
-
4. What is polarization in RF antennas?
Polarization refers to the orientation of the electric field of the signal. It can be linear (vertical or horizontal) or circular. Matching the polarization between the transmitter and receiver improves efficiency.
