1. What types of RF antennas are available?
Common types include omnidirectional, directional, patch, dipole, and Yagi antennas, each serving specific use cases based on signal coverage and range requirements.
-
2. 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.
-
3. What is an embedded RF antenna?
Embedded antennas are integrated into devices such as smartphones or IoT sensors, designed to be compact while maintaining signal performance.
-
4. Can RF antennas be used for both transmitting and receiving signals?
Yes, most RF antennas are designed to work bidirectionally, capable of both transmitting and receiving signals within their specified frequency range.
