Microstrip antennas, also called patch antennas, are very popular antennas in the microwave frequency range because of their simplicity and compatibility with circuit board technology.
The rectangular patch antenna is one of the most commonly used microstrip antennas. The pin-fed patch is the simplest patch antenna to construct, and does not suffer from feed network radiation. The pin-feed also allows simple impedance control.
