Ceramic Patch Antennas Abracon Patch Antennas are linear and Right Hand Circular Polarization (RHCP) ceramic-type antennas that offer multi-band frequency operations with high gain. The ceramic patch antennas offer 50Ω impedance and a surface mounting termination style. These patch antennas are available in a low-profile, small form factor package. Applications include remote IoT, ISM applications, wireless communication, and more.
