Abstract
In this paper, sub-wavelength passive periodic struc-tures are used to create high isolation between the transmitter (Tx) and receiver (Rx) antennas designed at 26 GHz. The periodic electromagnetic bandgap (EBG) structures composed of square mushroom shapes are used between Tx and Rx (TRX) antennas for increasing the isolation from 22 dB to 50 dB experimentally. The results are compared in terms of simulation and measurement and a close agreement is found between them. Moreover, the results are further used to extract system performance targeting joint communication and radar sensing (JC&S) applications.
