A Substrate Integrated Waveguide (SIW) cavity-backed microstrip patch antenna for radar applications operating in X Band is designed. In order to increase the bandwidth, the SIW technology is used to build a circular cavity which surrounds a modified rectangular patch. The modified patch has truncated corners and two cuts in the lateral sides. Accurate electromagnetic investigation has been performed using CST Microwave Studio © in terms of radiation pattern, bandwidth, and matching. The prototype employs a Taconic RF-35 substrate with ε r = 3.5 and thickness of 1.52 mm. A good agreement between simulations and experiments is obtained. The proposed antenna is a promising candidate for a low-cost implementation of radar antenna arrays.

Abstract
A Substrate Integrated Waveguide (SIW) cavity-backed microstrip patch antenna for radar applications operating in X Band is designed. In order to increase the bandwidth, the SIW technology is used to build a circular cavity which surrounds a modified rectangular patch. The modified patch has truncated corners and two cuts in the lateral sides. Accurate electromagnetic investigation has been performed using CST Microwave Studio © in terms of radiation pattern, bandwidth, and matching. The prototype employs a Taconic RF-35 substrate with ε r = 3.5 and thickness of 1.52 mm. A good agreement between simulations and experiments is obtained. The proposed antenna is a promising candidate for a low-cost implementation of radar antenna arrays.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
