摘要：
In this paper, design of a high gain SIW-fed antenna for Q-band (33 GHz-50 GHz) applications is presented. The antenna has multilayer structure. It consists of 3 substrates, a metal plate between second and third substrate layers and a patch on top layer. Bottom layer substrate is used for SIW feed design. Middle layer substrate is used to bond SIW substrate and metal plate, and top layer substrate is used for patch design. In order to enhance gain of the antenna a rectangular aperture is prepared on the metal plate which acts as a cavity. Antenna has dimensions of 21.5 mm * 18 mm * 1 mm. Proposed antenna bandwidth ranges from 44.4 GHz to 50.2 GHz, covering 5.8 GHz of Q-band. Antenna efficiency is above 90% over operational frequency range. Gain of the antenna is above 9 dB with peak value of 11 dB at 48.8 GHz. The antenna has low cross-polarization levels on phi = 0 plane and at theta = 0 direction. Proposed antenna is suitable for various millimeter-wave applications such as sensing, body imaging, indoor scenarios, new generations of wireless networks and future satellite communications.
