A SIW-based Antenna with Paired Radiating Arms for Q-Band Application

Abstract

An antenna which contains paired radiating arms is proposed in this paper. The antenna utilizes a coupling slot on a substrate integrated waveguide (SIW) transmission line for feeding the paired arms. On each radiating arm, a shorting-pin is loaded respectively. Measured results clear that the proposed antenna achieves an $S_{11}<-10$ bandwidth of 36.6-40.2 GHz and a gain of 7.9 dBi at 38GHz. And thus the antenna is a practical candidate for the fifth generation (5G) millimeter-wave (mmW) wireless applications.
