Abstract

In this paper, a linearly polarized half-mode substrate integrated waveguide (HMSIW) U-slot antenna is proposed. It is based on a combination of U-shaped slot etched in the HMSIW top wall and two shorts placed in this slot. Thanks to this configuration, a linearly polarized antenna with maximum radiation in the normal direction is obtained. The antenna is designed for the operating frequency band of 10 GHz with help of CST Microwave Studio. Experimental results prove that the antenna with a HMSIW-to-GCPW (grounded coplanar waveguide) transition radiates linearly polarized electromagnetic wave and achieves the impedance bandwidth of 3.2 % for reflection coefficient less than -10 dB and gain of 6.01 dBi.
