[ 1 ] - Groove Gap Waveguide (GGW) H-plane Horn ‎Antenna and a Method for Its Back lobe ‎Suppression

recently a new structure called groove gap waveguide (GGW) is ‎introduced to implement low loss microwave component devices ‎especially for millimeter wave applications. This paper presents a ‎new type of H-plane horn antenna making use of this new technology ‎in which backward radiation is significantly suppressed by ‎introducing a high impedance surface at the antenna aperture. The ‎high impe...

[ 2 ] - Development of A Compact and Low Profile ‎Cavity Backed Slot Antenna Using Microstrip ‎Gap Waveguide Technology

Proof of concept of a cavity backed slot antenna based on inverted microstrip gap ‎waveguide (IMGW) technology is presented. Since the antenna is operating based on the ‎first resonating mode of the cavity, it is more compact compared to the ordinary cavity ‎backed slot antennas in which the second cavity mode is used for radiation. Furthermore, ‎the proposed antenna element introduces lower lo...
