چکیده
|
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 losses compared to a microstrip patch thanks to the surface wave suppression and lower dielectric loss of the air filled imgw cavity. a sample antenna is designed and fabricated to operate at 9.6ghz and quite good agreement between simulation and measurement results is observed.
