High notch microstrip antenna array at Ka band

Abstract

This paper presents the experimental research and design for microstrip patch array antenna which resonates in Ka band. The proposed design consists of 4 microstrip rectangular patches. HFSS software is used for the simulation and analysis with four candidate structure. A material having a dielectric constant of 4.36 is used for the substrate material with the low loss tangent of 0.01. The dimension of the patches are varied to achieve better result. Design of all the antenna were within the range of 28 to 40 GHz. Designed Antenna exhibit the bandwidth range within 2.925 GHz to 7.7 GHz. By adjustment of the size of the patch i.e length, width and height, an appreciable gain within 9.62 dB to 9.98 dB was observed within the proposed design. The proposed antenna array will be able to scaled to a larger radiating structure. © 2023 IEEE.
