Polytetrafluoroethylene Glass Microfiber Reinforced Slotted Patch Antenna for Satellite Band Applications

摘要

In this paper, a new configuration of triangular and diamond slotted patch shape microstrip fed low-profile antenna is introduced on Polytetrafluoroethylene glass microfiber reinforced material substrate for satellite applications. The antenna is composed of a rectangular shape patch slotted with eight triangles and two diamonds and elliptical slotted ground plane. The rectangular shape patch is obtained by cutting two diamond slots in the middle of the rectangular patch and six triangular slots on the left and right side of the patch, and two triangular slots in the up and down side of the patch. The slotted radiating patch, the elliptical slot ground and microstrip fed allow widening the matching bandwidth. Using a finite element based simulator, a parametric investigation was performed for the optimization. The proposed antenna offers a-10 dB impedance bandwidth of 1,020 and 1,350 MHz, respectively, and relatively stable and omnidirectional radiation patterns in the matching band.
