Design of Compact Bow-Tie Slotted Antenna for Satellite Communication

Abstract

A printed antenna using slot loading technique is adapted in the design to achieve multiband. A rectangular microstrip (printed) antenna with a Bow-Tie shape slot embedded on the radiating patch using a glass epoxy substrate with dimensions 3.34 x2.47 x 0.16 cms. The antenna is simulated using 3D electromagnetic simulator software HFSS and fabricated using photolithography. Vector Analyzer is used to measure the experimental results. The fabricated antenna has return losses of -20.00 dB, -25.09 dB, and -26.45 dB at three independent frequencies 4.62 GHz, 8.14 GHz, and 12.41 GHz. The antenna operates at a frequency range of 4.62 GHz to 12.41 GHz, which supports satellite (space to earth) 5.441 and mobile communication 5.463 applications.
