Design of Compact Bow-Tie Slotted Antenna for Satellite Communication

Abstract

A printed antenna using the 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 high-frequency structure simulator software and fabricated using a photolithography process. Experimental results are measured using a vector analyzer. the proposed antenna is resonating at three different frequencies 4.62 GHz, 8.14 GHz, and 12.41 GHz with a return loss of -20.00 dB, -25.09 dB, and -26.45 dB respectively. The antenna is resonating between 4.62 GHz to 12.41 GHz frequency which covers applications in the field of satellite (space to earth)5.441 and mobile communication 5.463.
