Inset fed patch antenna with five slots

Abstract

In the following paper, a rectangular microstrip patch antenna with two main kinds of slots which are rectangular slots that are more frequently used and L shaped slots are designed, simulated, built and tested. Furthermore, a circular-shaped input feed with 1 mm diameter was chosen to feed the antenna from the edge of the inset-fed part of the antenna. Moreover, an RT6002 substrate with 0.76 mm thickness was the raw material of the antenna. Eventually; this design was capable of acheiving a gain of 8.2 dB with a remarkable value of-15.2 dB for S11 in the manufactured antenna, for a Ku band frequency of 14.4 GHz as Vector Network Analyzer measures. As this design has a Ku band frequency, it could be used for satellite communications such as NASA's Tracking Data Relay Satellite, backhauls broadcasting, and vehicle speed detection.
