Study and Implementation Frequency Reconfigurable of Dielectric Resonator Antenna Using Ground Feed Switch for S Band Applications

Abstract

A rectangular Dielectric Resonator Antenna (DRA) feeds by two microstrip taper with one is presented, one feed has grounded switch. This switch can control the frequency band. The step by step for the rectangular dielectric resonator antenna design is carried out. The overall antenna size is 30×40×11.635 mm. The proposed antenna achieves the goal of obtaining frequency reconfigurable. The – 10 impedance frequency range when switching off is from 2.705 to 3.02 GHz while switch on is from 3.09 to 3.3 GHz. In additional the proposed antennas have good radiation efficiency above 90%. The proposed antenna is suitable for Indoor Access point S-Band Applications.
