Objective
To design a Ring Dielectric Resonator Antenna with an air gap between the dielectric resonator and ground for bandwidth enhancement.
Dielectric Resonator Antenna
Dielectric Resonator Antenna is a radio antenna used at microwave frequencies and higher.
Consists of dielectric resonator and a ground plane.
Can be excited with different feeding methods.
Ring DRA
Proposed DRA formed by removing the central portion of the dielectric material of the cylindrical DRA.
According to perturbation theory, the removal of dielectric material would result in lowering of the Q-factor and increase in the resonant frequency.
Conclusion
The impedance bandwidth of 86% is obtained as the band covers the range of frequency from 3.2 GHz to 7.39 GHz.
This antenna can be use for WLAN as well as RFID applications.
The proposed ring DRA is suitable for broadband wireless communication system.
