New hybrid DRA for upper S-band and lower C-band applications

Abstract

A new hybrid T-Shaped monopole dielectric resonator antenna using conical cum hemispherical shaped dielectric ring resonator has been investigated. The newly introduced structure provides much better multipurpose application performances as compared to the published papers available in open literature. S11<; -10dB ranging 3.78-4.38 GHz has been experimented by simulation, showing 1.15:1 ratio bandwidth, i.e., greater than 14.7% impedance bandwidth at the centre of the band with 2.34 dBi gain. Such useful characteristics could be suitably utilized in designing monopole antennas for narrow band applications.
