A broadband cylindrical dielectric resonator antenna
(DRA) energized with an L-strip feed is presented The novel exciting
technique achieves a 2:1 VSWR bandwidth of 18%. The variation of
bandwidth for different feed parameters is also studied

Abstract:
Bandwidth enhancement of a rectangular microstrip
antenna using a T-shaped microstrip feed is explored in this paper.
A 2:1 VSWR impedance bandwidth of 23% is achieved by employing
this technique. The far-field patterns are stable across the pass band.
The proposed antenna can be used conveniently in broadband communications
