Bandwidth Enhancement of T–slot loaded Proximity Coupled Equilateral Triangular Microstrip Antenna for Multiband Operation

Mahesh C P, P M Hadalgi

Abstract :

In this paper, a compact size proximity coupled equilateral triangular microstrip antenna is designed, analyzed and faicated. The bandwidth enhancement of microstrip antenna is done by cutting T–slot on radiating patch of equilateral triangular. The characteristics of the antenna are obtained in terms of bandwidth, gain and return loss, these properties are compared with the conventional microstrip antenna. It is shown that by choosing suitable slot dimension and location of the slot, the impedance bandwidth can be improved up to 22.03% as compared to conventional antenna with an bandwidth of 6.97%. This antenna may find its applications in WIFI IEEE 802.11, IMT (International Mobile Communication) and in radar systems. The results are presented and discussed.
