Antenna is an important component of communication systems. Microstrip antenna find use in a number of application due to its features such as light weight, small size, easy to mass produce etc. But a very serious limitation of microstrip is its low bandwidth typically in the range of 1-2%. This paper investigates experimentally an alternative approach in the bandwidth enhancement of microstrip antenna. The antenna is designed to operate at a resonant frequency of 1.5 GHz with glass epoxy used as dielectric material. The return loss and radiation characteristics of the proposed microstrip antenna are compared with the reference antenna radiation characteristics, which is a conventional circular patch antenna.
