ABSTRACT

Microstrip patch antennas are the most used antenna types in the present. Having advantageous mechanical characteristics like low profile, light weight, planar but conformal to non-planar structures, easy to fabricate, flexibility in terms of electromagnetic parameters - radiation pattern, gain, impedance, polarization and low cost they are being preferred as conformal antennas. In this paper, a comparative analysis will be drawn towards the performance characteristics of a conformal antenna with its planar counterpart in terms of its bandwidth and polar radiation pattern. This analysis can aid in making a right design choice between a conformal antenna or a planar antenna, specific to the application. For this analysis, a Microstrip Patch antenna operating at 2.4GHz (ISM band) is taken as the reference antenna to draw the comparison.
