A Practical Approach for Design of a Wideband Microstrip Patch Antenna Conformed to Cylindrical Surface

Conformity of the antenna to the mounting surface is the most essential requirement of modern communication system, whether it be antenna mounted on vehicles or airborne applications primarily due to the aero dynamical advantages of such antennas. In this paper we present the analysis of a inset microstrip line fed patch on cylindrical substrate with electrically small radius of 0.1 times free space wavelength. We try to analyse the effect that the bending has on the resonant frequency, inset length of the feed line of the patch antenna. We present the design dimensions, S11 & Radiation pattern results for the designed conformal patch antenna.
