A finite element-boundary integral method has been developed to investigate the impedance and radiation characteristics of planar and conformal cavity backed microstrip patch antennas. In case of conformal antennas, the radiating element is mounted on a cylindrical surface. The effect of curvature is analysed and the impact of the cavity size on the performance of the radiating element is investigated. For the examples considered, it is shown that the simulated results-are in good-agreement with measurement. © 2007 SBMO.
