Abstract :
In this paper, the effects of curvature on the resonant input impedance and radiation pattern of a cavity-backed, rectangular, aperture antenna that is conformal to the surface of a perfectly conducting prolate spheroid are investigated. The radiation pattern and input impedance are calculated using a hybrid finite element-boundary integral approach. To gain further insight, the behavior of the resistive part of the resonant input impedance of the antenna is compared with that of the same type of antenna that is conformal to the surface of a perfectly conducting circular cylinder as the curvature is varied.
