Abstract
We present a simple method to design a resonant cavity antenna (RCA) that resonates in two bands by employing two dielectric superstrates of thicknesses and positions determined by a step-by-step, non-iterative process. The method models the RCA as two cavities, each corresponding to one operational band, which allows for a dynamic control of the separation between the bands. The antenna is analytically designed and performance is evaluated using a commercial software.
