Abstract
The authors study the interference that occurs between the high-frequency and low-frequency portions of a proposed dual-band antenna when the antennas transmit into free space or into an inhomogeneous plasma layer. They analyze two limiting cases, namely, (1) when the apertures of the antenna are backed by infinite waveguide sections, and (2) when the apertures are backed by cavities and the rectangular cavity contains a probe in it and the ridged waveguide section does not. Numerical examples are presented.<>
