Abstract

The cavity-backed slot (CBS) antenna, is a lightweight, conformal radiator, and is considered efficient due to its electrical size and material loading within the cavity. Having these characteristics, the CBS antenna is an ideal choice for experimentation as a tuneable antenna. The concept of using a ferrite to magnetically tune a CBS antenna is not new; however, the literature lacks any substantial work to verify the capability of such an antenna. The present study focuses on experimentally examining the characteristics of a ferrite-tuned cavity-backed slot antenna utilizing magnetostatic wave modes.
