A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present some experimental results and try to give an idea of design parameters.
I. INTRODUCTION E CCENTRIC annular apertures find practical applications in waveguide junctions [1], wideband aperture antenna [2], cavity-backed circular patch antenna fed by coaxial line [3], and eccentric coaxial line [4]. Conformal mapping has been exten- sively used to analyze scattering from eccentric annular aper- tures [1], [4].

Standard DF antenna models are typically broadband antennas covering frequencies across the communications bands from HF through UHF, or approximately 20 MHz to 3000 MHz. The most common design is a cavity backed annular slot that incorporates ferrite elements for the lower HF frequency range. DUAL-BAND BEAM SCANNING REFLECTARRAYS AND NOVEL WIDEBAND AND ...
