Dual-band Cavity-backed Slot Antenna Using Series Resonator
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. US3810183A - Dual slot antenna device - Google Patents A dual slot antenna assembly is disclosed herein and generally includes a pair of concentrically positioned and radially spaced cylindrical conductors defining a pair of circumferential slots which are longitudinally spaced one-half wavelength apart at the anticipated operating frequency of the antenna device.

In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes.Slot antennas are known for their sturdy, planar structure and have long been a prominent part of wireless systems.
A Novel Circular Polarized SIW Square Ring-slot Antenna In Ref. 4, a circular ring-slot antenna embedded in a single-layered SIW with a microstrip-to-SIW transition was presented. The antenna had a wider AR bandwidth 2.3% and a wide impedance bandwidth 18.74% than the cavity backed crossed-slot antenna [2-3], but its gain was less than 6 dBi, and the antenna had a high level of cross-polarization.
