In [3,4,5], various cavity-backed antennas with different cavity shapes and patch structures were discussed. In , SIW cavity-backed dual-band circularly polarized (CP) antennas with planar configurations were investigated. A dual-mode SIW cavity-backed triangular ring slot antenna was proposed and developed for dual-band application in . Cavity-Backed Slot Array | Antenna Magus Cavity-backed slots allow for very efficient low-loss structures at high frequencies, but often require complex feed structures. By using a single cavity backing for a number of slots and leveraging the modal distribution in the cavity to realize the excitation distribution of the slot array the complexities of the feed structure can be greatly reduced.

Figure 1. Geometry of the most common slotted waveguide antenna. The front end (the open face at the y=0 in the x-z plane) is where the antenna is fed. The far end is usually shorted (enclosed in metal). The waveguide may be excited by a short dipole (as seen on the cavity-backed slot antenna) page, or by another waveguide.
Abstract: This communication presents a cavity-backed slot antenna (CBSA) array for the estimation of direction of arrival (DOA). This new CBSA employs an alternative feeding structure to excite the radiation of cavity-backed slots and transfer the area for RF module implementation from the front surface of the array aperture to the bottom behind the cavity. Design Of A Wideband Dual-polarized Cavity Backed Slot Antenna
This paper deals with a slot array antenna withbackward excitation that prevents radiation into the back-side by installing a cavity. With a view to simplifying thefabrication process, all slots in the array share one cavity. Adesign guideline is discussed for reducing mutual couplingbetween the elements.
