Antennas like horn, Yagi- Uda and cavity backed slot can produce high gain. The horn is usually bulky, therefore an integrated horn antenna with fairly low proflle at 60GHz was presented in [8] that produces 14.4dB gain. However, the antenna size is still large (5:2‚ £ 4‚). Active Phased Array of Cavity-Backed Slot Antennas With ... 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 dissertation is a surface integrated waveguide cavity backed slot antenna (SICBSA) fed. by microstrip lines. This is a new approach, in which the use of a surface integrated. waveguide (SIW) cavity will very effectively reduce surface wave propagation.

Antennas: The Slotted Waveguide Antenna 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. 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.

A wideband cavity-backed slot antenna includes an enclosure having a slot, a balun located proximate the slot, a feed extending through the enclosure to the balun, and a plurality of coupled lines proximate the balun and distal to a location at which the balun is coupled to the feed. Design Of A Wideband Dual-polarized Cavity Backed Slot Antenna A new technique for designing wideband dual-polarized cavity-backed slot antennas is presented. The structure is in the form of a double-resonant, dual-polarized slot antenna backed by a shallow substrate integrated cavity with a depth of approximately λ 0/10, where λ 0 is the wavelength in free space. The presence of the
cavity-backed slot antenna arrays with the different WLRs are designed and prototyped on the RO3006 substrate using PCB technology at 60 GHz bands. Fig. 9 shows the geometry of these 2 2 4 antenna arrays, in which the feeding SIW is modified with the inductive via-hole.
