IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, … IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 54, NO. 5, MAY 2006 1461 Size Reduction of Cavity-Backed Slot Antennas Wonbin Hong, Student Member, IEEE, Nader Behdad, Student Member, IEEE, and Kamal Sarabandi, Fellow, IEEE Abstract—A technique for reducing the dimensions of the cavity of a cavity-backed slot antenna (CBSA) is presented, which facil- Radar Basics - Slot Antennas Slot Antenna. Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide. But also older large phased array antennas used the principle because the slot radiators are a very inexpensive way for frequency scanning arrays. . Slot antennas are an about λ/2 elongated A Compact Wideband Dielectric Resonator Antenna with a

Cavity-Backed Dumbbell-Shaped Slot Antenna for C

A crossed slot antenna, a method of fabricating same and a method of designing same. The antenna includes a cavity structure having conductive material on opposed surfaces thereof; and two slots in said conductive material, the slots … US6031503A - Polarization diverse antenna for portable…

The CBSA Antenna structure consist of a rectangular waveguide at standard dimension (WR-159).The another component used is a cylindrical cavity which backs a basic slot antenna. The whole structure is feed by the rectangular waveguide. There are 3 slots on the topmost circular disc Cavity Backed Slot Antenna

A COMPACT DUAL-CIRCULARLY POLARIZED CAVITY-BACKED RING- SLOT ... on top of the center conductor of a ring-slot antenna. Two cavity-backed ring-slot antennas are presented with unidirectional radiation properties. The first is a linearly polarized CPW-fed ring-slot antenna. A T-shaped CPW feed was used to capacitively excite the ring-slot structure. The bottom of the cavity is formed by an AMC 60GHz Slot-Array Antenna Design Based on Gap Waveguide Cavity and... Index Terms— Double-layer structure, cavity-backed slot antenna, waveguide slot-array, corporate feed network. I. INTRODUCTION Waveguide slot array antennas are expected to provide high aperture efficiency and also high gain at mm-wave frequencies due to the lower losses in the distribution networks [1-2]. Cavity backed dual slot antenna for gain improvement - Li - 2010... By using dual slot at the cavity edges to substitute a single slot at the cavity center as the radiating element, gain of the cavity backed slot antenna has been improved about 1.7 dB whereas its total size is little reduced.

Utilizing slot cavity geometry, the RD series antenna is capable of wideband, low VSWR transmission for up to 20 channels. This capability makes it possible for stations to utilize a single antenna for Analog and DTV channel allocation and relocation assignments which fall within 20 channels of each other. Cavities are segmented into four groups of twenty channels. This allows overlapping of ...
