IDEALS @ Illinois: Cavity-backed T-fed slot antenna

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. Design and Fabrication of a High-Gain 60-GHz Cavity-Backed Design and Fabrication of a High-Gain 60-GHz Cavity-Backed Slot Antenna Array Fed by Inverted Microstrip Gap Waveguide Abstract: This communication deals with the design of a 16 × 16 slot array antenna fed by inverted microstrip gap waveguide (IMGW). The whole structure designed in this communication consists of radiating slots, a groove gap Slot Antenna - an overview | ScienceDirect Topics

The electric monomicrostrip dipole antenna consists of a thin electrically conducting element formed on one side of a dielectric substrate; the ground … US6414647B1 - Slender omni-directional, broad-band, high…

A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz.

Slot antennas with a backing cavity for unidirectional radiation are investigated with the aim of achieving a thin structure capable of reasonably broadband operation. By tuning together the slot length and the cavity cross‐section, a very low‐profile cavity‐backed slot (CBS) is demonstrated.

This disclosure demonstrates a new class of Ultra-Wide Band (UWB) AMC with very large fractional bandwidth (>100%) even at lower frequencies (<1 GHz). This new UWB AMC is enabled by recognizing that any AMC must be an antenna in order to … US6954177B2 - Microstrip antenna array with periodic filters… An antenna unit formed in the shape of a hollow box comprising (a) a substrate forming the front side of the antenna unit, (b) a first microstrip antenna array formed on the substrate, (c) a second microstrip antenna array formed on the … US4843403A - Broadband notch antenna - Google Patents The notch antenna device 10 has a mount 14 and a narrow slot 15 that are interconnected by a gradual transition as shown in FIG. 1.
