Dual slot microstrip antenna device - Ball Brothers ... 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. Microstrip Patch Antenna Design for Ku Band Application [17] A. A. Eldek and C. E. Smith, “Rectangular Slot Antenna With Patch stub for Ultra Wideband Applications and Phased Array systems,” Progress In Electromagnetics Research, PIER 53 , pp. 227–237, 2005. Band IV/V (UHF) TV Slot Antennas 470 - 806 MHz 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 ... International Journal of Engineering Trends and Technology ...
A $4 \times 4$ slot array has been designed using this concept. The goal of this letter is to demonstrate the viability of groove gap waveguides and coaxial cavities for the design and fabrication of high-frequency single-layer slot-array antennas. Simulation results as well as measurements are shown.
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. An electrical signal feed assembly is connected with the conductors for exciting the Development of Microstrip Patch Antenna Design for S-Band Microstrip patch antenna used to send onboard parameters of article to the ground while under operating conditions. The aim of the paper is to design as tacked nearly square microstrip patch antenna design for S band 2 GHz to 4 GHz and study the effect of antenna dimensions Length (L), and substrate parameters relative Dielectric constant (ε r), substrate thickness (h) on the radiation A cavity-backed coplanar waveguide slot antenna array 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.

In one embodiment, the present invention provides an antenna array for transmitting one or more beams in a communication system. The antenna includes a cavity slot antenna array that is adapted to be operatively connected to a beam forming module (e.g., via a plurality of signal feed lines that are connected to radiating signal probes). The antenna array has one or more cavity slot columns
