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. 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 (εr), substrate thickness (h) on the radiation ... A Cavity-Backed Broadband Circularly Polarized Slot/Strip ... The slot/strip loop antenna is fed by a single straight microstrip line. It is demonstrated that the cavity-backed slot/strip loop antenna can achieve an axial ratio (d3 dB) bandwidth of 20% with good impedance matching. I. INTRODUCTION Cavity-backed slot antennas have two major advantages over cavity-backed wire

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.
A highly compact cavity backed slot antenna is described. The antenna consists of a transverse slot in the flat broadwall of a deep single ridge waveguideThe wideband antenna characteristics using a ridged cavity configuration are demonstrated. Based on the limited amount of data obtained from the...
