A Dielectric Resonator loaded Substrate integrated waveguide cavity backed slot antenna (Sidra) is proposed for two slot polarizations and orientation. US5943016A - Tunable microstrip patch antenna and feed network… A patch antenna is provided with one or more tuning strips spaced therefrom and RF switches to connect or block RF currents therebetween. When a conducting path for RF current is connected between the tuning strips and the patch, the … US5245745A - Method of making a thick-film patch antenna… Method and structure are disclosed for production of a thick-film antenna. A thick-film microwave patch element (26) is patterned onto one surface of a dielectric substrate (32) and a thick-film reference surface (24) disposed onto the …
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

Jan 19, 2017 · In this example a cavity-backed slot/strip antenna is simulated in XFdtd using the XACT meshing feature. The simulated results for return loss, axial ratio, and gain are compared to measured results. The antenna design and measured results are taken from . A CAD representation of the antenna structure is shown in Figure 1. Microstrip Patch Antennas - University of Texas at El Paso Microstrip Patch Antennas Slide 18 The rectangular patch is the most widely used configuration for microstrip patch antennas. Transmission-Line Model It is the easiest approach to model and analyze the microstrip patch antenna. It is also less accurate, but gives a good physical insight. EM Cavity … Enhancing the Bandwidth of a Microstrip Patch Antenna Enhancing the Bandwidth of a Microstrip Patch Antenna using Slots Shaped Patch Atser A. Roy, Joseph M. Môm, Gabriel A.
