Development of A Compact and Low Profile Cavity Backed Slot Antenna Using Microstrip Gap Waveguide Technology
Proof of concept of a cavity backed slot antenna based on inverted microstrip gap waveguide (IMGW) technology is presented. Since the antenna is operating based on the first resonating mode of the cavity, it is more compact compared to the ordinary cavity backed slot antennas in which the second cavity mode is used for radiation. Furthermore, the proposed antenna element introduces lower lo...
متن کاملDynamic Thinning of Antenna Array Using Genetic Algorithm
Thinning is a technique by which the total number of active elements in an antenna array is reduced without causing major degradation in system performance. Dynamic thinning is the process of achieving this under real time conditions. Stochastic techniques have been useful in the design of thinned arrays. However while applying the technique to large 2-D arrays, under changing conditions proble...
متن کاملReduction of Mutual Coupling between Cavity-Backed Slot Antenna Elements
Maintaining mutual coupling suppressing structure as simple as possible is becoming attractive in the electromagnetic and antenna community. A novel parasitic patch structure that can reduce mutual coupling between cavity-backed slot antenna elements is proposed and studied. The structure consists of only a simple rectangular patch inserted between the antenna elements, and it is therefore low ...
متن کاملA Broadband Low Cross-Polarization U-Slot Patch Antenna Array Based on Differential Feed
Abstract—In this paper, a single layer 4× 4 U-slot patch antenna array based on differential feed was developed to achieve a wide bandwidth and low cross polarization with a simple feed network. A U-slot was cut on a radiation patch to realize a wideband performance, and a microstrip-line fed structure was adopted to make the patch and feed network placed in a single layer. In order to reduce e...
متن کاملDynamic Thinning of Antenna Array Using Differential Evolution Algorithm
Dynamic thinning is a process by which the total number of active elements in an antenna array is reduced under real time conditions without causing major degradation in system’s performances. This paper suggests a technique by which a thinned antenna array is designed by simple differential evolution(DE) algorithm overcoming the difficulties of large and rugged solution space and slow rate of ...
