Aperture coupled . Wide-Band Micro Strip Antenna Design -Srivatsa Bhargava J (4610-510-081-05891) MTech , CEDT, IISc Bangalore. Aim: Parametric Study, design and implementation of single patch, wide band Aperture coupled microstrip patch antenna for 2GHz frequency range. Abstract: Microstrip patch antennas are well suited for integration in to many Optimization of Aperture Coupled Microstrip Patch Antennas named Aperture Coupled Microstrip Patch Antenna. This new microstrip antenna demonstrates improvement on the impedance bandwidth from 5% to 50% and 4{5dBi gain enhancement. Due to their structural complexity, it is challenging job to get the expected gain and bandwidth improve-ments. AN APERTURE-COUPLED STACKED MICROSTRIP ANTENNA FOR GPS ... This thesis investigates a technique of stacking rectangular microstrip antenna elements to achieve dual frequency operation. In the particular configuration studied, two square patches are stacked on top of each other above a common ground plane. These elements are fed by the means of an aperture-coupled feed network.

Abstract: Aperture coupled microstrip slot antenna couples the patch antenna with microstripline through an aperture. To improve the radiation pattern, there are three techniques -First using reflector plate, second using cavity and third by adjustment of the phase angle using the movement of the patch antenna on the slot i.e. by adjusting the SWR distribution. An Introduction of Aperture Coupled Microstrip Slot Antenna An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The first aperture coupled microstrip antenna was introduced in 1985 by D M Pozar (4) Figure1: Aperture coupled microstrip slot antenna SLOT COUPLED MICROSTRIP ANTENNA FOR ULTRA WIDEBAND ... SLOT COUPLED MICROSTRIP ANTENNA FOR ULTRA WIDEBAND APPLICATIONS IN C AND X BANDS N. Ghassemi ... Abstract—This paper presents an aperture coupled microstrip ... microstrip square-ring slot antenna filled by an H-shaped slot for UWB applications, ... A Low Profile Multi-band U-shaped Aperture-coupled ... A Low Profile Multi-band U-shaped Aperture-coupled Microstrip Antenna with a Coil In this article, an L-shaped probe-fed, U-slot patch antenna with a coil element is studied. The L-shaped probe feed is used to enhance the impedance matching, which is necessary because of a low radiation resistance in the usable band.
