A new aperture coupled microstrip slot antenna - IEEE Abstract: A new aperture coupled design is proposed for microstrip slot antennas to improve their radiation performance. The proposed design is based on a new aperture coupling technique in which the slot is fed by a microstrip line and coupled to several parasitic patch radiators etched on the opposite side from the slot. Design and Optimization of Aperture Coupled Microstrip In this paper genetic algorithm has been used for optimization of aperture coupled rectangular microstrip patch antenna (ACMPA) dimensions, It was exactly used to optimize the patch length, the slot dimensions in the ground plane and the dimensions of the feed line.

Figure 2-1 shows the aperture coupled microstrip antenna in block diagram form. The feed line creates an electric field in the aperture (ground plane slot), which induces surface currents on the patch. The patch edges perpendicular to the feed line create fringing fields that radiate into free space.

Effect of the Different Shapes: Aperture Coupled Microstrip Slot Antenna 105 Microstrip Feed Line Feed substrate dielectric constant should be in the range of 2 to 10.A thinner feed substrate results in less spurious radiation from feed lines, but higher loss. A compromise of 0.01 λ to 0.02 λ is usually good.
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
