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.
Effect of the Different Shapes: Aperture Coupled Microstrip Slot Antenna coupled microstrip slot antenna couples the patch antenna with microstripline through an aperture. One effective way to One effective way to increase the impedance band-width is to change the patch shape, feed shape and the slot shape. A Review of Aperture Coupled Microstrip Antennas: History, Operation ... printed slot antennas fed with microstrip lines [6], but the bidirectionality of the radiating element was unacceptable. At some point in the summer of 1984 we arrived at the idea of combining these two geometries, using a slot or aperture to couple a microstrip feed line to a resonant microstrip patch antenna. After considering the application of small hole coupling theory to the fields of the microstrip line and the microstrip antenna, we designed a prototype element for testing. Our ...

Aperture coupled microstrip antenna with quasi-planner… A new combination of aperture coupled microstrip antenna and a quasi-planner surface mounted short horn is demonstrated to increase the gain of patch antenna by 4.2 dB. The structure has 12.4% bandwidth. The presence of quasi-planner has improved the back-lobe level by 5.4 dB. Microstrip U-Slot Aperture Coupled Antenna for Wimax… The new antenna was a probe feed rectangular microstrip antenna on a unity permittivity substrate with an internal U shaped slot.The aperture coupled feed is especially attractive, since, the ground plane of feed line shields the antenna half space from spurious radiation emitted by coplanar feed lines.
