An Introduction of Aperture Coupled Microstrip Slot Antenna How can the answer be improved? Aperture Coupled Microstrip Antenna Design and Analysis Aperture Coupled Microstrip Antenna Design and Analysis Michael Paul Civerolo A linearly-polarized aperture coupled patch antenna design is characterized and optimized using HFSS antenna simulation software [1]. This thesis focuses on the aperture coupled patch antenna due to the lack of fabrication and tuning documentation 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
The aperture coupled patch antenna microstrip feed line, substrates, ground plane slot, and patch dimensions are varied in HFSS to determine effects on antenna performance. The operating frequency, VSWR, percent bandwidth, polarization ratio, and broadside gain are observed for each configuration.

Abstract: A microstrip slot antenna is very small and lightweight still it has the problem of back radiation due to.To reduce the back lobe a technique introduces i.e. aperture coupled microstrip slot antenna which reduces the back lobe as well as increases the bandwidth of the antenna.
An aperture-coupled microstrip patch 101 relies on an aperture, or coupling slot 102, to couple electromagnetic energy from a feed circuit 104, 105 to the microstrip patch antenna 101, as is shown in FIG. US4843403A - Broadband notch antenna - Google Patents In designing antenna structures, it should be kept in mind that the antenna designer must make the antenna perform a desired electrical function such as transmitting/receiving linearly polarized, right-hand circularly polarized, left-hand … US4259670A - Broadband microstrip antenna with automatically… Variable impedance devices (e.g., series resonant circuits and/or transmission line tuning stubs) are connected to predetermined locations on a microstrip radiator patch for changing the effective resonant dimensions of the antenna as a …
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. The coil contri...
