Slot coupled microstrip patch antenna

By Publisher

An antenna array is disclosed wherein radiators are parasitically coupled to each other, forming an efficient feed network. Parasitic coupling of patches is arranged so that some patches are fed by a plurality of other patches which are …

Industry News 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. Compact and Broadband Microstrip Antennas - coupled feed, a capacitively coupled feed, or a three-dimensional microstrip tran- sition feed can yield impedance bandwidths greater than 40% with good radiation characteristics for a single-patch microstrip antenna. Analysis of slot coupled microstrip patch Slot coupled microstrip patch antenna, shown in Figure 1.1.d is proposed by Pozar in 1985, [2]. It is also a noncontacting feed method. The structure consists of two dielectric layers, which may have different thickness and dielectric constants.

Keywords: Microstrip patch antenna, Return Loss, Radar, Slot, Wi-Max. 1.INTRODUCTION The need for a low profile and compact antennas is on rise with the rapid development of the wireless communication devices. Due to low fabrication cost and compactness of the patch antennas many researchers are working in this Dual-band Aperture-coupled CP Antenna with Single Cross-slot A dual-band aperture-coupled CP microstrip patch antenna is presented. It contains only one radiator and one cross-slot. The vertical and the horizontal slot are of equal length which is about 1.0 to 1.5 times the side-length of a square microstrip patch antenna. It is found that the current on the patch flows sequentially in +y, +x, -y,
