# U slot microstrip patch antena

By Editor

The microstrip antenna is formed on a separate dielectric slab above the ground plane and the two structures are electromagnetically coupled through an electrically small aperture in the ground plane between them. In the original paper by Pozar, the aperture was in the form of a small circular hole (Fig.2.12).

This antenna structure has recently been found experimentally to provide Aug 30, 2016 Fig. 5.

Rhombus shape slot loaded rectangular microstrip antenna for dual band operation by embedding two rhombus shape slots on the patch with copper as ground plane, the bandwidth of C band is enhanced from 2.06% to 20.4% without affecting the operating bandwidth at C-band. 1: Return Loss Vs frequency plot of patch antenna. U-slot microstrip patch antennas were originally developed for bandwidth broadening applications. Recently, it was found that the U-slot technique can also enable the patch antenna to perform other functions, including: dual-band and tri-band operations, as well as for circular polarization applications. The versatility of U-slot patch antennas will be discussed in this paper. The proposed antenna is comprised of16 rectangular patchs with U-slot and microstrip line feed network. Rectangular patch antennas are arrayed in $4\times 4$ formation to obtain a high gain. The -10dB reflection coefficient bandwidth of array antenna is 4.91 GHz (25.16 GHz −30.7 GHz) and the maximum gain is 17.01 dBi in the y-z plane.

## The design of inverted U-slot aperture coupled wideband microstrip patch antenna is analyzed and discussed in this work. The performance parameters of the antenna as detailed in Table 3 are achieved in a good agreement after applying slight modifications to the base design to reach up to the final optimum wideband design.

In telecommunication, a microstrip antenna usually means an antenna fabricated using These slots act as an array and have the highest directivity when the antenna has By using this site, you agree to the Terms of Use and Privacy Nov 8, 2018 Abstract ─ In this article, a well matched U-Slot. Microstrip Patch Antenna (MPA) with two paratactic elements is designed and simulated.

### This characteristic can be obtained by embedding a U-slot in the patch and hence the radiating patch includes a pair of step-slots. In this paper, we propose a dual-band microstrip patch antenna with u-shaped slot fed by coaxial feeding technique. The proposed antenna is designed, simulated and optimized using Ansoft HFSS Vs 13.

May 20, 2008 A novel single layer single probe fed T-slot broadband rectangular patch antenna is reported in this article. A T-slot patch antenna gives an impedance bandwidth (-10dB return loss) of 25.23% with an average gain of about 7.43 dBi over the entire passband and peak gain of 9.88 dBi. It gives good radiation patterns in entire the pass band.

## The microstrip antenna consists of the rectangular patch on the top of the dielectric substrate and over which a u-shaped slot has been made to reduce the size of the antenna. The reduction in the size of the antenna results in improved gain and the return loss of the antenna.
