by inserting U slot on Truncated rectangular microstrip patch antenna with H slot. By this impedance bandwidth enhancement method the antenna obtain the 10-dB return loss from 1.59 GHz to 2.67 GHz yielding 50.7% bandwidth enhancement. The antenna characteristics and radiation pattern are satisfactory for most of the wireless systems.

Broadband T-shaped microstrip-fed U-slot coupled patch antenna Jang, Y. -W. Abstract. Publication: Electronics Letters. Pub Date: 2002 DOI: 10.1049/el:20020364 The basic principles are illustrated here for a rectangular patch, but the principles apply similarly for other patch shapes. We use the cavity model to explain the operation of the patch antenna. 29 Y. T. Lo, D. Solomon, and W. F. Richards, “Theory and Experiment on Microstrip Antennas,” IEEE Trans. Antennas Propagat The patch antenna, microstrip transmission line and ground plane are made of high conductivity metal (typically copper). The patch is of length L , width W , and sitting on top of a substrate (some dielectric circuit board) of thickness h with permittivity .

The U-slot patch antenna was originally developed as a single-layer, single-patch wideband antenna. It has recently been shown that it can also be designed to perform a number of other functions.

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.
