A rectangular slot antenna with improved bandwidth ... A rectangular microstrip slot antenna fed by a microstrip line, which achieves a very large bandwidth on a relatively thin substrate, is presented. The performance is achieved by employing a combination of a rectangular slot in the ground plane, and the use of the microstrip line perpendicular to the rectangular slot. Design of triple-layer double U-slot patch antenna for ... Many techniques have been proposed to design microstrip patch antennas with multiband characteristics. In the proposed antenna design, a combination of dual U-slot and multiple layers is used to get multiple bands and wide bandwidth. Analysis of U-slot loaded Patch for Dualband Operation Index Terms: Microstrip antenna, patch antenna, U- slots loaded patch and dual band antenna. 1. INTRODUCTION Microstrip antenna inherently has a low bandwidth that limits its application in practice. Several approaches have been made to improve the bandwidth of the single layer patch antenna, such as use of a thick or foam substrate [1-2].

Design of Compact U-Slot Circular Patch Antenna on RT DUROID ... plane. Embedding a suitable U shaped slot in circular shape radiating patch is a very effective method for achieving a wide bandwidth. Several U-slot patch antennas has been reported recently to improve bandwidth [4-6]. In this paper U-slot is designed on circular patch to achieve more compactness and high impedance bandwidth. [updated!]U-slot on patch antenna for bandwidth enhancement Once i tried to etch a U-slot on a well matched bottom-fed antenna, the S11 result turned to be extremely bad. are there any guidelines for U-slot (or other shape of the slot) technique, which is used to enlarge the bandwidth of the patch antenna? A Dual-Band U-Slot PIFA Antenna with Ground Slit for RFID ...
width of the longer slot are 0.3cm and 0.05cm respectively. The length and width of the shorter slot are 0.1 and 0.05 respectively. The diameter of the feed is 0.05cm and the hieght is 0.16cm.The proposed antenna has three resonant modes and having a maximum gain of 8.4 Dbi. Design of U Slot Patch Antenna for Wi-max and Radar

What is the difference between slot antenna and patch antenna ... A patch antenna is literally a patch of metal or other conductor on a flat surface. There may or may not be a ground plane on the other side of the substrate. The directionality, gain, polarization, and impedance are a function of the size and shape, and placement of the feed line. Most GPSs use a patch antenna. BANDWIDTH ENHANCEMENT OF U- SLOT MICROSTRIP PATCH ANTENNA bandwidth of the designed U-slot microstrip patch antenna is enhanced by adjusting the U-slot dimensions and adding two shorting walls. Two modified designs are proposed to achieve a wide bandwidth operating in wideband communications. The first modified design is by increasing the U-slot
fabrication. The antenna return loss bandwidth is about 52.94%, centered about 3.4 GHz. The effect of the parameters, such as u slot length and width, on the ...
