On the Use of Slots in the Design of Patch Antennas How I got into patch antenna research 2. Basic geometry and basic characteristics of patch antennas 3. Our first topic Patch Antenna The antenna bandwidth is governed by the impedance bandwidth (SWR 2), which is typically 2-3% for the basic geometry. ... The U-slot patch (Huynh and Lee, 1995; ... U-Slot Patch Antenna for Broadband Wireless Communications U-Slot Patch Antenna for Broadband Wireless Communications M.A. MATIN Department of Computer Science and Engineering BRAC University 66, Mohakhali, Dhaka -1212 BANGLADESH Abstract: - In this paper, a single patch wideband microstrip antenna resonating at 4.5 GHz is presented and the simulation results of its performance are reported.
U-slotted patch, the slots are embedded to the rectangular patch. Where, L and W are the length and width of the patch. ε r is the dielectric constant, ∆L is the length due to the fringing field .The fringing fields along the width can be model as radiating slots and electrically the patch of the micro strip antenna looks greater than
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 ENHANCEMENT OF BANDWIDTH OF RECTANGULAR PATCH ANTENNA USING ... decrease the size of the antenna [7, 14] and to improve the bandwidth of the antenna [8, 9, 15]. Handset antenna has been reported with wide bandwidth [10]. Half U-slot patch antenna with shorting wall reported in [11] with 28% impedance bandwidth. In this paper, broadband patch antenna with two square slots across its side surface is proposed ... Analysis and design of broad-band single-layer rectangular U ... A wide operating bandwidth for a single-layer coaxially fed rectangular microstrip patch antenna can be obtained by cutting a U-shaped slot on the patch. 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.

A compact microstrip patch antenna with improved bandwidth is proposed in this paper for applications in wireless communication.
tively. The U- slot patch antenna is designed for increasing the bandwidth and return loss but gain cannot increase. If array of the U- slot patch antenna is used then the gain can be im-proved. Therefore, the antenna will be better work in the Wi-MAX applications and wireless communication s system.
