Why we use Microstrip Patch Antennas ? Used for some reasons: Flat surface makes them ideal for mounting on airplane Impedance matching fairly simple Microstrip patch antennas have a very high antenna quality factor(Q). Q represents the losses associated with the antenna and a large Q leads to narrow bandwidthand low efficiency. Q can be ... Microstrip Antenna ppt | Antenna (Radio) (235 views) Optimization of Microstrip Fed Antenna. The return loss LR of the microstrip patch is given by LR = 20 Log (1/rf) , where rf is the reflection co-efficient given by rf =( Rin -50)/(Rin + 50). From the transmission line model it can be shown that the input resistance of a patch antenna at resonant frequency is given by: 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.

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 On the Use of Slots in the Design of Patch Antennas experimental study of the geometry shown in Fig.2.6. A patch antenna with a parasitic patch is sometimes known as an electromagnetically coupled patch antenna. The experiment was performed at NASA Lewis Research Center (later renamed Glenn Research Center) by my MS student J. Bobinchak, in collaboration with Dr. R. Q. Lee of NASA. PPT – Overview of Microstrip Antennas PowerPoint presentation ... Improving Bandwidth U-shaped slot The introduction of a U-shaped slot can give a significant bandwidth (10-40). (This is partly due to a double resonance effect.) Single Layer Single Patch Wideband Microstrip Antenna, T. Huynh and K. F.
