the two slots in-phase with nearly equal antenna currents. Thus, the patch operates as an array of two slots with a free-space separation somewhat less than λ/2. Maximum radiation is normal to the plane of the patch. Polarization is at right angles to the length of the slots, par-allel to the feedline orientation shown in Fig. 1. A Review- Microstrip Patch Antenna Design number of iterations, size of antenna decreases. By providing a number of slots over the patch, bandwidth is improved of patch antenna. Due to presence of multiple slots, Q factor decreases and value of patch inductance increases. By the decrease in Q factor, the bandwidth (BW) of patch antenna is increased accordingly, Bandwidth, BW [9] = 1 √2 Effect of Feed Position for Same E-Type Microstrip Patch ... slots in the patch which makes an E shape in the patch. E-shaped patch antenna can increases bandwidth above 30% compared to a regular rectangular patch antenna. Comparing both designs, the E-shaped is much simpler to construct by only adjusting length, width and position of slots.[9] Firstly we consider a rectangular patch antenna, than for ... Effect of Height on Edge Tapered Rectangular Patch Antenna ... (a) Simple patch antenna For simple patch effects of height of substrate h=1.57 , 1.59,1.6,2 mm has been shown below it has been found that the height of the substrate is increases their return loss also increases. Fig.3 Input reflection coefficient of simple rectangular patch antenna to show the effect of
bandwidth of 68MHZ, then the same antenna was converted to U -slot patch antenna which resulted into lower shift in frequency of operation at 2. 10GHz. This result shows an area reduction of antenna. The size of this slot antenna is lower than that of rectangular antenna. To improve the compact size of this antenna, modified U -slot

Design & Simulation of Double U-Slot Microstrip Patch Antenna ... Design & Simulation of Double U-Slot Microstrip. Patch Antenna for WiMAX Application. Md. Suaibur Rahman 1, Md. Munjure Mowla 2, Md. Mahabub Alam 3. Abstract — This paper presents the numerical simulation of double U-slots microstrip patch antenna for W iMAX application. The proposed antenna is feed by the Transmission line. EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA This paper presents effect of slots on microstrip patch antenna and its parameters. The effect is shown on bandwidth, gain, radiation pattern, return loss, axial ratio and size of an antenna. The slots on the patch or on the ground plane will help to design a antenna with improved bandwidth and effeciency. (PDF) Effects of Slot Loading on Microstrip Patch Antennas The slots of those antennas are loaded in symmetrical with respect to the edge of the patch. However, notch antenna is a form of slot antenna constituted by asymmetrical notching one side of the ...
