In this paper, the effect of placing a reflecting sheet at the back of the probe fed slotted hexagonal patch antenna is presented. It is shown that the proposed antenna provides 128% ultr Fig mic 588 fin line basa wide band bandwidth with minimum back lobe. Effect of the Different Shapes: Aperture Coupled Abstract: The paper reviews the effect of the different shapes on the aperture coupled microstrip slot antenna. Aperture coupled microstrip slot antenna couples the patch antenna with microstripline through an aperture. One effective way to increase the impedance band-width is to change the patch shape, feed shape and the slot shape. The Fundamentals of Patch Antenna Design and … 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…
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

2. Antenna Design Architecture. The geometry of the proposed wide-slot defected ground structure antenna is portrayed in Figure 1.The antenna consists of simple wide square slot in the centre of one side of the substrate and fed line is printed on the other side for exciting two modes with close resonance frequency.
Effect of Antenna Size on Gain, Bandwidth, and Efficiencyl Roger F. Harrington 2 (June 29, 1959) A theoretical analysis is made of the effect of antenna size on parameters such as gain, bandwidth, and efficiency. Both near-zone and far-zone directive gains are considered. It Wideband Bow-Tie Slot Antenna With Tuning Stubs WIDEBAND BOW-TIE SLOT ANTENNA WITH TUNING STUBS Abdelnasser A. Eldek, Atef Z.
