eRx2¡eRx1. The taper length, L is x2 ¡ x1 and the aperture height is H is 2(y2 ¡ y1) + WSL. In the limiting case where R approaches zero, the exponential taper results in a so-called linearly tapered slot antenna (LTSA) for which the taper slope is constant and given by s0 = (y2 ¡ y1)=(x2 ¡ x1). Implementation of rectangular slit-inserted ultra-wideband Aug 22, 2016 · Abstract. The rectangular slit-inserted tapered slot antenna operated at a bandwidth of 8.45 GHz, and the bandwidth improved upon the basic tapered slot antenna by 4.72 GHz. The radiation pattern of the antenna was suitable for location recognition in a certain direction owing to an appropriate 3 dB beam width. US7642981B2 - Wide-band slot antenna apparatus with As described above, the unbalanced-feed wideband slot antenna apparatus of the present invention not only can achieve a wideband operation which is difficult for prior art slot antenna apparatuses to achieve, but also can maintain a main beam direction across an operating band, and suppress undesired variations in half-width of a main beam in

Slot antennas are popular omnidirectional microwave antennas. These antennas feature omnidirectional gain around the azimuth with horizontal polarization. Waveguide slot antennas, usually with an array of slots for higher gain like Figure. 7-1, are used at frequencies from 2 to 24 GHz, while...

The design of hexagonal shaped patch antenna with a narrow slot for wireless local area network (WLAN) is reported here. The slot oriented at 45 0 , in order to achieve left-hand circular polarization (LHCP).
