Experimental investigations into a linearly polarized radial slot antenna for DBS TV in Australia

A Stable Design of Coaxial Adaptor for Radial Line Slot Antenna

“…An interest in using this antenna is growing because of its ease in manufacturing and lower loss [1]. Nowadays, this antenna finds different applications such as satellite TV reception Direct Broadcast System, DBS [2,5], local multiport distribution system (LMDS) [6] and Wireless LANs [7]. This design presented in this paper has better performance than many equivalent designs [8][9][10][11].…”

“…For example, to have RL below −30 dB, h 1 is between 5.5 mm and 5.8 mm (the variation is 0.3 mm) and h 2 is between 9.5 mm and 10 mm (the variation is 0.5 mm). But, for practical applications of feed adaptor in the RLSA antenna, h 2 must be about λ/4 (≈ 6 mm at 12.45 GHz) [1,4,5]. In the next sections, the method for increasing these variations is proposed.…”

Radial-line planar antenna with microstrip-feed coupling lines

“…Mainly, the developed applications have been implemented using radial-line slotted antennas (RLSAs) for linear [1,2] and circular [3][4][5] polarization. In both cases, the radial waveguide feeds a pair of slots placed according to the radial-line field characteristics.…”

Multilayered Cavity Material Radial Line Slot Array Antenna with Improved Bandwidth for 5G Communication Application

“…For grating lobes free radiation pattern, it was shown by (Davis & Bialkowski, 1997) that ɛ r must be greater than 1.0. More on the theory and design of RLSA antenna with linear polarization utilizing disk ended feed probe can be found in (Davis & Bialkowski, 1997;Takada et al, 1992).…”
