The RLSA antenna is fed by an aperture ... Beam-steerable radial-line slot antenna array | Request… A radial line slot antenna (RLSA) is a slotted waveguide planar array proposed for DBS subscriber antennas.These planar arrays consist of a transmission line in the form of a radial waveguide whose upper plate contains annular groups of linear slots. Dual Linearly Polarized Single-Layer Radial-Line Slot-… The applications of radial line slot antennas are satellite communication antenna, plasma etching, and high power use.The isolation between two slot arrays is also investigated in terms of the relative displacement along the radiation waveguide axis in the interdigital structure.

Radial Microstrip Slotline Feed Network for Circular
the conductor loss of conventional microstrip line is high (ref. 1) and consequently the feed network loss of patch antenna arrays is also high. The high loss lowers the array efficiency (rel_. 2 and 3), and in addition lowers the G/T ratio in a receiving array. Recently a radial line slot antenna array has been demonstrated to have high gain ... Influence of the Finite Slot Thickness on RLSA Antenna Design In this communication, we consider the effect of the thickness of the plate where slots are cut into, with reference to the design of a radial line slot array antenna. We show that the zero-thickness approximation results in a significant lack of accuracy even though the slot thickness is of the order of one-thirtieth of the wavelength. A high gain radial line slot array antenna for satellite ... The antenna has a wide impedance matching, with return loss greater than 10 dB over the operating frequency band from 20 GHz to 22 GHz (9.52%). The overall efficiency of the antenna is greater than 93%.
