Linearly polarised radial line slot antenna for highpower.

A linearly polarized radial line patch antenna with internal coupling patches is presented. A non-resonant antenna structure has been designed, with a 0.68 lt;subgt;0lt;/subgt; radial spacing between. This article presents a method to produce a highly directive circularly polarized radiation beam gaingt;35 dBi from an all-metal circularly polarized radial-line slot array RLSA antenna. A radial and narrow slot in the ground plane provides coupling between the L-shaped feedline and circular ring slot. The circular polarization is realized by implementing the slits perturbation located diagonally to perturb the current flow on the slot structure. The antenna prototype is fabricated on FR4 substrate.

Abstract and Figures. This article presents a wide band linearly polarized beam squinted radial line slot array RLSA antenna at 5.8GHz band. The open ended air gap technique was used to. But in linearly polarized LP RLSA antenna slots are arranged with a spacing of half-guided wavelength in the radial direc- tion, producing greater reflections from adjacent slot pairs that add in phase at the input feed point. Higher reflections create a very poor return loss performance in LP RLSA antenna [2], [4].
