A 24 GHz end-fire helix antenna with high gain turn ratio in PCB technology

Abstract

A wideband end fire antenna architecture in planar technology with fewer turns: helix antenna in planar technology adopting thickness of quarter wavelength is suggested. A wideband 24 GHz helix antennas with 2.25 turns in rogers compressed RT 4350 technology is presented. The antenna has a bandwidth of 6.2 GHz for S11; gain of 9.3 dBi, half power width of 39.5° and 39° respectively in X-Z and X-Y plane. This helix antenna boasts of wide bandwidth, high gain, high half power width, compactness and high gain turn ratio. And it could also be utilized in antenna design for other frequency bands with compressed PCB technology, and as well for on-chip THz antenna design.
