Analysis of Helical Antenna for Wireless Application at UHF

Abstract

A helix antenna serves as an electromagnetic emitter that transmits signals in the shape of a coiled thread. It possesses two primary operational modes: normal and axial. In the axial mode, radiation peaks along the helix's axis, creating a near-circular concentration of electromagnetic waves. This paper delves into the intricacies of designing a spiral antenna optimized for operation at a 3 GHz reverberative frequency. It exhibits indirect polarization and is ideally suited for wireless communications, facilitating the transmission and reception of VHF waves, especially for ionospheric propagation. The versatility of this antenna extends to various applications, including radio astronomy, space telemetry, satellites, and space-based communication systems. The proposed antenna design showcases a directional radiation pattern with a notable gain of 13.8 dB. Future research will explore its adaptability for deployment in aquatic environments, expanding its utility in scenarios that demand reliable wireless connectivity beneath the surface. This innovation holds great promise for enhancing communication capabilities across a range of fields and environments.
