A Printed Helical Circular Polarization Antenna for GNSS Anti-Attacking System

Abstract

This paper presents a new configuration of a printed helical circular polarization antenna with a rectangular cross-section to emit an end-fire beam. The antenna is designed for anti-attacking systems that work against attackers guided by global navigation satellite systems. It has the ability to handle a peak power up to 696.3 kW. The antenna achieves a wide impedance bandwidth and 3-dB axial ratio bandwidth range from 1.13 GHz to 1.7 GHz covering the whole global navigation satellite systems frequency band. The antenna has a stable gain of 6.4 dBic across the whole frequency band. It has a low profile of $0.7\lambda_{0}$. The antenna small size, low cost, simple structure, high power handling capabilities and good performance make it suitable for anti-attacking systems.
