Abstract

A new printed helical antenna (PHA) for a circularly polarized (CP) titled beam is proposed. With the introduction of a multiple sections technique into the PHA's helical arm, the antenna radiates a CP titled beam. To feed the antenna, a matching network composed of a 50 Ω microstrip transmission line and two symmetrical λ₀/8 open stubs is designed. The simulated and measured results show that the PHA radiates a CP tilted beam with a maximum radiation direction of (θ_max, φ_max) = (32°, 135°) at f₀ = 2.11 GHz. The measured bandwidth with a reflection coefficient lower than −10 dB is 11.8% (1.99-2.24 GHz), and the experimental results for the radiation pattern, gain, and axial ratio (AR) are also presented.
