A novel compact monopole antenna with wide circularly polarised (CP) bandwidth is designed, fabricated and measured. The wide impedance bandwidth and broadband CP characteristic are achieved based on a simple tilted monopole structure, which consists of a slotted rectangular patch and an improved ground plane. The measured impedance bandwidth with return loss better than 10 dB is 97.4% (1.10–3.19 GHz), the measured 3 dB axial‐ratio bandwidth is 59.1% (1.11–2.04 GHz) and the measured peak gain within the operating band is 4.84 dBic, which indicates that it is a good candidate for the application of various global navigation satellite systems.
