A single‐layer planar end‐fire circularly polarised microstrip antenna with enhanced bandwidth is proposed by loading with a metal pin. The original antenna is designed with a shorted parallel‐plate cavity that serves as a magnetic dipole, and a double‐sided printed bowtie dipole acts as an electric dipole. Then a metal pin is loaded connecting two metal surfaces and impedance bandwidth is improved obviously. One prototype is fabricated for verification and measured 19% –10 dB impedance bandwidth and 36% 3 dB axial ratio bandwidth are achieved.
