This paper presents a new small circularly-polarized (CP) antenna element composed by a microstrip ring patch (MRP) and a vertical ring patch (VPA). With the combination of these two types of patch antennas, the proposed antenna finds a significant enhancement in the axial ratio bandwidth as well as the impedance bandwidth with employing a single coaxial excitation only. The antenna yields an impedance bandwidth of 4.5 %, an axial ratio bandwidth of 1.1% and the maximum gain of 4dBi with a stable broadside radiation pattern across the operating bandwidth. |
