Miniaturized Circularly Polarized Horn Antenna with a Single-Arm Spiral Structure for X-band
a miniature circularly polarized horn antenna is designed and implemented. The radiation part of the antenna is a single-arm spiral (SAS) structure, which is directly fed by 50Ω coaxial line through a small disc/ground-plane, and this feeding method replaces the traditional balun which often used in conventional two-arm balanced-mode spiral antenna. The gain of the antenna is increased by the back cavity and the conical horn, the beam width is controlled, and the phenomenon of beam pointing deviation is improved. It is revealed that the designed antenna has a good circularly polarized (CP) radiation performance over a design frequency range of 8 GHz to 12 GHz, and the overall dimension of the antenna is 40×40×24mm.
