A Wideband Corrugated Ridged Horn Antenna with Enhanced Gain and Stable Phase Center for X- and Ku-Band Applications
Abstract
In this letter, a structure and design procedure of a novel double-flared conical horn antenna with an improved gain and a stable phase center is presented. The antenna incorporates a hybrid ridged and corrugated structure. A double-ridged section is responsible for ensuring a wideband operation, whereas the corrugated section supports the hybrid mode. The antenna impedance bandwidth (VSWR < 2) is 6 GHz to 20 GHz. Excellent performance is demonstrated for both the X and Ku bands. In particular, the antenna exhibits 12 dBi to 18 dBi gain over both operating bands, a constant 44-degree, 10-dB beamwidth radiation pattern over the Ku band and a close-to-constant 65-degree beamwidth over the X band. The design is validated using both numerically and experimentally. The measurement and simulation indicate that the phase center variation in the X and the Ku bands is less than 2 cm and 1.5cm, respectively.
