A Waveguide-fed One-dimensional Bulleye Antenna

This paper presents a waveguide-fed one-dimensional bull-eye antenna, which innovatively combines a waveguide slot array antenna with a bull-eye antenna. The antenna array uses a simple bulleye structure and the feeding uses the waveguide slot antenna with a large power capacity. The simulation results show that the antenna has a high gain of 23dBi and a power capacity of 9MW at 1.9GHz. The antenna gain increases with the increase of the number of grooves of the bulleye antenna or the number of slots in the waveguide. The antenna has the features of high gain, low loss, high power capacity, low cost and easy conformation.
