Broadband widebeamwidth printed dipole antenna

A high-efficiency microstrip-fed angled-dipole antenna has been developed. The printed dipole with an integrated balun features a broad operating bandwidth. The simulation of the antenna show that 7.4-10.5GHz band with VSWR less than 2 is obtained, and gain is more than 4.8dB. With choosing the proper dipole arms angle and with a radome, we can get the widest E-plane and H-plane beamwidth. Comparing the proposed antenna to the similar antennas, it has a simple structure and a high gain, also the E-plane and H-plane beamwidth can reach about 101° and 108°. Wide beamwidth and high gain is obtained, which satisfies the application of wireless communication.
