Abstract
A broadband antenna belongs to the field of wireless communication. The traditional broadband antenna has problems of narrowness in the designed frequency band and incapability of being compatible to a high-frequency band communication transmission or radar system. The broadband antenna comprises a dielectric substrate (1), wherein a microstrip feeding line (2) and an oval adjustment branch (3) are printed on one side panel of the dielectric substrate (1), a metal patch (4) formed with an oval hole (5) is printed on the other side panel of the dielectric substrate (1), and an oval metal patch (6) is printed in the oval hole (5). The broadband antenna designed by the invention is in a frequency range of 2.48 to 28.63GHz, and the return loss is smaller than (-10) dB. The working frequency band of the antenna can cover frequencies of wireless communication, radar, navigation and section multi-point transmission service systems, and coordinative working of multiple types of systems is achieved. The antenna is of a printing structure and has the characteristics of low profile, a compact structure, light weight and low cost, and is easy to integrate.
