The invention provides a low-profile unidirectional radiation differential ultra-wideband antenna. The antenna of the field of wireless communication comprises a bidirectional radiation differential ultra-wideband antenna and a packaging cavity. The bidirectional radiation differential ultra-wideband antenna comprises a left feed patch, a right feed patch, a rectangular dielectric substrate and agrounding plate. The packaging cavity comprises a packaging ground, a short circuit via hole, a radiation edge shielding via hole, a non-radiation edge shielding via hole, a shielding metal tape, an impedance matching via hole and an impedance matching circular plate. The upper end of the packaging cavity is connected with the grounding plate, and the lower end is connected with the packaging ground. The lower ends of the radiation edge and non-radiation edge shielding via holes are connected on the packaging ground, and the upper ends are suspended. The impedance matching via hole is arrangedin the packaging cavity, the lower end is connected with the packaging ground and the upper end is suspended. The shielding via hole and the shielding metal tape are additionally arranged on the radiation edge and the non-radiation edge so that unidirectional radiation of the antenna can be realized, and the ultra-wideband working of the antenna can also be realized. The height of the whole packaging cavity is 1 / 10 of the wavelength at the lowest working frequency so that the height of the whole antenna can be greatly reduced and the volume of the antenna can be reduced.
Description
technical field [0001] The invention relates to an antenna in the field of wireless communication, in particular to a low-profile unidirectional radiation differential ultra-wideband antenna. Background technique [0002] With the rapid development of wireless communication, global positioning system, satellite communication, personal communication and other communication systems put forward higher requirements for the broadband and miniaturization of the antenna. Ultra Wide Band (UWB) communication technology is widely used in communication, radar and military due to its advantages of large bandwidth, high transmission rate, strong anti-interference and strong anti-multipath ability. [0003] In recent years, many scholars have proposed a variety of UWB antennas, such as differential UWB antennas with a single-layer structure (Liang Lu,, et al., "Single‐layer differential CPW‐FED UWB antenna with common‐mode suppressed and band notched applications " , "Microwave & Optical...
