Embodiment Construction

[0038] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0039] refer to figure 1 As shown, the radiating unit of an ultra-wideband antenna of the present invention is a single-polarized radiating unit, including a pair of two unit arms 21a, 21b, two pairs of four support members 31a, 31b, 31c, 31d, A feeder 41 , and a reflector 11 .

[0040] The reflector 11 constitutes the reflector of the radiation unit, on which the supports 31a, 31b, 31c, 31d and the feeder 41 are installed, figure 1 The cross-section of the reflector 11 shown is roughly U-shaped, and it has a sheet part 11a for installing the supports 31a-31d and the feeder 41, and folded folds from both sides of the sheet part 11a. Exit 11b.

[0041]The pair of unit arms 21a, 21b adopts a plane geometry with a three-dimensional structure, and its shape is a plane square structure, which is made of a metal plate. Since the two unit arms 21a, 21b are arrang...

Abstract

The invention relates to an ultra-wide band antenna and single-polarized and dual-polarized radiating elements thereof. The dual-polarized radiating element is formed on the basis of orthogonality of two pairs of single-polarized radiating elements, wherein each single-polarized radiating element is used for transmitting and receiving a single polarized signal and comprises a reflecting plate, a pair of element arms and a feed member, the reflecting plate constitutes a reflector of the radiating element, the pair of element arms constitute a half-wave symmetrical dipole, the feed member is fixed on the reflecting plate, and a circuit for feeding the element arms is manufactured on the feed member; and each element arm is connected with the reflecting plate by at least two supporting members so as to maintain the relative positional relationship, and non-conducting media separated capacitive coupling is formed among the supporting members. The radiating elements and the ultra-wide band antenna thereof have simple structure and low manufacturing cost and can obtain good wideband characteristics.

Description

【Technical field】 [0001] The invention relates to the field of mobile communication antennas, in particular to an ultra-wideband antenna and a single-polarization and dual-polarization radiation unit thereof. 【technical background】 [0002] In recent years, with the construction and operation of the third-generation mobile communication network, and the wide application of broadband wireless networks such as WLAN and WiMax, the market has put forward a huge demand for broadband communication base station antennas. For example, antennas in the frequency band of 1.7GHz to 2.7GHz cover the following communication standards: GSM1800, CDMA 1900, IMT-2000, TD-CDMA, WLAN, WiMax, etc. The development and complementarity of communication technologies, and the differentiation of customer needs have resulted in the situation of multi-system coexistence and increased frequency bands. [0003] Due to the public's deep understanding of the impact of electromagnetic radiation on self-heal...
