Abstract

This invention discloses a broadband symmetrical vibrator antenna different from that of ordinary structures composed of a radiator, a reflector, a supply micro-strip wire, a supply coaxial wire, a parasitic unit and a short circuit device characterizing in utilizing an arm of a plane symmetrical vibrator to constitute an earth surface of the supply micro-strip wire and the coaxial wire to realize broadband balanced supply, which has fine matched property in 2-3 frequency multiplications suitable for VHF/UHF bands, especially for the broadband array antennas with reflectors.

Description

【Technical field】 [0001] The invention relates to a broadband antenna of a VHF / UHF frequency band radio system, in particular to a broadband symmetrical dipole antenna shared by multiple networks and multiple channels in the fields of mobile communication, radio and television, etc. 【Background technique】 [0002] With the rapid development of mobile communication technology, today has entered the era of coexistence of mobile communication networks with multiple technologies and services. The diversification of operators and the fact that one operator can operate multiple networks at the same time bring diversity to the public. Mobile communication services, such as GSM, CDMA, DCS, PHS, 3G, WLAN, etc. [0003] The coverage quality of the mobile communication network is the key to improving customer satisfaction, and operators attach great importance to network optimization and solving blind spot coverage. On the premise that the system capacity is sufficient, repeaters and ...
