Embodiment Construction

[0016] The purpose of the present invention must be achieved by the following measures.

[0017] An embodiment of the present invention works in the frequency bands of 824-960 MHz and 1710-2500 MHz, but can also be used in other frequency bands.

[0018] Refer to Figure 1 to Figure 5.

[0019] The radiator 1 of the present invention is made of a copper clad laminate and formed by a printed circuit process. The inner conductor of the feeding microstrip line 3 and the feeding coaxial line 4 and the other arm of the symmetrical vibrator are electrically connected by welding. The reflector 2 is made of a metal material, and the reflector 2 is electrically connected to the symmetrical vibrator through the feed coaxial line 4 and the short-circuiter 6 through a welding process.

[0020] Although the present invention has been described with respect to one embodiment, it is not limited to the described embodiment, and various works made by professionals in the technical field without departi...

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 wideband antenna of a VHF / UHF frequency band radio system, in particular to a wideband symmetrical vibrator antenna shared by multiple networks and multiple channels in the fields of mobile communications, broadcasting and television. 【Background technique】 [0002] With the rapid development of mobile communication technology, today has entered an era where mobile communication networks with multiple technologies and multiple services coexist. The diversification of operators and the ability of one operator to operate multiple networks at the same time bring diversification to the public Mobile communication services such as GSM, CDMA, DCS, PHS, 3G, WLAN, etc. [0003] The coverage quality of mobile communication networks is the key to improving customer satisfaction. Network optimization and resolution of blind spot coverage are highly valued by operators. Under the premise of sufficient system capacity, repeaters and indoor si...
