Abstract

The invention discloses a wide-band antenna with the feature of being easy to install. The wide-band antenna with the feature of being easy to install comprises a dielectric substrate and two pairs of signal metal boards upright arranged on the upper surface of the dielectric substrate, wherein the two pairs of signal metal boards are in bilateral symmetry to form a pair of dipoles; a pair of metal floors is arranged between the pair of signal metal boards on the left and the upper surface of the dielectric substrate; a signal metal block is arranged between the pair of signal metal boards on the right and the upper surface of the dielectric substrate; the signal metal block fixes the pair of signal metal boards on the right; the metal floors include the first metal floor and the second metal floor; the upper surface of the dielectric substrate is further provided with a signal metal strip; the signal metal strip is located between the first metal floor and the second metal floor and is connected with the signal metal block to form a feed structure. The wide-band antenna is simple in structure, low in cost, easy to machine, small in size, wide in frequency band and capable of being applied to LTE mobile phone base stations of 1.75-2.7 Ghz.

Description

technical field [0001] The invention relates to a broadband antenna, in particular to a broadband antenna capable of easy installation, and belongs to the field of wireless communication. Background technique [0002] With the increasing popularity of wireless transmission products, users can use wireless transmission devices to transmit or receive data and information without being restricted by the environment. For wireless transmission devices, whether it is a personal digital assistant, a mobile phone or a notebook computer, etc. , the antenna is a very important component in the wireless transmission device, because the quality of the antenna has a considerable impact on the quality of wireless transmission and reception. [0003] As one of the core equipment to achieve mobile communication network coverage, the base station antenna is an important part of the mobile communication system, directly determines the coverage and signal transmission of the base station netwo...
