Antenna oscillator

Abstract

An antenna oscillator comprises four vertical support sheets, two oscillator arms and one grounding lug, the four vertical support sheets are arranged to form a rectangle in a face to face manner, theupper portions of the four vertical support sheets are fixed via a first plastic fixed part, the lower portions of the four vertical support sheets are fixed via a second plastic fixed part, and eachplastic fixed part is provided with slots into which corresponding ends of the four vertical support sheets are inserted, the upper ends of the four vertical support sheets extend out of the slots ofthe first plastic fixed part respectively, every two vertical support sheets facing each other are connected with an elongated oscillator arm, the two elongated oscillator arms are arranged in a crossing manner, and the lower ends of the four vertical support sheets extend out of the slots of the second plastic fixed part and are connected with the grounding lug. The antenna oscillator is low inweight and cost, high in stability and reliability, and has a high popularization and application value.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to an antenna element. Background technique [0002] In the existing communication technology, a large number of criss-cross elements are used in the antenna array. Usually, the arms of the criss-cross elements are supported by sheet metal parts, and then the sheet metal parts are fixed on the reflector with screws, and finally the feeder is welded. Since the sheet metal support itself is in production, it is difficult to ensure the consistency of size and shape among multiple products, and deformation often occurs in the sheet metal support during transportation, resulting in cumbersome assembly of the antenna and poor structural strength , affecting the use of the antenna. In addition, such a criss-cross array is heavy in weight and high in manufacturing cost, which is not suitable for the development trend of low-cost and automated production in the communication ...
