Abstract

The invention provides a planar antenna folding bracket and belongs to the technical field of mechanism design. A base is a long plate structure. Through-holes are disposed on both sides of an elliptical disk in the long-axis direction. A link support is arranged in parallel with a tail planar motor base. The output shaft of a reduction motor passes through a shaft hole and is connected with the right-angle shaft of the first link through a coupling. The first link is a rectangular bar member folded inwards twice and has a front end hinged to the tail end of a second link. The front end of thesecond link is hinged to the tail end of a third link. The rotation shaft of a first plate support is hinged to the through hole on the middle section of the first link. The outer arc edge of a fan-like first planar antenna is fixedly connected to the first plate support. A left half hinge is arranged on a junction of the right straight edge of the first planar antenna and the arc edge. A right half hinge is arranged on a junction of the left straight edge of the second planar antenna and the arc edge. The third link is a structure folded inwards once and has a front end provided with a fixedsecond plate support. The tail end of the third link and the front end of the second link are hinged through the end portion of a support rod.

Description

technical field [0001] The invention belongs to the technical field of mechanism design. Background technique [0002] Although most areas in the world now have strong signal coverage, it is more difficult to receive satellite signals in sparsely populated areas such as deserts, snow-capped mountains, and virgin forests. People trapped in these areas are less likely to successfully seek help from the outside world through communication devices such as mobile phones. If a plate antenna is used to receive signals, this can greatly increase the possibility of rescue. The plate antenna has the advantages of high gain, good sector pattern, small rear lobe, reliable sealing performance and long service life, and is widely used for outdoor signal propagation. [0003] There are a lot of researches on the plate antenna, most of them use electrical and control methods to enhance the performance of the antenna or other issues, but none of them involve enhancing the receiving performa...
