Embodiment Construction

[0059] In order to further illustrate the method of the present invention, now describe in detail in conjunction with a preferred embodiment of the present invention shown in the accompanying drawings, but said embodiment is only for illustration and explanation purposes, can not be used to limit the patent protection scope of the present invention .

[0060] Such as Figure 1 to Figure 7 As shown, the method of 450MHz antenna fabrication is implemented.

[0061] The method comprises the steps of:

[0062] A. First prepare an antenna reflector 1 whose size is 272~276mm×272~276mm×0.5mm;

[0063] B. Then, on a diagonal line of the antenna reflector 1, the first feed A sheet 11 and the second feed A sheet 12 are arranged symmetrically with the center, and the fronts of the two feed A sheets are 91-95 mm apart; The first feed A piece 11 below the board 1 is insulated from the antenna reflector 1, and it is connected with the antenna lead through the first feeder board 13;

Abstract

Discloses are a 450-MHz antenna manufacturing method and a 450-MHz antenna device. The method comprises setting a first feed piece A and a second feed piece A on one of the diagonals of an antenna reflecting plate in a centrosymmetric mode, wherein the distance between the front edges of the two feed pieces A is 91-95 mm; setting a first feed piece B and a second feed piece B on the other diagonal of the antenna reflecting plate in the centrosymmetric mode, wherein the distance between the two feed pieces B is 91-95 mm; covering the feed pieces with a guide plate which is spaced from the top ends of the feed pieces at a distance of 6-10 mm; covering the guide plate with an antenna cover which is made of plastic materials. Compared with the prior art, the 450-MHz antenna device has the advantage of having a small size of 280 mm*280 mm, being excellent in performance and achieving stable transmission and receiving with a range of 50 m.

Description

technical field [0001] The present invention relates to antennas, in particular to a manufacturing method and antenna device for a 450MHz antenna. Background technique [0002] In the prior art, there are already methods and antenna devices for manufacturing 450MHz antennas, but the size of the antenna is large, generally 500mm×500mm. In some special occasions, the antenna of this size cannot be installed in the cabinet, and the size of the 450MHz antenna is reduced. Faced with many difficulties, after a lot of experiments, it was found that reducing the size of the 450MHz antenna by 10 centimeters requires a lot of experiments to find the best shape of the feed terminal. [0003] Moreover, the performance of the 450MHz antenna in the prior art is poor, and when the transmission distance is above 10M, the signal is intermittent and cannot be used. [0004] People are looking forward to a 450MHz antenna with small size and excellent performance for industrial control. [00...
