Embodiment Construction

[0022] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0023] Such as figure 1 with figure 2 As shown, a helical antenna in the UHF frequency band includes a plurality of reflectors 1, bottom antenna 2, top antenna 3 and adapter plate 4; the bottom of the top antenna 3 and the top of the bottom antenna 2 are detachable Connection, the bottom of the bottom antenna 2 is detachably connected to a plurality of reflectors 1, and an adapter plate 4 is also connected to the bottom of the bottom antenna 2 by screws.

[0024] Such as image 3 As shown, the plurality of reflectors 1 form a circle and are connected to the bottom of the bottom antenna 2 through positioning pins 23, and each reflector 1 is drilled with regular hexagonal through holes arranged in an orderly manner.

[0025] The shapes fo...

Abstract

The invention discloses a UHF band spiral antenna, and belongs to the technical field of wireless communication. The antenna comprises a plurality of reflection plates, a bottom end antenna, a top end antenna, and an adapter plate. The bottom end of the top end antenna is detachably connected with the top end of the bottom end antenna, and the bottom end of the bottom end antenna is detachably connected with the plurality of reflection plates. The bottom of the bottom end antenna is also connected with the adapter plate through a screw. The antenna can achieve the receiving of all wireless signals at the UHF band, is wide in receiving range of wireless signals, avoids the signal loss, can be folded or disassembled in real time, and is portable.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a helical antenna in the UHF frequency band. Background technique [0002] helical antenna (helical antenna) An antenna with a helical shape. It consists of a metal helix with good electrical conductivity, and is usually fed by a coaxial line. The core wire of the coaxial line is connected to one end of the helical line, and the outer conductor of the coaxial line is connected to the grounded metal mesh (or plate). connect. The radiation direction of the helical antenna is related to the circumference of the helix. When the circumference of the helix is ​​much smaller than one wavelength, the direction of the strongest radiation is perpendicular to the helix axis; when the circumference of the helix is ​​on the order of one wavelength, the strongest radiation appears in the direction of the helix axis. [0003] Ultra High Frequency (UHF) refers to radio waves wi...
