Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0027] refer to figure 1 , the invention provides a retractable external antenna. The antenna radiator is several spiral metal lines, and the metal lines are on a flexible printed circuit board FPC. For example, exemplary, the antenna is rolled into a cylinder with an outer diameter of about 11 mm and a length of about 85 mm (FPC cylinder for short).

[0028] Such as figure 2 One end of the FPC cylinder is welded on a PCB with an IC chip, and one side of the PCB is welded with an SMA connector; the ...

Abstract

The invention provides a telescopic external antenna. The antenna comprises a telescopic sleeve with a hollow interior; at least one radiating body is arranged in the sleeve; one end of the at least one radiating body is welded on a PCB with an IC chip; and the IC chip is connected with an SMA connector, and the SMA connector is fixedly arranged at the end part of the sleeve.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a retractable external antenna. Background technique [0002] The external antenna of mobile communication equipment for outdoor use requires a certain degree of waterproof and drop resistance. The external dimensions are mainly determined by the working frequency band. Some external antennas have a telescopic function, which means that the antenna can be stretched to a long shape to receive and transmit radio with better performance. Signals can also be compressed from the long dimension shape to the short dimension shape, where it stands by to receive radio signals. [0003] The existing retractable external antenna includes a fixed component and a movable component. The metal radiator used by the antenna to send and receive radio signals is a helical coil and a straight metal wire. The helical coil is in the fixed component, and the straight metal wire is in the movable component; The...
