When the rod bar is extended from the main body, the loop handle and the rod bar serve as a rod antenna. The rod bar moves in vertical direction along the interior of a connector(16) mounted at the main body of the radio communication equipment.

Description

Sliding annular antenna and single annular antenna of portable mobile radio communication device. {Slide system and Single end system of Loop antenna}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna of a portable mobile wireless communication device, and more particularly, to a loop antenna that implements an antenna capable of infiltrating or extending in and out of a body of a wireless communication device.

A structural diagram of a conventional portable mobile radio communication device is shown in FIGS. 1 and 2. 1 is a structure showing a state in which the rod antenna of the dual-structure antenna is immersed, Figure 2 is a structure showing a state in which the rod antenna of the dual-structure antenna is extended.

Looking at the configuration of a portable wireless communication device using a conventional dual-structure antenna as shown in Figures 1 and 2, a helical antenna (11) and a rod antenna (13) rod antenna (body 10) It is coupled by the cap 12 and the connector 16 on one side of the top. The helical antenna 11 spirally wraps the metallic antenna wire 20 on the inner surface of the cap 12 derived from the body 10 to form a coil structure, and inserts the coil structure. The helical antenna 11 is electrically conductive between the cap 12 and the connector 16. The ring 18 is interpolated so as to be in contact with the antenna line 20. On the protruding portion of the top of the rod antenna 13 is a knob 14 and a conductive stopper 19 is coupled to the bottom. In addition, the metallic antenna wire 20 is positioned at the center of the rod antenna 13, and the outer surface of the rod antenna 13 is formed of an insulating polyacetal material.

1 is a state in which a load antenna 13 is immersed in a body 10 of a wireless communication device having a conventional dual structure antenna, and flute 15 of the load antenna 13 is formed by the inner surface side of the cap 12. The helical antenna 11 functions as an antenna with the conductive ring 18 and the conductive stopper 19 being electrically uncontacted.

FIG. 2 is a state in which the body extends vertically upward from the body 10 of the conventional wireless communication device having a dual-structure antenna. The conductive ring 18 and the conductive stopper 19 are extended at the position where the conductive stopper 19 fixed to the lower end of the rod antenna 13 by the connector groove 17 and the conductive ring 18 is vertically extended. It is fixed to the elasticity of the rod antenna 13 to the electrical contact state by the metal to function as an antenna extended.

The dual-structure antenna of the conventional portable mobile radio communication device having the above-described structure is an antenna having a unique extension as it is miniaturized and developed to be portable to the radio communication device. This is a limiting factor to diversification, which limits the gain effect on radio transmission and reception resulting from the increase of the antenna length. The handle for extending the dual-structure antenna is smallly drawn over a part of the rod antenna, and the area that can be held by the cap and gap is small. Problems that are limited when rapid elongation is required. Physical friction caused by metal contact means due to mechanical deterioration of antenna function and immersion and elongation inside and outside the body due to the generation of electromagnetic waves that are unnecessary for the electrical connection of metal contacts during elongation. Contact area caused by wear Is a problem.

Therefore, an antenna having a dual antenna structure is a factor that causes the above problems.

For the purpose of the present invention, the convenience of extension and the ring shape fixed to the body by increasing the size by the ring-shaped handle that is easy to catch as a hook-shaped to protrude small to stretch the grip on the handle portion of the conventional rod antenna An object of the present invention is to provide a wired single ring antenna.

In another object of the present invention, the rod antenna of the conventional dual-structure antenna is the only antenna that is infiltrated and extended in and out of the body, and the antenna line is interpolated in the track of the inner surface of the slide-type annular antenna as a limiting factor in the linear length diversification. In order to provide an integrated annular antenna by increasing the antenna length and the antenna line in the track of the annular handle in the infiltrated state as a helical antenna function of the conventional dual structure antenna.

According to another object of the present invention, when the rod antenna is immersed in the conventional dual-structure antenna, the electromagnetic wave coupling between the lower feed part of the helical antenna portion and the submerged rod antenna when the rod antenna operates only in relation to the antenna line is related to the antenna line. The purpose of the present invention is to provide an effect of preventing this by always connecting the conductor to the contact portion of the circuit terminal fixed to the body in connection with the circuit.
