Abstract

A deceleration module for extending or retracting a whip antenna. In the deceleration module, a motor unit is installed on the bottom of a body housing, a deceleration unit reduces a rotating force provided coaxially from the motor unit at least twice. A roller unit is integrally formed coaxially with the deceleration module by injection molding, and disposed to roll in an extending and retracting direction of the whip antenna in contact with the outer circumference of the whip antenna.

Description

technical field [0001] The present invention generally relates to an antenna device for a portable terminal, in particular to a deceleration module combined with a rotating device, which provides force to automatically retract a whip antenna, and reduces the rotational speed of a driving motor, and a deceleration module using the deceleration module Automatic antenna extension system. Background technique [0002] Generally, a cellular phone is a portable terminal capable of wirelessly communicating with a counterpart through a wireless communication system or base station. Such portable terminals are generally equipped with an antenna device that converts RF (Radio Frequency) energy received from a transmitter into electromagnetic energy and radiates it into the air, and receives electromagnetic energy from the air and transmits electric power to a receiver. [0003] Antenna devices generally include rod whip antennas and helical antennas, wherein the rod whip antenna is t...
