ANTENNA CONNECTOR FOR RADIO COMMUNICATION EQUIPMENT

摘要

An antenna connector for radio communication equipment is disclosed. The above connector converts the conventional parallel resonance of an antenna into a series resonance by forming a flat cutout portion on its impedance transformer, or the signal feed part for the antenna, without changing the characteristics of the antenna, thus broadening the bandwidth of the antenna. The connector is also designed to control or broaden the bandwidth of the antenna in accordance with the structure of the impedance transformer. The connector of this invention easily and simply controls the bandwidth of an antenna by changing the size and height of the impedance transformer, by changing the surface area of the cutout portion of the impedance transformer, or by changing the number of turns of the antenna fitted over the impedance transformer. Therefore, the connector is effectively used at various frequencies, and effectively and quickly meets a variation of the central frequency of an antenna with the variation being caused by a change in environmental conditions of the antenna.
