Portable radio antenna enhancement using non-contacting device

摘要

An antenna enhancement system for portable radio transceivers includes a radio conductive plate 10 held in proximity to the back of the transceiver 26. Attached to the plate is a dangling wire 18 whose length bears a relationship to the frequency of transmission. This length is determined experimentally. The system increases the effectiveness of the existing antenna by 6 to 12 decibels.
