Abstract

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.

Claims

1. An antenna enhancing system for a portable radio transmitter, receiver or transceiver, comprising:

a. a conductive plate having a front surface and a back surface,

b. a conducting wire having a free end and an attached end, wherein the attached end is attached conductively to the front surface of the conductive plate, and the back surface of the conductive plate is located in close proximity to the portable radio transmitter, receiver or transceiver,

c. the conducting wire has a length in inches related to a frequency of transmission or reception of the portable radio transmitter, receiver or transceiver by a formula (146/Frequency in megahertz) times 22, + or −

20%.

2. A method for enhancing a signal transmitted to or from a radio, comprising the steps of:

a. positioning a plate in non-conducting proximity to a heat sink of the radio, and

b. conductively attaching a flexible wire to the plate, and

c. adjusting a length of the wire according to a formula relating the length of the wire in inches to a frequency of a transmission in megahertz,

whereby a radio signal is enhanced by 6 to 12 decibels.
