Abstract
A broad band impedance matching system and method for use with low-profile antennas. The system comprises an antenna formed by a pair of radiating elements positioned on or in proximity to the earth's surface. The antenna has an effective electrical length equal to one half wavelength in a given medium at the lowest frequency in a desired operating range of electromagnetic signal frequencies. Each antenna is preferably electrically insulated throughout its length. Each radiating element of the antenna system is connected to a transmission line so as to match the average magnitude of the impedance of the antenna over the desired operating range of electromagnetic signal frequencies to the impedance of the transmission line. Broad band antenna system performance may be further enhanced by configuring each radiating element such that it has two conductive arms which are joined at one end so as to be parallel or so as to form an acute angle of approximately ten degrees or less.
