Abstract
The dual-feed microstrip patch antenna is presented. This new radiator has broadband match and unidirectional azimuth pattern, desirable characteristics for use in broadband endfire arrays. Design, construction, and experimental results (realized gain, input impedance and far-field patterns) are given for a log-periodic array of dual-feed patches. An array with only ten elements has been demonstrated to operate at nearly constant gain over a 2:1 frequency band with a voltage standing-wave ratio (VSWR) of less than 2:1.<>
