<p>The printed monopole antenna having a printed circuit board (12) with a first side and a second side, a monopole radiating element comprising a first conductive trace (18) formed on the printed circuit board first side, and a conductive element comprising a second conductive trace (20) formed on the printed circuit board adjacent the first conductive trace. The second conductive trace (20) defines and extended ground plane which prevents the radiation of currents from that portion of the first conductive trace aligned with the second conductive trace. The second conductive trace may be formed on either side of the printed circuit board. The printed monopole antenna may be modified to operate within two separate frequency bandwidths.</p> |
