<p>A directional center-fed half wave dipole antenna is constructed from a multilayer substrate (100) having dipole antenna elements (112, 142) disposed on opposite surfaces (113, 141) of the multilayer substrate (100). An energy reflector (160) is disposed on at least one side of the substrate (100) and positioned adjacent to the dipole antenna elements (112, 142). The dipole antenna elements (112, 142) are fed by a center feed member(122). Center feed member (122) has a tapered width so as to provide the necessary impedance matching. A ground plane is disposed whithin the multilayer substrate, the elements of which (114, 134) are positioned on both sides of the center feed element (122).</p> |
