Patent ID: 7542001

Claim:
A dual broadband dipole array antenna comprising a grounding structure being a conductive hexagonal container, open at two opposite ends and comprising two parallel panels being conductive, being mounted parallelly to each other and each having a hole being centrally formed through the parallel panel; two connecting edges being formed opposite to each other; and two non-connecting edges; and four congruent panels being conductive, formed in pairs and each having two connecting edges; and two non-connecting edges; where pairs of the congruent panels are formed on and protrude respectively from the connecting edges of the parallel panels at an outer angle from the parallel to form an apex having an inner angle and are symmetrical with respect to each other; a circuit module being a transmitting antenna circuit module and having a circuit board being a printed circuit board and being phase reversible and having a front surface; a rear surface; and a metal layer being formed on the rear surface of the circuit board; a conductive wire being formed longitudinally on the front surface of the circuit board and heaving two ends and a connecting point, where a length difference between the connecting point to the ends forms a 180° phase difference for signals from the connecting point to the ends; an ohmic plug receiving signals from external signal sources and transmitting the signals to the circuit board and having an outer electrode being electrically connected to the metal layer of the circuit board; and an inner electrode partially plugging through the circuit board to electrically connect to the connecting point of the conductive wire; and two feeding wires being conductive and each having a length; a proximal end being connected one of the ends of the conductive wire; and a distal end being mounted through one of the holes of the parallel panels and isolating to the grounding structure; and two feeding boards being conductive, being connected respectively to the distal ends of the feeding wires and each comprises a triangular segment having a vertex being connected to the distal end of the corresponding feeding wire and having a vertex angle matching impedance for the signals sent from the circuit module to the triangular feeding boards; and a base edge being opposite to the vertex angle and having a length corresponding to a quarter of a wavelength of a center frequency of a primary operating band; and a quadrangular segment being conductive and formed on and protruding from the base edge of the corresponding triangular segment and each having two side edges; and a distal edge being opposite to the base edge of the triangular segment.
