Patent ID: 8228250

Claim:
A composite antenna apparatus comprising: a first antenna element; a second antenna element; a rod member accommodating the first antenna element and the second antenna element therein; a circuit board; a base member accommodating the circuit board therein; and a connector mechanically coupling an end portion of the rod member and the base member so as to transmit a first signal received by the first antenna element and a second signal received by the second antenna element to the circuit board, the connector comprising: a first conductive member configured to transmit the first signal to the circuit board therethrough; and a second conductive member configured to transmit the second signal to the circuit board therethrough, wherein the connector comprises a first part provided on the end portion of the rod member and a second part provided on the base member and configured to be coupled with the first part, the first conductive member includes: a first inner conductive member provided in the first part and being concentric with an axis of the rod member; and a second inner conductive member provided in the second part and electrically connected to the first inner conductive member and the circuit board, and the second conductive member includes: a first outer conductive member provided in the first part, protruded from the end portion of the rod member, and covering the first inner conductive member; and a second outer conductive member, provided in the second part, configured to fit with the first outer conductive member, and electrically connected to the first outer conductive member and the circuit board, the second outer conductive member covering the second inner conductive member.
