ANTENNA APPARATUS AND WIRELESS COMMUNICATION APPARATUS
First Claim
1. An antenna apparatus, comprising:
- a leaky coaxial cable;
an superposing circuit configured to superpose a high frequency signal with a direct-current voltage and supply a transmission signal as the superposition result to the first end of the leaky coaxial cable;
a separation circuit that is connected with the second end of the leaky coaxial cable and separates the high frequency signal and the direct-current voltage from the transmission signal transmitted through the leaky coaxial cable;
a terminator configured to terminate the high frequency signal separated by the separation circuit; and
an electrical apparatus that is arranged nearby the second end of the leaky coaxial cable and is actuated by the direct-current voltage separated by the separation circuit.
