  • Method and apparatus to quantify mast clamp current probe effective loss on pole-mast antenna
    Patent number: 8311752
    Abstract: A method for quantifying the effective loss of a mast-clamp-current-probe (MCCP) antenna comprising the following steps: providing a vector network analyzer (VNA) having first and second ports (Ports 1 and 2 respectively); coupling a transmit monopole antenna to Port 1 via a first transmission line; coupling a receive antenna to Port 2 via a second transmission line; determining the S-parameters of the two coupled antennas; calculating the power at the receive antenna (Pr); converting the transmit antenna to the MCCP antenna by shorting the transmit antenna to ground and clamping a current probe around the transmit antenna; determining the S?-parameters of the MCCP antenna and the receive antenna; calculating the power at the receive antenna (Pr?) when coupled to the MCCP antenna; and quantifying the effective loss of the MCCP antenna as the difference Pr?Pr?.
