Abstract
Logging while drilling (LWD) sensor coils (a.k.a. antennas) of LWD resistivity tools require impedance matching to a specified value to ensure power matching to the transmitter electronics or noise matching to the receiver electronics. Another important parameter to be considered is the common-mode rejection of the matching network to suppress common-mode signals from both the internal transmitter coil (antenna) as well as common-mode interference from other sources such as power supplies.
