ANTENNA ASSEMBLY FOR SUBSURFACE METER PITS

摘要

An antenna assembly (10) for subsurface utility metering equipment includes a disk-shaped radiating element (50) which is connected through a wire (51) having a self-inductance to a capacitor (C) and then to a ground plane (41) and a connector (31) for a coaxial cable (30) to provide an LC circuit for impedance matching of the antenna assembly (10) to a transmitter.
