Abstract:
Time domain radar signals are transmitted and received from vee dipole antennas on circuit boards. The antennas are formed by spaced deposited copper pads and discrete surface mount resistors soldered between the copper pads. The antenna feed-points are connected directly to adjacent transmitting and receiving circuits on the same printed circuit board. Traces are printed on a middle layer of a strip of printed circuit board. Vias connect ground planes on opposite sides. Artifacts are reduced, and signal properties are controlled.
