Millimeter Wave Radiator: Actively and Passively Excited Sinusoidal PCB Strip and Microstrip Antennas

Abstract

In this paper, the millimeter-wave radiation properties of actively and passively excited sinusoidal PCB strip and microstrip antennas are investigated. The main advantage of constructing PCB antennas is the reduction of antenna size comparing with the wire structures. The constructed antennas can be used as small-sized and frequency-sacnning antennas In millimeter wave radars.
