Abstract

Abstract In this paper it is aimed to design and develop a passive detector by employing a Schottky Barrier Diode (SBD) with zero bias. For this work a low cost commercially available Schottky barrier diode SMS7630-079LF is adopted. A compact multi stopband resonator has been incorporated to improve the sensitivity of the detector by attenuating the RF signal up to fourth harmonic at the detector output port. The entire module is based on microstrip circuit and consequently very easy and cheap to fabricate, which fulfils the low-cost necessities of radar system assembling. To validate this method, a prototype of the proposed detector is developed for 2.26 GHz, with a board size of 0.44λg x 0.36λg. The measured outcomes confirm the suppression of the fundamental signal frequency by nearly 23.8 dB along with other high order harmonic suppression.
