An Ultrabroadband Microstrip Detector up to 40 GHz

Abstract

Detectors designing is a key aspect for the development of the new millimeter wave systems. In this paper two detectors in microstrip technology are presented. They use zero bias Schottky diodes to detect signals from low frequency to 40 GHz. High sensibility, flat frequency response and ultrabroadband are the main features of these designs. They are also cheap and easy to mount because they have been built using microstrip technology. This paper explains most technological questions which must be taken into account to design such detectors.
