Abstract :
A novel type of antenna-coupled infrared detector consisting of a niobium microbolometer integrated with two microstrip patch antennas is reported. This is the first microstrip antenna structure proven to detect thermal infrared radiation. A polarisation ratio of >20:1 and a time constant of <150 ns have been measured for this type of detector
