Receiving properties of slot antenna coupled warm carrier device were discussed. Since the sensitivity of the detector strongly depends on the antenna gain, it is important to improve the power gain of the antenna. In the case of the slot antenna, the power gain of 13 dBi was obtain at 700GHz by fabricating the two-dimensional 8 × 3 slot antenna arrays fed by CPW. The gain increased up to 31.5 dBi by coupling the double slot antenna with the extended hemispherical lens.
