摘要： The present invention relates to a device for detecting millimeter waves, having at least one field effect transistor with a source, a drain, a gate, a gate-source contact, a source-drain channel, and a gate-drain contact. Compared to a similar such device, the problem addressed by the present invention, among others, is that of providing a device which enables the provision of a field effect transistor for detecting the power and/or phase of electromagnetic radiation in the Thz frequency range. In order to create such a device, it is suggested according to the invention, that a device be provided which has an antenna structure wherein the field effect transistor is connected to the antenna structure in such a manner that an electromagnetic signal received by the antenna structure in the THz range is fed into the field effect transistor via the gate-source contact, and wherein the field effect transistor and the antenna structure are arranged together on a single substrate.
