Titel:
Surface-Wave Coupling of Active Antennas for Homodyne Sensor Systems 
Abstract:
In this paper, we present a novel method for significantly enhancing the performance of low cost millimeter wave sensors systems based on active integrated antennas. Our method uses the planar active antenna's parasitic surface-wave field as a LO signal for a mixing rectenna. Compared to a self-mixing active 67 GHz antenna, the surface-wave coupled rectenna receiver shows a considerably improved MDS (10 dB lower) and the possibility for high quality homodyne I/Q signal detection
