Integrated Tapered Slot Antenna Arrays and Devices

Authors:
K. Sigfrid Ynguesson
Abstract:
The potential advantages of integrating antenna elements/arrays with active devices has made this into an area which has received increasing emphasis among millimeter wave/submillimeter wave researchers. This paper reviews the status of one type of antenna element which shows great promise for such applications - the Tapered Slot Antenna (TSA). We will cover some recent advances in this area, with particular emphasis on the potential application of TSA arrays in THz Space Technology. Examples are given of applications with relevance to THz Space Technology in three areas: (1) Focal plane arrays for imaging; millimeter wave prototypes at 35 and 94 GHz have demonstrated system aperture efficiencies (i.e. total coupling efficiencies) of over 50%, with angular resolution close to the Rayleigh criterion. (2) Quasi-optical power-combining with high radiative efficiency, as demonstrated by a 32 GHz prototype developed together with JPL. (3) Integrated receivers, such as SIS mixers, and a new two-dimensional electron gas element.
