Abstract:
We are developing integrated and receivers antennas for terahertz applications. As the remote-sensing/radio-astronomical frequencies are pushed higher into the millimeter and submillimeter- wave regions, integrated antennas and receivers become competitive with standard waveguide receivers. The integrated receivers consist of an antenna integrated directly with a matching network/mixer. Integrated antennas and receivers are easier to manufacture, more reliable and much less expensive than waveguide receivers. The integration also allows the use of linear or two-dimensional arrays without a dramatic increase in cost. The heart of an integrated receiver is the planar antenna and the antenna/mixer matching network. We have concentrated our efforts into the development and optimization of the high-efficiency integrated horn antenna (Fig. 1). The antenna consists of a dipole suspended in a pyramidal cavity etched in Silicon.The horn antennas are typically between 1[lambda] and 1.5[lambda]-square, and show excellent patterns at 93 GHz with a directivity around 10-12 dB. In the past year, we have achieved significant advance in the analysis and optimization of integrated horn antennas and the projects are summarized below.
