[仿真]Antennas and Waveguides for Far-Infrared Integrated Circuits

Abstract-Antennas and waveguides for the wavelength range 0.1-3 @]F1J  
mm are considered. Emphasis is placed on those designs which lend 'nRoa7v(  
themselves to integration with each other and with other components }p|S3/G?$!  
such as diodes. The general properties of FIR antennas are reviewed. A J1UG},-h  
novel silicon waveguide antenna is discussed, and its design, simulation, v1O1-aM  
fabrication, and performance at 119 pm are described. This antenna ` G-V %  
has a highly symmetrical, single-lobed beam with 3 dB beamwidths of 6 @A'N(I=O  
35 and 38” in the E- and H-planes, respectively. The gain (measured in B9(@.  
microwave simulation) is 12.8 dB. This antenna is well suited for integration :tf'Gw6v  
with Schottky diodes. 7U647G(Sg  
The related subject of FIR waveguides is discussed. Experiments Nbvs_>N  
with metal transmission lines at 119 pm are described and dielectric "zZZ h  
guides related to the waveguide antenna are also considered. Using uEui{_2$  
components such as these it may s .. H~:EPFi.(
