“…This resonance frequency usually lies in the UV, while some metals like Au have their resonance in the visible. Clearly, scale modeling will fail when approaching these frequencies, though in the infrared, Rutledge et al [39] report similar patterns for cat whisker antennas using an RF scale model and an actual device. A second limitation is that the surface impedance is higher for higher frequencies because of the skin effect [36], [39].…”

The reactance of the surface impedance dominates the resistive part at higher frequencies, which complicates antenna behavior.…”

Abstract-A promising approach to localized spectroscopy at far-infrared ( 5 m) and terahertz frequencies (100-3000 GHz) is with scanning probe microscopes by transducing far-field radiation to the near field with a field confinement structure-a near-field antenna. Here we discuss the background of this idea and show encouraging results from a scale-model experiment using 3-GHz microwave radiation. We also present experiments to scale antennas to visible wavelengths and we discuss limits to scale modeling.Index Terms-Atomic force microscopy, coaxial aperture antennas, infrared spectroscopy, millimeter-wave antennas.

Abstract-A new V-shaped slot antenna built on a dielectric substrate is presented. The antenna is a non-resonant, travelling-wave design, with a predicted impedance in the range from 50R t o €400. Calculations indicate that this antenna should have a gain of 15 dB with 3-dB beamwidths of loo in the H plane and 134'in the E plane. Pattern measurements at QOGHz support the theory. It should be possible t o equalize t h e two beamwidths with a cylindrical lens. The broad bandwidth and high gain characteristics make the slot-V a good candidate for picosecond optoelectronic measurements. Fabrication is simple, and it should be possible to make this antenna a t wavelengths as short as 10pm with conventional photolithography.

Abstract. Some properties of printed antennas and arrays for uncooled silicon plasmon detector arrays based on field effect transistors are shortly discussed. Antenna geometry has been optimised for maximising gain at 300 GHz. It is shown that for bow-tie antennas in the arrays in diffraction limit approximation, there are almost no cross-talks between the neighbour antennas. It is shown that the gain for one antenna is higher than that for antenna, in the array.
