Abstract :
A V-shaped slot antenna built on a dielectric substrate is presented. The antenna is a nonresonant, traveling-wave design, with a predicted impedance in the range from 50 Omega to 80 Omega . Calculations indicate that this antenna should have a gain of 15 dB with 3 dB beamwidths of 10 degrees in the H plane and 64 degrees in the E plane. Pattern measurements at 90 GHz support the theory. It should be possible to equalize the 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 at wavelengths as short as 10 mu m with conventional photolithography.<>
