Abstract
A nonresonant, traveling-wave V-shaped slot antenna providing high gain and a broad bandwidth for coupling infrared radiation onto a detector. The V-shaped slot antenna includes a relatively thick dielectric substrate and a metallization layer formed on the substrate. The metallization layer includes a pair of slots positioned at an angle .phi..sub.1 to form a V-shaped slot. The slot angle .phi..sub.1 is equal to approximately twice the radiation angle .psi., which is defined as the arccos of v.sub.d /v.sub.s, where v.sub.s is the propagation velocity of the infrared radiation in the two slots and v.sub.d is the propagation velocity of the radiation in the dielectric substrate. At the slot angle .phi..sub.1, the radiation in the two slots adds in phase to produce a single high-gain beam along the V axis.
