Lumped Element and Leaky-Wave Antennas for Millimeter Waves.
Abstract
This abstract is concerned with certain types of antennas for millimeter waves that cannot be successfully scaled from their microwave frequency counterparts Among these antennas, we chose first to explore novel antennas of the leaky-wave type, largely because they form a natural class of antennas for millimeter waves. Leaky-wave antennas for the millimeter wave range face two main problems. The first relates to the small wavelengths involved, which require small waveguide dimensions and pose fabrication difficulties. The second problem is higher metal loss. We are overcoming the first of these problems by considering leaky-wave structures with longitudinally-continuous apertures, and the second by basing the antennas on low-loss waveguides. With these essential features in mind, our program involves two parallel approaches to the same basic problem: novel leaky-wave antennas suitable for millimeter wavelengths. The parallel approaches employ, first of all, two different basic low-loss waveguides, and second, two different mechanisms to produce leakage. As a result, two new antenna types have emerged.
