Leaky-wave antennas are interesting apertures for a variety of applications due to their low profile and wide bandwidth. They are inherently traveling wave antennas, and hence are best suited for end-fire applications. A new type of leaky-wave antenna, the half-width leaky-wave antenna (HWLW), has been recently investigated and found to have similar radiation properties as its full-width leaky-wave (FWLW) counterpart, but only requiring half the transverse dimension. In addition, the ...
Leaky-wave antennas offer the potential for a wide operational bandwidth from a very thin antenna. Recently, a leaky-wave antenna that is half the usual width of a planar microstrip leaky-wave antenna was proposed. One of the major advantages of this design is that it requires only a single, rather simple, feed mechanism. To maintain the full potential bandwidth of that antenna, an appropriate termination is required. In this paper, a ...
Magneto-dielectric materials offer a new design space for radio frequency (RF) passive components such as antennas, circulators, feed networks, radomes, etc. Polymer nanocomposites offer a means to tailor electric and magnetic properties as well as define necessary mechanical and thermal properties. Recent advances in nanocomposite synthesis methods offer the potential for dramatically different electric and magnetic properties as compared to conventional materials. This research project investigated homogenization techniques, measurement techniques, ...
