摘要

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 feeding mechanism for a HWLW antenna is considerably simplified compared to the FWLW antenna. This paper discusses arraying these antennas to provide both increased gain and scanning capability. It will be seen that arraying HWLW antennas is more complex than its narrowband counterpart, the patch antenna.
