Non-planar metamaterial antenna structures

摘要

Antennas for wireless communications based on metamaterial (MTM) structures to arrange one or more antenna sections of an MTM antenna away from one or more other antenna sections of the same MTM antenna so that the antenna sections of the MTM antenna are spatially distributed in a non-planar configuration to provide a compact structure adapted to fit to an allocated space or volume of a wireless communication device, such as a portable wireless communication device.

主权项

1. An antenna assembly, comprising:
a first section comprising a first conductive portion mechanically coupled to a first dielectric portion, the first section defining a first surface; and a second section comprising a second conductive portion mechanically coupled to a second dielectric portion, the second section defining a second surface, the second surface including a non-parallel orientation with respect to the first surface; wherein the first and second conductive portions are configured to form a composite right and left handed (CRLH) metamaterial (MTM) structure supporting a left-handed resonant mode corresponding to a first specified range of frequencies and a right-handed resonant mode corresponding to a second specified range of frequencies.
