Abstract
Techniques, apparatus and systems that use one or more composite left and right handed (CRLH) metamaterial structures in processing and handling electromagnetic wave signals. Antennas and antenna arrays based on enhanced CRLH metamaterial structures are configured to provide broadband resonances for various multi-band wireless communications.

26. An antenna device, comprising:
-
a substrate having a first surface on a first side and a second surface on a second side opposite to the first side; a ground electrode formed on the first surface leaving part of the first surface exposed to have an exposed surface part; a composite left and right handed (CRLH) metamaterial structure comprising; (i) one or more unit cells including at least a portion of the exposed surface part, and (ii) one or more conductive strips formed on the first surface and coupling the one or more unit cells to the ground electrode; and a feed line formed on the second surface having a distal end capacitively coupled to the CRLH metamaterial structure and directing an antenna signal to or from the CRLH metamaterial structure; wherein the CRLH metamaterial structure and the feed line are configured to exhibit one or more left handed (LH) resonant modes and one or more right handed (RH) resonant modes associated with the antenna signal. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

50. An antenna device, comprising:
-
a first substrate having a first surface on a first side and a second surface on a second side opposite to the first side; a second substrate having a third surface on a first side and a fourth surface on a second side opposite to the first side, the first and second substrates stacking over each other to engage the second surface to the third surface; a middle metallization layer formed between the second and third surfaces and patterned to form one or more conductive patches; a ground electrode formed on the first surface leaving part of the first surface exposed to have an exposed surface part; a composite left and right handed (CRLH) metamaterial structure comprising; (a) one or more unit cells including at least a portion of the exposed surface part, and (b) one or more conductive strips formed on the first surface and coupling the one or more unit cells to the ground electrode; and a feed line formed on the fourth surface having a distal end capacitively coupled to the CRLH metamaterial structure and directing an antenna signal to or from the CRLH metamaterial structure; wherein the CRLH metamaterial structure and the feed line are configured to generate one or more left handed (LH) resonant modes and one or more right handed (RH) resonant modes associated with the antenna signal. - View Dependent Claims (51, 52, 53, 54)
