1. An antenna device comprising:
- a substrate;
a ground electrode formed on the substrate;
a feed line formed on the substrate;
a loading element coupling the feed line and the ground electrode; and
a shorting stub formed on the substrate and coupling the feed line and the loading element to the ground electrode,wherein the feed line directs an antenna signal to or from the loading element, andwherein the feed line and the loading element are structured to form a composite right and left handed (CRLH) metamaterial structure that supports a plurality of frequency resonances associated with the antenna signal.

9. An antenna device, comprising:
-
a first substrate having a first surface; a second substrate placed in parallel to the first substrate and having a second surface engaged with the first substrate and a third surface opposite to the second surface; a ground electrode formed on the second surface; a feed line formed vertical to the first surface and the second surface, having a first end on the first surface and a second end on the second surface; and a loading element having a first portion formed on the first surface and a second portion formed vertical to the first surface and the second surface, the first portion coupled to the first end of the feed line and the second portion coupled to the ground electrode on the second surface, wherein the feed line directs an antenna signal to or from the loading element, and wherein the feed line and the loading element are structured to form a composite right and left handed (CRLH) metamaterial structure that supports a plurality of frequency resonances associated with the antenna signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
