Abstract
Apparatus, systems and techniques for using composite left and right handed (CRLH) metamaterial (MTM) structure antenna elements and arrays to provide radiation pattern shaping and beam switching.
Claims22
A communication system, comprising:
- a ground electrode;
- and
- an antenna structure, comprising
- an input portion;
- a radiating portion;
- a capacitance element formed between the input portion and the radiating portion;
- and
- a shunt inductive element coupled between the radiating portion and the ground electrode, the shunt inductive element forming a shunt inductance from the radiating portion to the ground electrode, wherein the capacitance element forms a series capacitance between the input portion and the radiating portion, and wherein the communication system forms a Composite Right/Left-Handed (CRLH) structure having the series capacitance and the shunt inductance.
