1. A communication system, comprising:
- a ground electrode; and
an antenna structure, comprisingan 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.
