Multi-band antenna structure
First Claim
1. An antenna comprising:
- a radiating component to transmit and receive signals, wherein the radiating component includes at least one integrated inductive element; and
a capacitive element that electromagnetically couples to the integrated inductive element to form a tuned circuit that allows the antenna to operate in more than one frequency range.

Abstract
The invention provides a multi-band antenna structure for use in a wireless communication system. The antenna structure includes integrated inductive elements and capacitive elements that function as a tuned circuit to allow the antenna structure to operate in multiple frequency ranges. In particular, the capacitive elements electromagnetically couple to the inductive elements. The capacitive elements provide the inductive elements with parallel capacitance at a given set of frequencies, thereby providing the antenna structure with frequency selectivity. At a particular frequency range, the inductive elements act as short circuits, thereby lengthening the radiating elements, which radiate energy at the particular frequency. At another frequency range, the inductive components act as open circuits, virtually shortening the radiating elements in order to radiate the higher frequencies. In this manner, the multi-band antenna structure operates within multiple frequency ranges.
