Abstract
A dual-band antenna or coupled resonators, related wireless device applications, and methods of manufacturing the same are provided. Embodiments of the antenna have resonant frequencies in a lower 2-3 GHz frequency band and a higher 5-6 GHz frequency band range. The antenna has a high frequency portion that may be configured to operate as an inverted F antenna. The high frequency element is also positioned adjacent to a nearby parasitic element. In operation, the high frequency element and the parasitic element couple together and form a current loop, or loop antenna which is configured to resonate at a low frequency band.
