Abstract
Multi-element antenna apparatus for mobile devices and methods of utilizing the same. In one embodiment, the antenna apparatus includes three antenna elements configured to operate in a plurality of frequency bands. The antenna elements are to a transceiver engine of a radio frequency communications device. Two of the three antenna components are configured to operate in transmit and receive modes. The third antenna component is configured to operate in receive mode. In some embodiments of an antenna apparatus operable in a carrier aggregation communication mode, two antenna components may be electrically combined into a single antenna component. The combined antenna component, characterized by a larger dimension and a larger operating bandwidth, may be operable simultaneously in two frequency bands, thereby enabling the carrier aggregation intra-band communication.
