US Patent 8,350,763: Active Antennas for Multiple Bands in Wireless Portable Devices

• Title: Active antennas for multiple bands in wireless portable devices
• Assignee: Massively Broadband LLC
• Inventor: Theodore S. Rappaport
• Filing Date: August 14, 2009
• Issue Date: January 8, 2013
• Abstract: The patent describes wireless devices, particularly mobile devices such as cellphones, PDAs, computers, and navigation devices, which transmit or receive signals across multiple frequency bands. These devices can simultaneously transmit or receive on different bands, or transmit and receive simultaneously on different bands. The core innovation allows a single physical antenna structure to be used for both transmission and reception across many different bands. This antenna can be either actively tuned or passively tuned using electronically controlled elements.

Plain-Language Overview of Independent Claims:

• Claim 1: A wireless device is described that includes one or more antennas and multiple transmitting, receiving, or transceiving components operating in various frequency bands. At least one of these antennas is shared by these components across different bands. This shared antenna is either actively tuned or uses electronically controlled passive elements for tuning.
• Claim 6: This claim also describes a wireless device with one or more antennas. It specifies at least one component (transmitter, receiver, or transceiver) that works across multiple bands, a tuner connected to this component, and a controller that manages the tuner's adjustments for different bands. Similar to Claim 1, at least one antenna is shared by the multiband component, and its tuning is achieved either actively or through electronically selected/interconnected passive elements.
• Claim 10: This claim outlines a wireless device featuring at least one antenna and at least one transmitting, receiving, or transceiving component, both designed for multiple frequency bands. Crucially, a tuner connects the multiband antenna to the multiband component, and this tuner is capable of matching their impedances across various frequency bands simultaneously.
• Claim 13: A wireless portable device is described, having one or more antennas that send or receive electromagnetic energy across specific frequency bands, with at least one antenna handling multiple bands. It also includes one or more components (receivers, transmitters, or transceivers) connected to this antenna. The distinguishing feature is that either a single component operates simultaneously on two or more of these frequency bands, or multiple components collectively operate simultaneously on two or more of these bands.
• Claim 17: This claim covers a component for a wireless device, which can be a tuner, a set of tuners, a controller, or other circuitry. This component is designed to be connected to at least one antenna and multiple transmitting, receiving, or transceiving units that operate on various frequency bands. The arrangement dictates that the single antenna is utilized by these multiple units across different bands, and its tuning is either active or performed by electronically controlled passive elements.
