A communication device, computer program product, and method provide a heat sink antenna that performs dual functions of thermal energy transferring and radio frequency (RF) communication. The communication device includes a millimeter wave (mmWave) antenna module. The communication device includes a heat sink antenna having a first portion in thermal conductive contact with at least a portion of a surface of the mmWave antenna module. The heat sink antenna has a second portion extending away from the first mmWave antenna module to transfer thermal energy away from the first mmWave antenna module. An RF front end of the communication device includes mmWave transmitter that radiates a mmWave signal via the mmWave antenna module, resulting in generation of the thermal energy.

Multiple feed, front-shielded, coplanar waveguide, direct-fed, cavity-backed slot antennas are described. Various implementations form an antenna unit capable of millimeter waveform and/or microwave waveform transmissions. An antenna comprises a conductive plate that includes an aperture. The aperture has a shape that extends along an axis that bisects the aperture into first and second bisected portions, the first bisected portion having a first geometry type, and the second portion having a second geometry type that is a bilateral symmetry shape type of the first geometry type. In implementations, the aperture is configured to radiate waveforms within a frequency range from about between 600 Megahertz (MHz) to 72 Gigahertz (GHz) by applying multiple signal feeds to the conductive plate.

Various implementations form an antenna unit capable of millimeter waveform and/or microwave waveform transmissions. A bottom shielding structure of the antenna unit defines a cavity, where various implementations include one or more dampening structures within the cavity. Some implementations includes a slot antenna within the cavity defined by the bottom shielding structure, such as a coplanar waveguide (CPW) direct-fed slot antenna, to form a cavity-backed slot antenna. Some implementations connect a top shielding structure to the bottom shielding structure to encase the slot antenna. In one or more implementations, the top shielding structure includes aperture windows to allow waveforms within a frequency range from about between 600 Megahertz (MHz) to 72 Gigahertz (GHz). and radiated by the slot antenna to radiate outward from the antenna unit.

A method, wireless communication device (WCD), and computer program product deploys an additional, retractable antenna to enhance signal communication within an identified network. A processor executes an antenna deployment module (ADM) in order to determine a link status based on a quality and/or a strength of communication signals propagated via at least one stationary antenna. In response to the link status indicating that coverage of a second/target network is available or that a quality of a signal propagated within a first network is less than a threshold level, the ADM provides a deployment signal to a deployment component. In response to receiving the deployment signal, the deployment component deploys the retractable antenna by extending the retractable antenna from a stowed position to a deployed position. The ADM enables the WCD to communicate within the selected network via the deployed retractable antenna using a higher quality communication signal.

A communication device includes a processor subsystem that is in communication with a communication module, which is communicatively coupled to an antenna array to transmit and receive signals. The processor subsystem executes a near-field detection application to perform a method including transmitting, via the antenna array, a signal that is swept across a range of frequencies and receiving any back-scattered signals in the range of frequencies. The method includes determining whether a near-field obstruction exists based on characteristics of the received back-scattered signals. In response to determining that a near-field obstruction exists, the method includes triggering the processor subsystem to perform one or more responsive operations on the communication device. The operations include a selected one of: (i) altering a transmission beam transmitted by the communication device; and (ii) triggering an application to execute on the communication device, the application intended to interact with a user of the communication device.

The method further includes determining object position relative to the plurality of antenna arrays based on the set of mutual coupling values.

Systems and methods for providing resonant wireless charging in a portable communications device utilize antenna arms formed from openings in a metal unibody construction. Two of the antenna arms are driven by WiFi, GPS, and cellular drives respectively, while a wireless charging antenna sharing the same mechanical connections provides a differential drive across the antenna ends, forming a primary wireless charging coil. In an embodiment, a smaller multi-turn coil is connected to the primary wireless charging coil, and may overlay a device speaker and may also be shielded by a ferrite material. This structure or a dedicated similar structure on the device is then used for resonance-based wireless charging of the device.
