The first LWA cell can include a tunable component. The first LWA cell can also include a first conductive patch coupled to: a radio frequency (RF) feed on a first edge of the first conductive patch; a ground plane through a first via on a second edge of the first conductive patch; and a tunable component at a first corner between a third edge and a fourth edge of the first conductive patch. The second LWA cell can include a second conductive patch coupled to the ground plane through a second via on a second edge of the second conductive patch and coupled to the tunable component at a first corner between a first edge and a third edge of the second conductive patch.

Abstract: Embodiments of the subject technology provides a novel approach to address desense and provide electrostatic discharge (ESD) protection among components for a collocated antenna and speaker configuration in a mobile computing device. The available metal around the periphery of speaker components are used as part of implementing an antenna(s) and also for tuning the antenna, which results in an efficient antenna design that can be implemented within an available (relatively small) area of a PCB and also without adding components, which could further increase the overall cost of the mobile computing device. An inductor is used to isolate the antenna away from a ground to mitigate desense for the antenna. The inductor is connected to a diode and capacitor in series. The diode provides ESD protection for the speaker. The capacitor is connected to the diode in parallel to shunt nonlinearities generated by the diode to ground.

Abstract: A wideband antenna apparatus including a harmonically suppressed low band antenna is provided. The low band antenna is configured as a folded monopole antenna with patch coupling for resonance in a first frequency band. A patch portion of the low band antenna is widely separated from a folded feed portion of the low band antenna to avoid slot resonances above the first frequency band. The patch portion is relatively large to avoid folding of the patch portion that could introduce resonances above the first frequency band. The wideband antenna apparatus may also include a high band antenna proximate with the low band antenna. The high band antenna may be a folded monopole patch coupled antenna configured for resonating in a second frequency band. The high band antenna may optionally be configured like the low band antenna to suppress resonances of the high band antenna above the second frequency band.

Abstract: Technologies directed to a wireless network with a cascaded star topology with multiple devices at multiples nodes are described. In one wireless network, multiple devices are manufactured as a common device type and deployed at different nodes of the wireless network. The devices are configured to operate as a base station (BS) role, a gateway (GW) role, a relay (RL) role, or a customer station (STA) role. The nodes can be a base station node (BSN), a relay node (RLN), or a customer premises equipment (CPE) node. One node can be a first-tier hub of the cascaded star topology and another node can be a second-tier hub of the cascaded star topology.

The second WLAN radio communicates with a radio of a second wireless network device using the second antenna over a second LOS wireless link (e.g., 5 GHz) that is external to the building. The first antenna is located inside the building and the second antenna is located along an exterior surface of the building.
