LOW-PROFILE ANTENNA WITH HIGH ISOLATION FOR BLUETOOTH AND WIFI COEXISTENCE
A low-profile, planar antenna structure includes a planar dielectric substrate, a ground plane disposed on an underside of the planar dielectric substrate; a circular planar radiating element disposed on an upper side of the planar dielectric substrate; and four arc-shaped parasitic elements evenly spaced apart and surrounding the circular planar radiating element, the four-arc shaped parasitic elements and the circular planar radiating element configured to operate together as a first planar antenna, a second planar antenna, and a patch antenna. The planar antenna structure may include four notches formed in the circular planar radiating element and extending, from four respective evenly-spaced points on a circumference of the circular planar radiating element, radially inward toward a center of the circular planar radiating element.
CONTROLLING POWER CONSUMPTION IN A POWER AMPLIFIER IN A COMMUNICATION DEVICE
A method and apparatus are disclosed for controlling the power consumption of a power amplifier included in a communication device. For at least some embodiments, the power consumption may be controlled by determining an order for the data packets to be transmitted, selecting a coding scheme used to encode the data packets, and/or determining an output power level of the power amplifier. The data packet transmission order, the coding scheme, and/or the output power level may be determined, at least in part, by the temperature of the power amplifier, a quality of service associated with the data packets, a data packet length, and/or a link budget. Adjustments to the data packet transmission order, the coding scheme, and/or the output power level may be made dynamically for each data packet.
MULTIPLEXING AN RF SIGNAL WITH A CONTROL SIGNAL AND/OR A FEEDBACK SIGNAL
A communication device includes: a transmission line; a first circuit communicatively coupled to the transmission line and configured to receive an outbound signal over the transmission line, the first circuit comprising an amplifier configured to amplify the outbound signal to form an amplified signal, the first circuit being configured to transmit a first portion of the amplified signal to an antenna element; and a second circuit communicatively coupled to the transmission line and configured to produce the outbound signal and to transmit the outbound signal over the transmission line, the second circuit further being at least one of configured to transmit a control signal for the amplifier over the transmission line or configured to receive a feedback signal, based on the amplified signal, over the transmission line such that the outbound signal and at least one of the control signal or the feedback signal concurrently share the transmission line.
