Abstract: Apparatuses, methods, and systems for an antenna assembly, are disclosed. One apparatus includes a multiple layer printed circuit board (PCB), a dielectric plate, and antenna elements. The PCB includes antenna excitation feed elements, wherein the antenna excitation feed elements are located on a layer of the PCB. A second surface of the dielectric plate is affixed to a first surface of PCB forming gaps adjacent each of the antenna excitation feed elements, wherein a dielectric constant of the dielectric plate, a thickness of the dielectric plate, and a thickness of the gaps are selected based on an operating frequency of wireless signals communicated through the antenna assembly, and based on RF (radio frequency) characteristics of the PCB. Each of the antenna elements are affixed to a first surface of the dielectric plate.

Abstract: An enhanced keyboard for controlling a device, including: a keypad with a plurality of depressible keys; a controller with a pre-designed integer number of output lines (J) and a pre-designed integer number of input lines (K); a printed circuit with switch mechanisms that are adapted to enable an electronic signal to pass from a specific output line of the controller to a specific input line of the controller responsive to depressing a specific key of the keypad; and one or more additional switch mechanisms that are adapted to enable an electronic signal to pass from a specific output line of the controller to at least two specific input lines of the controller responsive to depressing a specific key of the keypad.

Abstract: A transceiver card for a personal computer includes a single circuit board that plugs into the personal computer and that is coupled to exchange data via an industry-standard bus in the personal computer. Radio frequency modulation circuitry on the circuit board receives the data and transmits radio frequency signals responsive thereto. Receiver circuitry receives radio frequency signals and converts the received signals to data for transfer via the bus. In an alternative configuration, the transceiver includes two circuit boards coupled to a USB bus within an external box. Data is exchanged with the computer through a USB port in the computer.
