Abstract:
The embodiments contemplate a printed circuit board of at least two layers for providing remote wireless communication between a wireless device and a unit, as well as methods of creating an omni-directional radiation pattern for transmitting/receiving information using a notch antenna formed in the printed circuit board having radio frequency circuitry. The notch antenna, with a closed and opened end, may be etched or embedded into a ground plane conductor on a first layer of the board. A transmission line positioned on the bottom surface of a second layer of the board crosses under the portion of the board containing the notch antenna. A first and second intermediate layer electrically connected between the first layer and the second layer may serve as return ground planes for the transmission line. A capacitive circuit, positioned in series with the transmission line and across the notch antenna, functions to reduce and/or eliminate inductance of the transmission line.
