Abstract
A wireless device having a mountable antenna element and an antenna array that operate simultaneously and efficiently on a circuit board within a wireless device. The mountable antenna element may be coupled to a ground layer of the circuit board. The antenna array may include dipole antennas incorporated within the circuit board and positioned within a close proximity to the ground layer. One or more stubs may be implemented on the circuit board near the dipole antenna array. Each antenna stub may create an impedance in the dipole elements which enable the antenna elements to operate efficiently while positioned in close proximity to the circuit board ground layer.
Claims23
A wireless device for transmitting a radiation signal, comprising:
- a circuit board that receives a mountable antenna element for radiating at a first frequency;
- an antenna array coupled to the circuit board;
- and
- a radio modulator/demodulator that provides a radio frequency (RF) signal to the mountable antenna and the antenna array.
(canceled)
A circuit board for transmitting a radiation signal, comprising:
- a coupling element for coupling to a mountable antenna element;
- an antenna array;
- a stub positioned in proximity to the antenna array, the stub generating an impedance in the antenna array;
- and
- a radio modulator/demodulator that provides a radio frequency (RF) signal to the mountable antenna and the antenna array.
A wireless device for transmitting a radiation signal, comprising:
- communication circuitry located within a circuit board, the communication circuitry generating a radio frequency (RF) signal;
- a plurality of antenna elements, wherein one or more of the plurality of antenna elements are arranged proximate the edges of the circuit board, each of the one or more of the plurality of antenna elements forming a radiation pattern when coupled to the communication circuitry and receiving a generated impedance within the antenna element;
- and
- a switching network that selectively couples one or more of the plurality of antenna elements and a mountable antenna coupling element to the communication circuitry.
