ANTENNA ARRANGEMENT OF A WIRELESS NODE |
| 摘要 |
A wireless node (10) comprises an RF modem (12), an RF switch array (14) connected to the RF modem, the RF switch array comprising a layer of circuit board sandwiched between layers of conductive material, and a plurality of antennas (16) arranged in a horizontal plane and connected to the circuit board of the RF switch array via waveguides present in the layers of conductive material. A method of operating the wireless node comprises generating radio signals at the RF modem (12), communicating the generated radio signals to the RF switch array (14), selecting an antenna (16) for transmitting the generated radio signals and transmitting the generated radio signals from the selected antenna. |
