Abstract
An antenna is provided for use in a wireless communications device having receive and transmit circuitry within a housing for receiving and transmitting radio signals. The antenna is built into the housing of the wireless communications device. A coupling plate is provided within the housing for transferring received and transmitted radio signals between the antenna and the receive and transmit circuitry. The coupling plate is connected to the receive and transmit circuitry and spaced from the antenna by a distance h1, such that the received and transmitted radio signals are transferred between the antenna and the receive and transmit circuitry only by capacitive coupling between the antenna and the coupling plate.
