Patent ID: 7023909

Claim:
A wireless modem assembly, comprising: a processor for encoding a baseband transmit signal and receiving a baseband receive signal; a transceiver for modulating the baseband transmit signal with an RF carrier signal to produce an RF transmit signal and for demodulating an RF receive signal with an RF carrier signal to produce the baseband receive signal; a horizontally polarized antenna for transmitting the RF transmit signal and for receiving the RF receive signal; and an unbalanced connection between the transceiver and the antenna, the connection configured to interface the RF transmit signal to the antenna and to interface the RF receive signal to the transceiver, and wherein the antenna comprises: a matching network for matching an impedance of the unbalanced connection with an impedance of the antenna; and a balun for transforming the RF transmit signal received from the unbalanced connection into a balanced RF transmit signal.
