Systems and methods for a wireless modem assembly
First Claim
1. 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.

Abstract
A RF wireless modem with an integral antenna. The antenna is a compact, horizontally-polarized, balanced, multi-element, directional antenna with integral balun, constructed on one end of a printed wire board (PWB) and radiating preferably away from the modem circuitry on the remaining portions of PWB. The antenna includes a matching network for matching an impedance of the antenna with an impedance of an unbalanced connection and a balun for transforming a RF transmit signal received from the unbalanced connection into a balanced RF transmit signal. The antenna also includes a radiator for transmitting the balanced RF transmit signal and a reflector for reflecting at least some of the energy of the transmitted signal away from the modem circuitry. The antenna can also include a director for directing the RF transmit signal in a desired direction.
