Systems and methods are disclosed to transmit and receive radio frequency (RF) signals by providing a plurality of high gain, highly directional antennas on a multi-layer printed circuit board; using a processor to gate RF signals from each antenna and to select an antenna transmission pattern based on antenna turned on or the combination of a number of antennas turned on, among others.

Printed circuit board based smart antenna

A mobile phone hand-free extension device includes a FM radio transmitter with an active frequency searching circuitry to utilize a vehicular FM radio receiver for reproducing the audio signals from the mobile phone. The active frequency searching circuitry in this invention automatically detects which frequency band the vehicular FM radio receiver is currently using and set the RF frequency of the FM transmitter to the detected frequency. The FM transmitter relays the audio signals from the mobile phone by transmitting the audio signals through radio wave to the vehicular FM radio receiver to be reproduced by the speaker of the receiver.
