Abstract
A wireless communication system includes a transmission apparatus and a reception apparatus. The transmission apparatus includes two or more sending transmission lines located with feeding points of a signal or termination points opposed to each other, and a transmission unit configured to input the signal to the feeding points of the two or more sending transmission lines. The reception apparatus includes a receiving transmission line configured to establish electromagnetic field coupling with the sending transmission lines, and a comparator configured to input signals from one end and the other end of the receiving transmission line.
Claims16
A wireless communication system comprising:
- a transmission apparatus including at least two sending transmission lines located with at least either feeding points of a signal or termination points opposed to each other, and a transmission unit configured to input a signal to each of the feeding points of the at least two sending transmission lines;
- and
- a reception apparatus including a receiving transmission line configured to move along the at least two sending transmission lines, establish electromagnetic field coupling with the sending transmission lines, and receive an excited signal, and an output unit configured to receive respective signals from one end and another end of the receiving transmission line corresponding to signals propagating from different directions along the receiving transmission line, and output a signal to be subjected to demodulation processing based on a relationship between the respective signals received from the one end and the another end.
A reception apparatus configured to receive a signal from at least two sending transmission lines located with at least either feeding points of a signal or termination points opposed to each other, the reception apparatus comprising:
- a receiving transmission line configured to move along the at least two sending transmission lines, establish electromagnetic field coupling with the sending transmission lines, and receive an excited signal;
- and
- an output unit configured to receive respective signals from one end and another end of the receiving transmission line corresponding to signals propagating from different directions along the receiving transmission line, and output a signal to be subjected to demodulation processing based on a relationship between the respective signals received from the one end and the another end.
A control method for controlling a wireless communication system including a transmission apparatus and a reception apparatus, the transmission apparatus including at least two sending transmission lines located with at least either feeding points of a signal or termination points opposed to each other, and a transmission unit configured to input a signal to the at least two sending transmission lines, the reception apparatus including a receiving transmission line configured to move along the at least two sending transmission lines, establish electromagnetic field coupling with the sending transmission lines, and receive an excited signal, and an output unit configured to receive a signal from the receiving transmission line and output a signal to be subjected to demodulation processing based on the received signal, the control method comprising:
- causing the transmission unit to input the signal to each of the feeding points of the at least two sending transmission lines;
- and
- causing the output unit to receive respective signals from one end and another end of the receiving transmission line corresponding to signals propagating from different directions along the receiving transmission line, and to output the signal to be subjected to the demodulation processing based on a relationship between the respective signals received from the one end and the another end.
A control method for controlling a reception apparatus including a receiving transmission line and an output unit, the receiving transmission line being configured to move along at least two sending transmission lines located with at least either feeding points of a signal or termination points opposed to each other, establish electromagnetic field coupling with the sending transmission lines, and receive an excited signal, the output unit being configured to receive a signal from the receiving transmission line and output a signal to be subjected to demodulation processing based on the received signal, the control method comprising:
- causing the output unit to receive respective signals from one end and another end of the receiving transmission line corresponding to signals propagating from different directions along the receiving transmission line, and to output the signal to be subjected to the demodulation processing based on a relationship between the respective signals received from the one end and the another end.
