Title: Composite antenna
Inventor: KOUNO MITSUNORI
IPC: H01Q5/00
Filed: 1978-06-29
Abstract: PURPOSE:To obtain a composite antenna which is capable of transmission and reception of more than two signals of different frequencies as well as the facilitated miniaturization. CONSTITUTION:High frequency signals fH fed from feeder terminals 5a and 5b are supplied to high frequency coupling coil 12 with no loss virtually via capacitors 14a and 14b. Thus the high frequency electromagnetic field is generated at radiation element 11, and the electromagnetic waves are radiated into the space. In this case, high frequency signals fH are generated across low frequency coupling coil 13 by the high frequency electromagnetic field. But no high frequency current flows to coil 13 since the passage of the high frequency signals is blocked by choke coils 15a and 15b, and accordingly no evil effect is given to the radiation action of signal fH. On the other hand, low frequency signals fL supplied from feeder terminals 6a and 6b are fed to the low frequency coupling coil with no loss substantially via coils 15a and 15b. Thus the low frequency electromagnetic field is generated to element 11, and this inductive magnetic field is radiated into the space.

Abstract: PURPOSE:To attain simultaneous transmission of voice and picture and to reduce the cost of the device by sending a picture signal and a voice signal in band split, passing through the picture signal through a band limit low pass filter and applying phase amplitude modulation. CONSTITUTION:A modulation section of a modulation and demodulation circuit 40 pass 2 kinds of still picture signals sent from a CPU 11 to band limit low pass filters 25I, 25Q, a carrier signal with a prescribed frequency is used to apply phase amplitude modulation to obtain a picture signal phase amplitude modulation signal. Moreover, a signal of a specific frequency band corresponding to the picture signal phase amplitude modulation signal is eliminated from the voice signal to be inputted to form the transmission voice signal. Then the picture signal phase amplitude modulation signal and the transmission signal are synthesized and the still picture signal and the voice signal are subject to generating frequency band split to send them simultaneously. Thus, the simultaneous transmission of the voice and picture is attained and a highly accurate band pass filter is not required.
