摘要： The modulating and demodulating device comprises a microstrip line network (1) connected to a transmitting/receiving antenna (7), the modulator-demodulator having first and second diodes (11,12) connected to an output of the microstrip line network, and a bias voltage supplying circuit (4) for supplying a bias voltage selectively to the first and second diodes. In the modulator-demodulator, the first diode is connected between the input and output terminals, and the second diode is connected between the input terminal and a reference potential point. When the modulator-demodulator executes a modulating operation, the bias voltage supplying circuit supplies a bias voltage to turn on both the first and second diodes or a bias voltage to turn on only the first diode in accordance with a modulation signal. When the modulator-demodulator executes a demodulating operation, the bias voltage supplying circuit supplies a bias voltage to turn off both the first and second diodes.

摘要： There is provided an ASK modulator which can obtain the Errorless ASK modulated signal even if the ringing phenomenon is generated when the digital signal changes to the logical low level from the logical high level.
The ASK modulator comprises a switching diode (1) connected in series to a carrier signal transmitting path, a first resistor (4) connected between one end of the switching diode and a digital signal input end (9) and a second resistor (10) connected between one end of the switching diode and the reference voltage point. The digital signal to be applied to the digital signal input end is divided by first and second resistors and the switching diode is turned ON and OFF to generate the ASK modulated signal with the logical level of the divided digital signal. In this case, the switching level of the switching diode rises substantially to prevent that the switching diode turns ON by the ringing phenomenon.

摘要： An antenna structure includes a radiation conductor made of a metal plate that is supported by legs provided upright on a surface of a dielectric substrate and is spaced apart from the surface. The radiation conductor is circularly shaped such that the contour of the radiation conductor conforms to the outer periphery of the dielectric substrate and such that the radiation conductor includes an open portion. One of the legs functions as a feeding terminal and the other functions as a grounding terminal, whereby the radiation conductor operates as a dipole antenna. The radiation conductor has slots for adjusting impedance. Impedance can be adjusted by changing the length of the slots.
