    摘要: A system for wireless communication between a plurality of semiconductor chips is disclosed. Each data line in the present invention is coupled with a transmitter for transmitting information to any other semiconductor chip. Furthermore, each data line is coupled with a receiver for receiving information transmitted by any transmitter. The system also comprises multiple antennas, fabricated from the chip's metalization layer. Nonetheless, separate antennas within the chip packaging can also be used. The antenna unit comprises a dipole and a loop antenna in a planar arrangement, thereby forming a spherical electromagnetic pattern of coverage and making the orientation between semiconductor chips for transmission purposes substantially irrelevant. Each transmitter in the system comprises a modulator for modulating the information being transmitted, while each receiver comprises a demodulator for demodulating the information transmitted. Several modulation schemes can be employed, though amplitude modulation is preferred, whereby each transmitter has a distinct carrier frequency within the operative radio frequency spectra--preferably above 900 MHz. Each transmitter and receiver is coupled to a power source comprising a capacitor, as a signal generator, and a rectifying circuit. To ensure that the communication between chips is noise/interference free, the entire system is shielded with a metal housing.
