Patent abstract
A high-power broadband radiation system and method are disclosed. The system includes an array of harmonic oscillators with mutual coupling through quadrature oscillators. Based on a self-feeding structure, the presently disclosed harmonic oscillators simultaneously achieve optimum conditions for fundamental oscillation and 2nd-harmonic generation. The signals at the second harmonic radiate through on-chip slot antennas, and are in-phase combined inside a hemispheric silicon lens attached at the backside of the chip. In some embodiments, the radiation of the system can also be modulated by narrow pulses generated on chip, thereby achieving broad radiation bandwidth.
