A radiator for terahertz electromagnetic radiation includes one or more radiator units. Each of the one or more radiator units respectively includes: an oscillator arrangement operable to generate third harmonic power, and a patch antenna arrangement operably coupled with the oscillator arrangement for radiating terahertz electromagnetic radiation based on the generated third harmonic power.

Radiator for terahertz electromagnetic radiation

A radiator for terahertz electromagnetic radiation. The radiator includes one or more radiator units. Each radiator unit includes an oscillator operable to generate second harmonic power, and a patch antenna operably coupled with the oscillator for radiating terahertz electromagnetic radiation based on the generated second harmonic power.

A device for signal generation including a unit cell. The unit cell contains two oscillators that are coupled in phase. Each oscillator operates at a fundamental frequency. Each oscillator further includes a slot structure, and the slot structures serve as, at a third harmonic of the fundamental frequency, a slot antenna radiating a third harmonic power. If the device contains multiple unit cell, then each unit cell is horizontally coupled out-of-phase and vertically in-phase with adjacent cells at the fundamental frequency in the device. Therefore, coherent radiation and power combining are achieved at the third harmonic.
