Detuning feed seam antenna RTO terahertz wave source and manufacturing process

Abstract

The invention discloses a detuning feed seam antenna RTO terahertz wave source and a manufacturing process. The detuning feed seam antenna RTO terahertz wave source comprises a left electrode and a right electrode arranged on a main substrate, wherein the left side edge of the right electrode is embedded in a concave edge formed on the lower part of the right side of the left electrode, and a silicon dioxide layer is symmetrically arranged between upper and lower opposite end faces of two ends of each of the left electrode and the right electrode to ensure that air cavities communicating with one another are formed among the main substrate, the silicon dioxide layer, the left electrode and the right electrode, a convex block protruding towards the right electrode is formed in the middle part of the right side edge of the left electrode, and grooves are symmetrically formed in the left electrode positioned on two sides of the convex block, wherein the main substrate for forming bottom surfaces of the air cavities is positioned below the two grooves, a resonant tunneling diode is arranged between the bottom surface of the convex block and the upper end surface of the corresponding main substrate and has a knife structure, and the knife handle part of the knife structure is transversely inserted into a concave edge formed on the lower part of the left side of the right electrode. The detuning feed seam antenna RTO terahertz wave source disclosed by the invention can achieve oscillation of an oscillator at different frequency bands by changing the position of an RTD in the oscillator.

Description

Technical field [0001] The invention relates to a terahertz wave source. In particular, it relates to a RTO terahertz wave source and manufacturing process for an offset-fed slot antenna. Background technique [0002] Terahertz (THz) waves refer to electromagnetic waves with frequencies in the range of 0.1 terahertz to 10 terahertz, with wavelengths ranging from 0.03mm to 3mm, between millimeter waves and infrared. However, due to the high loss of THz waves in the air, a high-power wave source is needed to commercialize it in the communication field. The power of the existing terahertz wave source is too low, only a few to dozens of nanowatts, which restricts the development of terahertz technology. Therefore, this frequency band is a white space to be developed, also known as the terahertz gap. [0003] Since 0.1-10 terahertz waves can penetrate materials such as plastic, paper, wood, human body, atmosphere, etc., it can be widely used in security scanning, radio astronomy, biol...

AI Technical Summary

Problems solved by technology

The power of the existing terahertz wave source is too low, only a few to tens of nanowatts, which restricts the development of terahertz technology, so this frequency band is a blank frequency band to be developed, also known as the terahertz gap
