Problems solved by technology

However, due to the high loss of THz waves in the air, high-gain transmission sources and sufficiently sensitive detection antennas are required, which prevents them from being commercialized in the communication field and restricts the development of technology. Therefore, this frequency band is a blank frequency band to be developed. , also known as the THz gap

Abstract

The invention discloses a detuning feed seam array antenna based on a resonant tunneling mechanism, and belongs to the field of antennas. The detuning feed seam array antenna comprises detuning feed seam array antenna bodies and two resonant tunneling diodes (RTD), wherein the RTDs serve as excitation components and are used for generating Terahertz (THz) waves, and the detuning feed seam array antenna body serves as an electromagnetic wave emitting component and is used for emitting the THz waves generated by the RTDs. The upper electrode of the RTD1 and the upper electrode of the RTD2 are connected with the corresponding left electrodes of the detuning feed seam array antenna bodies respectively through heat sink; the lower electrode of the RTD1 and the lower electrode of the RTD2 are respectively connected with the corresponding right electrodes of the detuning feed seam array antenna bodies. By means of the detuning feed seam array antenna, output power of a THz oscillator formed by combining the RTDs and the detuning feed seam array antenna bodies can be substantially improved, and the detuning feed seam array antenna has great significance in super-high-speed data link transmission, wireless communication, military, national defense and other fields.

Description

technical field [0001] The present invention relates to antenna technology and terahertz (THz) technology, in particular to offset feeding slot array antenna technology. Background technique [0002] THz waves refer to electromagnetic waves with a frequency in the range of 0.1THz to 10THz, and a wavelength in the range of about 0.03mm to 3mm, which is between millimeter waves and infrared. However, due to the high loss of THz waves in the air, high-gain transmission sources and sufficiently sensitive detection antennas are required, making it impossible to commercialize in the field of communication, which restricts the development of technology, so this frequency band is a blank frequency band to be developed , also known as the THz gap. [0003] Due to the special electromagnetic spectrum position of THz, it has many superior characteristics and has very important academic and application value, such as the application of THz imaging and THz spectroscopy in physics, chemi...
