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 micro-strip slot antenna based on the resonant tunneling mechanism and belongs to the field of antennae. The antenna comprises a round patch antenna body provided with an H-shaped slot, and a resonant tunneling diode (RTD), wherein the RTD serves as an exciting device and is used for generating terahertz (THz) waves, the round patch antenna body provided with the H-shaped slot serves as a transmission device and used for transmitting the THz waves generated by the RTD out, the top electrode of the RTD is connected with the round patch antenna body, and the bottom electrode of the RTD is connected with the stratum. The micro-strip slot antenna based on the resonant tunneling mechanism has great significance in fields such as super-speed data link transmission, wireless communication and military national defense.

Description

technical field [0001] The invention relates to antenna technology and terahertz technology, in particular to microstrip slot antenna technology. Background technique [0002] Terahertz (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 wave, it has many superior characteristics and has very important academic and application value, such as THz imaging and THz spectroscopy in physics, chemistry, biomedicine, astrono...
