Abstract

The invention discloses a detuning feed slot antenna based on a resonance tunneling mechanism, and belongs to the field of antennas. The detuning feed slot antenna based on the resonance tunneling mechanism comprises a detuning feed slot antenna body and a RTD. The resonance tunneling diode serves as an excitation device and is used for generating terahertz waves, and the detuning feed slot antenna body serves as an electromagnetic wave transmitting device and is used for transmitting the terahertz waves generated by the resonance tunneling diode out. The top electrode of the RTD is connected with a left electrode of the detuning feed slot antenna body through a heat sink, and the bottom electrode of the RTD is connected with the right electrode of the detuning feed slot antenna body. The detuning feed slot antenna based on the resonance tunneling mechanism has important application in the fields of superspeed data link transmission, wireless communication, military and national defense and the like.

Description

technical field [0001] The present invention relates to antenna technology and terahertz technology, in particular to offset feeding 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, 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...
