Abstract

The invention proposes a terahertz double-frequency antenna based on the CMOS integrated circuit technology. A rectangular radiation patch microstrip antenna is improved, thereby enabling the length L of an antenna radiation patch to be corresponding to one frequency resonance and enabling the width W of the patch to be corresponding to the other frequency resonance. The feeding at one corner of a diagonal line of the rectangular radiation patch is carried out, and at this moment the antenna excites two direction modes: TM01 and TM10 at the same time, thereby enabling one radiation patch to work at two terahertz frequencies. One angle of the diagonal line of terahertz double-frequency rectangular radiation patch antenna is connected with a grid electrode of a transistor through a through hole for work. According to the relation between the work frequency f and the length L of a radiation unit, the design requirements for the length and width of the antenna radiation patch at a needed work frequency can be determined. One point on the diagonal line of the rectangular radiation patch is selected as a feed point, and a mode of coaxial feed is employed.

Description

technical field [0001] The invention relates to the field of terahertz signal detection, and further relates to a detector structure using a dual-frequency antenna as a signal receiving component, which can realize dual-band response. Background technique [0002] Terahertz is a transition region between microwave and infrared, with unique properties such as strong transmission and high resolution; terahertz detection technology has great potential in broadband communication, radar, medical imaging, non-destructive testing, security inspection and other fields. important application prospects. At present, terahertz technology mainly focuses on terahertz sources, terahertz detection and application fields. Among them, obtaining a room-temperature terahertz detector with high signal-to-noise ratio, good sensitivity, and wide-band response is the key to promoting the development of terahertz technology applications. The CMOS terahertz detector based on the integrated circuit ...
