Abstract

The invention discloses a subminiature acoustic wave resonant antenna, which comprises a piezoelectric crystal structural component, a fixing device and a signal feed port, the fixing device is arranged on the piezoelectric crystal structural component and is used for fixing the piezoelectric crystal structural component; the signal feed port is arranged on the piezoelectric crystal structural component and is used for coupling a signal to the piezoelectric crystal structural component; and the piezoelectric crystal structural component is used for radiating or receiving the signal. The size of the ultra-small sound wave resonance antenna is far smaller than that of a traditional antenna, the antenna radiation efficiency is greatly improved, and therefore the technical problems that the size of an existing ultra-small sound wave resonance antenna is difficult to reduce, and consequently a very-low-frequency communication system and an ultra-low-frequency communication system are largein size, huge in power consumption and low in radiation efficiency are solved.

Description

technical field [0001] The application belongs to the technical field of very low frequency communication, and in particular relates to an ultra-small acoustic wave resonant antenna. Background technique [0002] In modern warfare, anti-submarine communication is of great significance in the field of national defense and military affairs. Very low frequency electromagnetic waves have excellent penetration and propagation performance, can penetrate seawater, and can also use the refraction of the atmospheric ionosphere for intercontinental transmission. Therefore, very low frequency electromagnetic waves have been widely used in underwater submarine communication, underwater navigation, and ground-penetrating communication. [0003] Due to the limitation of the half-wavelength resonance principle, the existing antenna has a large size, huge power consumption, and low radiation efficiency. Therefore, it is a technical problem to be solved urgently by those skilled in the art...
