Embodiment 1

[0035] combine 1 and figure 2 As shown, the embodiment of the present invention provides a liquid metal-based antenna 1, which includes a control unit 11, an antenna feeder 9, a support sleeve 5, an air pressure balance chamber 8, a base 2, and two components with inverse piezoelectric The flexible side plate 3 is made of piezoelectric material with high-efficiency effect, the top of the air pressure balance chamber 8 is provided with a vent, the bottom is connected with the top of the support sleeve 5, the left and right sides of the base 2 are provided with openings, and the two flexible sides The plates 3 are respectively covered on the corresponding openings to form a cavity together with the base 2. The bottom of the support sleeve 5 communicates with the cavity, the cavity is filled with liquid metal 4, and one end of the antenna feeder 9 is inserted into the cavity. It is located at the bottom of the base, and the other end is electrically connected to the transceiver ...

Embodiment 2

[0045] Such as Figure 4 As shown, the present invention also provides an antenna radiation symmetric oscillator, which includes a plurality of antenna oscillators parallel to each other, each antenna oscillator includes two antennas 1 based on liquid metal as described above, and two antennas 1 based on liquid metal Metal antennas 1 are set up and down opposite to each other.

[0046] The structure and principle of the liquid metal-based antenna 1 in this embodiment are the same as those in Embodiment 1, and will not be repeated in this embodiment. By receiving and transmitting the same frequency signal at the same time through multiple antenna elements, multiple radiation circles can be formed in the horizontal direction, which can greatly increase the radiation power and make it suitable for ultra-long-distance microwave signal transmission.

Embodiment 3

[0048] The present invention also provides a method for preparing an antenna 1 based on liquid metal, the method comprising the following steps:

[0049] The two flexible side plates 3 are respectively bonded to the openings on the left and right sides of the base 2 to form a cavity together with the base 2;

[0050] The bottom end of the support sleeve 5 is bonded to the top of the base 2 so that the support sleeve 5 communicates with the cavity.

[0051] Filling the support sleeve 5 with liquid metal 4 and alkaline sealing liquid 6 sequentially, and covering the top of the support sleeve 5 with an acrylic resin film 7;

[0052] bonding the air pressure balance chamber 8 to the top of the support sleeve 5, so that the support sleeve 5 communicates with the air pressure balance chamber 8;

[0053] Insert one end of the antenna feeder 9 into the bottom of the base so that the antenna feeder 9 is in contact with the liquid metal 4; electrically connect the other end of the ante...

Abstract

The invention relates to the technical field of wireless communication, and provides a liquid-state metal-based antenna and a preparation method therefor, and an antenna radiation symmetrical vibrator. The antenna comprises a control unit, an antenna feeder line, a supporting sleeve, an air pressure balance cavity, a base and two flexible side plates which are prepared from a piezoelectric material with an inverse piezoelectric effect; a ventilating opening is formed in the top of the air pressure balance cavity, and the bottom is connected with the top of the supporting sleeve; openings are formed in the left and right sides of the base respectively, and the two flexible side plates cover the corresponding openings to form a hollow cavity with the base in a jointly surrounding manner; thebottom of the supporting sleeve is connected with the hollow cavity, and the hollow cavity is filled with liquid-state metal; one end of the antenna feeder line is inserted in the bottom of the basewhile the other end is electrically connected with a transceiver; and the control unit is electrically connected with the flexible side plates and used for applying voltages of corresponding values tothe flexible side plates according to a to-be-received frequency signal. The liquid-state metal-based antenna is small in size, convenient to carry, high in radiation gain, electromagnetically compatible, large in frequency band width, and high in impedance matching.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a liquid metal-based antenna, a preparation method thereof, and an antenna radiation symmetric vibrator. Background technique [0002] An antenna is a device used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, must rely on antennas to work. [0003] However, with the rapid development of the electronics and wireless communication industries, the system has higher and higher requirements for equipment miniaturization, high gain, multi-band and other indicators. Therefore, the development direction of wireless communication systems must be miniaturization, ultra-wideband and Diverse functions. As an essential component of a wireless transmission system, the anten...
