Antenna device

Abstract

The present invention relates to an antenna device comprising: an antenna component. The antenna component comprises: an isolation layer; an antenna layer adhered to the isolation layer through a pressing method, wherein the antenna layer comprises an array antenna which comprises a transmitting end array antenna and a receiving end array antenna; an antenna transmitting device positioned at one end of the transmitting end array antenna; an antenna transmitting terminal positioned at the other end of the transmitting end array antenna; an antenna receiving device located at one end of the receiving end array antenna; an antenna receiving terminal positioned at the other end of the receiving end array antenna; an anti-oxidation protection layer which covers the surface of the antenna layer; an adhesive layer adhered to the anti-oxidation protection layer; and a reinforcing layer aluminum foil adhered to the adhesive layer.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an antenna device. Background technique [0002] At present, electronic devices are developing in the direction of miniaturization and miniaturization. Due to size limitations, the antenna components inside electronic devices have problems such as short signal transmission distance, unstable transmission signals, and unclear transmission pictures. [0003] Capsule gastroscopy is a device that uses software to precisely control the external magnetic field in real time to control the movement of the capsule robot in the stomach, change the posture of the capsule, and take photos of key lesions at the required angle, so as to achieve a comprehensive observation of the gastric mucosa and make a diagnosis. Due to the small size of the capsule gastroscope itself (about 1 cm in diameter and about 3 cm in length) and no shielding device, the antenna of the capsule ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned communication technologies have the problem of short transmission distance. The effective distance of Bluetooth communication is 2-5m, the effective distance of Zigbee communication is 200-300m, and the effective distance of Lora communication is 1500-4000m.

Capsule gastroscopy based on the above-mentioned communication technology cannot realize long-distance signal transmission. If the capsule gastroscope product based on the above-mentioned communication technology is used for physical examination, the patient needs to enter the hospital or a clinic with medical qualifications in person.

The communication bandwidth of the antenna based on the above-mentioned communication technology is small, the transmission rate is slow, and it cannot transmit large-capacity data, so the capsule gastroscope based on the above-mentioned communication technology cannot obtain high-definition photos for subsequent diagnosis

Moreover, the antennas used in traditional micro-miniature devices usually have no shielding measures and are susceptible to environmental interference

[0005] Aiming at the problem that the antenna of traditional capsule gastroscope cannot perform stable long-distance signal transmission and large-capacity data transmission, a new research idea is needed to develop a capsule gastroscope antenna with small size, long transmission distance, stable transmission signal and large transmission data capacity device
