Abstract

The invention discloses a conformal broadband circularly polarized capsule antenna. The conformal broadband circularly polarized capsule antenna comprises a metal member, a flexible dielectric substrate and a metal probe. The flexible dielectric substrate gets close to the inner wall of the capsule housing, and the metal member is conformally attached at one side, facing the inner side, of the flexible dielectric substrate. The metal member comprises a frame-shaped metal piece, a first metal strip and a second metal strip. The first metal strip is located in the frame of the frame- shaped metal piece, and one end of the first metal strip is connected with the frame-shaped metal piece. The second metal strip is located in the frame of the frame-shaped metal piece, and is separated from theframe-shaped metal piece and the first metal strip. One end of the metal probe is connected with the metal member, and the other end thereof passes through the flexible dielectric substrate to reach the back surface of the flexible dielectric substrate. The conformal broadband circularly polarized capsule antenna employs the first metal strip and the second metal strip to disturb the field insidethe antenna to allow the antenna has a good circular polarization performance and a wide circular polarization bandwidth so that receiving and sending of signal data are more reliable.

Description

technical field [0001] The invention relates to the technical field of wireless medical equipment, in particular to a conformal broadband circularly polarized capsule antenna for a wireless capsule endoscope. Background technique [0002] Wireless Capsule Endoscopy (WCE) is an endoscope made in the shape of a capsule. As a wireless implant device, it has been widely used in medical diagnosis and treatment. A typical wireless capsule endoscope usually includes a transparent housing, a light source, an imaging element, a sensor, a battery, a transceiver module, and a capsule antenna, etc. The wireless capsule endoscope can enter the human body through oral administration, and rely on digestive tract peristalsis to move in the digestive tract to spy on the health status of the digestive tract. Compared with the traditional endoscope, it has the advantages of convenient inspection, no trauma, no wires, no pain, no cross infection, and no influence on the normal work of the exam...
