ANTENNA STRUCTURE FOR DUAL-LENS CAPSULE ENDOSCOPE

摘要

Disclosed is an antenna structure for a dual-lens capsule endoscope; the capsule endoscope comprises circuit modules, an antenna, a battery, and lens modules; the circuit modules are located at two ends of the capsule endoscope, respectively; the battery is located in the middle of the capsule endoscope, and the battery is electrically connected to each of the circuit modules; and there are two lens modules that are respectively located at two ends of the capsule endoscope and are electrically connected to the circuit modules, respectively. An antenna can be arranged on a peripheral surface of a PCB by employing a means of multi-layered winding, or can employ a T shape and be wound on the peripheral surface of the antenna PCB, or can employ a double-ring structure and be arranged between a third battery and the antenna PCB, or can be a strip antenna and connect the battery and the peripheral surface of the PCB. By employing the antenna structure according to the present invention, the effective length of an antenna can be increased by means of serpentine wiring or the magnetic energy ratio of a near field area can be increased by means of a ring-shaped or spiral structure and wiring, thus decreasing the impact of metal devices around the antenna on the antenna, improving the antenna radiation efficiency, and improving the stability of wireless image transmission.
