Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, in a first aspect, the present invention provides an antenna assembly, including: a printed circuit board 610;
a plurality of pads 620 disposed at intervals on the printed circuit board 610;
a plurality of metal lines 630 connected end to end in sequence, wherein the end of the joint of two adjacent metal lines 630 is connected with the pad 620;
the metal lines 630 are tilted to a side away from the printed circuit board 610 such that the length of the metal lines 630 between two adjacent pads 620 is greater than the projected length of the metal lines 630 on the printed circuit board 610.
Because the magnitude of the frequency affects the penetration rate and the diffraction of the signal of the antenna assembly 600, the smaller the frequency, the better the penetration rate and the diffraction of the signal of the antenna assembly 600, and because the wavelength and the frequency of the antenna are in inverse proportion, the length of the antenna needs to be increased as much as possible to reduce the frequency, thereby increasing the penetration rate and the diffraction of the signal of the antenna assembly 600; therefore, a plurality of pads 620 and a plurality of metal wires 630 are spaced from each other on the printed circuit board 610, the end of the joint of two adjacent metal wires 630 is connected to the pad 620, the metal wires 630 are tilted away from the printed circuit board 610, so that a gap is formed between the metal wires 630 and the printed circuit board 610, and the length of the metal wires 630 between two adjacent pads 620 is greater than the distance between two adjacent pads 620, the length of the metal wires 630 is increased because the metal wires 630 are tilted away from the printed circuit board 610, the plurality of metal wires 630 form an antenna, the length of the antenna is increased because the length of a single metal wire 630 is increased, and under the condition that the required length of the whole antenna is not changed, the area of the antenna on the plane of the printed circuit board 610 is relatively reduced because the length of the single metal wire 630 is increased, so that the antenna assembly 600 provided by the present invention can ensure better penetration rate and diffraction performance, the antenna size is also reduced.
The embodiment of the present invention provides an antenna assembly 600, which provides electric energy to the antenna assembly 600 through the battery module 300 when in use.
With respect to the metal wires 630 on the antenna assembly 600, the printed circuit board 610 has a first surface 611 and a second surface 612 disposed opposite to each other, and specifically, the side of the printed circuit board 610 facing the battery module 300 is the first surface 611, and the side facing away from the battery module 300 is the second surface 612.
As shown in fig. 1, specifically, the metal wire 630 is disposed on the first surface 611 of the printed circuit board 610, and the metal wire 630 is tilted to a side away from the first surface 611 of the printed circuit board 610, so that a gap is formed between the metal wire 630 and the printed circuit board 610, and thus the length of the metal wire 630 between two adjacent pads 620 is greater than the distance between two adjacent pads 620. Since the metal wires 630 are tilted toward the side away from the first surface 611 of the printed circuit board 610, and the first surface 611 is the side of the printed circuit board 610 facing the battery module 300, in order not to affect the installation of the metal wires on the first surface 611, a space is provided between the battery module and the first surface 611 of the printed circuit board, so that even if the metal wires 630 are tilted toward the side away from the first surface 611 of the printed circuit board 610.
As shown in fig. 2, specifically, the metal lines 630 are disposed on both the first surface 611 and the second surface 612 of the printed circuit board 610, and the metal lines 630 are tilted toward the first surface 611 and the second surface 612 facing away from the printed circuit board 610, so that a gap is formed between the metal lines 630 and the printed circuit board 610, and thus the length of the metal lines 630 between two adjacent pads 620 is greater than the distance between two adjacent pads 620. Specifically, the pad corresponding to the metal wire 630 is provided with a via hole 640 for conducting the first surface 611 and the second surface 612 at the position of the printed circuit board 610 where the pad 620 is located on the first surface 611 and the second surface 612 of the printed circuit board 610, and a conductor is arranged in the via hole 640 for conducting the pads 620 on both sides of the first surface 611 and the second surface 612.
As shown in fig. 3, specifically, the metal wire 630 is disposed on the second surface 612 of the printed circuit board 610, and the metal wire 630 is tilted to a side away from the second surface 612 of the printed circuit board 610, so that there is a gap between the metal wire 630 and the printed circuit board 610, and thus the length of the metal wire 630 between two adjacent pads 620 is greater than the distance between two adjacent pads 620. Also, since the metal wires 630 are tilted toward the side away from the first surface 611 of the printed circuit board 610 and the first surface 611 is the side of the printed circuit board 610 facing the battery module 300, in order not to affect the installation of the metal wires 630 on the first surface 611, a certain space is provided between the battery module 300 and the first surface 611 of the printed circuit board 610, so as to satisfy even if the metal wires 630 are tilted toward the side away from the first surface 611 of the printed circuit board 610.
As an example, the wire bonding technology (wire bonding) is used to continuously connect the metal wire 630 to the pad 620 of the printed circuit board 610, so that the metal wire 630 can be continuously extended to reach the length requirement of the antenna, and the frequency of a general capsule endoscope is 433MHz, the wavelength is 1/4 wavelength, and therefore the required length of the antenna is 175 mm. If the metal lines 630 are attached to the surface of the printed circuit board 610, and there is no gap between the metal lines 630 and the printed circuit board 610, under the condition that the length of the whole antenna is 175mm, the area of the antenna on the plane of the printed circuit board 610 is relatively increased, and the size of the antenna is also increased in order to ensure better penetration and diffraction of the antenna assembly 600.
In order to reduce the size of the antenna, the length of the metal line 630 is 1.5 times to 2 times the distance between two adjacent pads 620.
The length of the metal wire 630 can be increased to 1.5 times or 2 times the distance between the pads 620 as required, and if the length of the metal wire 630 is increased to 2 times the distance between the pads 620, that is, the length of a single metal wire 630 is increased, the area of the antenna on the plane of the printed circuit board 610 can be reduced appropriately; if the length of the metal line 630 is increased to 1.5 times the distance between the pads 620, which is relatively smaller than 2 times, but the length of the individual metal line 630 is also increased, which is a suitable increase in the area of the antenna in the plane of the printed circuit board 610 relative to 2 times.
Because the metal wire 630 is tilted away from the printed circuit board 610, the length of the bent metal wire 630 can be 1.5-2 times longer than the length of the metal wire 630 directly attached to the printed circuit board 610, so the area of the plane of the printed circuit board 610 occupied by the bent metal wire 630 can be reduced, the plane formed by the X axis and the Y axis is the plane of the printed circuit board 610, and the vertical space occupied by the tilted height of the metal wire 630 from the printed circuit board 610 is not large, so the Z axis is relatively shortened, and the Z axis is perpendicular to the printed circuit board 610.
Optionally, a plurality of metal lines 630 connected end to end in sequence form a multi-segment line.
The metal lines 630 connected end to end are formed into various shapes, such as polygon or spiral, or irregular patterns, as long as the length of the antenna can be increased as much as possible, thereby ensuring the penetration rate and diffraction of the antenna.

As shown in fig. 4a to 4g, the shape is not limited to the above-mentioned saw-tooth wave shape, square shape, sine wave shape, spiral shape, and loop shape, but may be any shape that can secure the overall length of the antenna.
Optionally, comprising: the metal lines 630 include one or more of the following: gold wire, copper wire and aluminum wire.
Of course, the metal lines 630 may be gold lines, copper lines, aluminum lines, or a mixture thereof, as long as the transmittance and diffraction of the antenna connected by the metal lines 630 are not affected.

Because the utility model discloses when the antenna module 600 that the first aspect provided can guarantee better penetrability and diffraction, still reduced the antenna size, consequently will reduce the size of capsule endoscope to make the patient change and swallow.
Specifically, the housing may be transparent, partially transparent, or partially opaque in the entire casing 100, as long as it ensures that the position of the image acquisition module 500 for acquisition is transparent, and specifically, the transparent portion of the casing 100 may be made of plastic, or may be made of any other transparent material, which is nontoxic, harmless, and easy to swallow; the opaque portion of the housing 100 may be made of any opaque, nontoxic, harmless, and easily swallowable material.
