Description

Technical Field

[0001] The present invention relates to the field of antenna technology, and in particular to a wearable antenna. Background Art

[0002] Early wearable antennas were mainly in the form of wire antennas, but wire antennas are difficult to adapt to deformation. This led to the emergence of wearable antennas based on textile materials, which can maintain stable radiation performance under different bending conditions.

[0003] With advances in flexible electronics and metamaterials, wearable antennas are becoming thinner, lighter, and more comfortable. In terms of applications, wearable antennas have permeated every aspect of our lives, including healthcare, sports fitness, disease management, military, and security services. With the rise of the Internet of Things, wearable antennas need to integrate multiple wireless communication technologies to fully realize their potential and interoperate with other devices. To meet evolving application needs, researchers are developing ultra-wideband and reconfigurable antennas. These antennas can switch between different frequencies, radiation patterns, and polarization characteristics to adapt to different operating environments, thereby enhancing the intelligence and adaptability of wearable devices. Through continuous technological innovation, wearable antennas are moving towards higher performance, more functionality, and greater adaptability.

[0004] The presence and movement of the human body increase the polarization loss factor, reducing communication quality and data transmission accuracy. Furthermore, wearable antenna performance varies depending on where they are placed on the body. Radiation from the antenna to the human body is also a concern, ensuring that the SAR value is below international standards. Adding a head-mounted antenna can mitigate the low communication efficiency caused by human movement and reduce radiation exposure by not attaching the antenna to the body. Intelligent antenna designs that switch between different frequencies and polarization characteristics can meet a wider range of needs and are particularly important for innovation and development in the antenna and communications fields. Summary of the Invention

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] Reference Figures 1 to 5 A wearable antenna of this embodiment includes an upper vibrator group and a lower vibrator group, a dielectric box, a connecting support, a dielectric support, a top cover, a dielectric shell, a metal belt, a radio frequency cable, a circular polarizer, a metal support rod and a multi-angle metal strip.

[0037] When using a single low-frequency directional antenna:

[0038] The low-frequency directional antenna is designed around a dielectric shell made of non-metallic materials, either hard or soft. When the dielectric shell is soft, the lower oscillator is designed to be made of soft metal, in close conductive contact with other metals, and attached to the outer surface of the dielectric shell or clamped inside it. When the dielectric shell is hard, the lower oscillator can also be made of hard metal, in close conductive contact with other metals, and attached to the surface of the dielectric shell or clamped inside it. The dielectric shell is semicircular in shape with a concave interior, allowing it to be worn as a hat or helmet for ease of use.

[0039] Two pairs of lower dipoles—lower dipole a, lower dipole b, lower dipole c, and lower dipole d—are tightly attached to the outer layer of the dielectric shell. Made of copper, their thickness is adjusted based on the softness or hardness of the dielectric shell, ensuring the dipoles do not touch each other. The gradient width, length, and spacing between the dipoles can be set and fixed based on the antenna's operating frequency and electrical specifications. Adjustable dimensions are also available, allowing for quick adjustment of dipole size to accommodate changing antenna operating frequencies.

[0040] Two welding pieces are provided at the top of the lower dipole group, and two equal-phase cables are simultaneously passed through the hole in the dielectric shell directly below the inner core hole of the welding piece from the front side of the top of two adjacent lower dipoles (lower dipole c and lower dipole d), so that each cable shielding net is in close conductive contact with the outer surface of the lower dipole c and the lower dipole d respectively; according to the operating frequency and electrical indicators of the antenna, the reserved part of the dielectric between the cable inner core and the cable shielding net is adjusted to isolate the cable inner core and the cable shielding net to prevent short circuit; each cable inner core is in close conductive contact with the welding piece; the other end face of each welding piece is in close conductive contact with the lower dipole a and the lower dipole b; a dielectric film is added between the two welding pieces for non-contact isolation between the two welding pieces to prevent short circuit.

[0041] The soldering lug is made of metal, with one end extending through the cable core hole and positioned directly above it. Its width, length, and distance from the antenna element can be set and fixed based on the antenna's operating frequency and electrical specifications. Adjustable dimensions are also available, allowing for quick adjustment of the lug's size to accommodate changing antenna operating frequencies. The lug is made of hard metal and resists bending, which could affect the antenna's reception and transmission of RF signals.

[0042] The dielectric shell is topped with a non-metallic cover to prevent the low-frequency directional antenna feed point from contacting the outside world. Metal is applied to the outer surface of the cover to create a tight fit, with the thinner the metal, the better. The height of the dielectric shell and the size of the metal covering it can be customized based on the antenna's operating frequency and electrical specifications. Adjustable dimensions are also possible, allowing for quick adjustment of the cover and metal covering to accommodate changing antenna operating frequencies.

[0043] If the dielectric shell is made of a soft material, the top cover is fixed to the dielectric shell by gluing or sewing, and sealing or shielding is used to prevent the connection between the welding piece inside the top cover and the lower oscillator from contacting rainwater, so as not to affect the use of the antenna in rainy weather conditions; if the dielectric shell is made of a hard non-metallic material, the top cover is fixed to the dielectric support on the dielectric shell by dielectric screws, and sealing or shielding is still used to prevent rainwater from entering the top cover and affecting the use of the antenna.

[0044] A metal strip is added to the bottom of the dielectric shell, acting as a reflector for low-frequency directional antennas. Its function is similar to the metal base plate of a conventional directional antenna and can be attached to the outer surface of the dielectric shell or clamped inside it. The flexibility of the metal strip can be adjusted based on the hardness of the dielectric shell, similar to the low-frequency directional antenna element.

[0045] The distance between the metal strip and the lower oscillator, as well as the width of the metal strip, are related to the antenna's operating frequency and electrical specifications. By adjusting the metal strip diameter and the distance between the oscillators, the antenna can be adapted to changing operating frequencies.

[0046] The low-frequency directional antenna RF cable transmits power through the interior of the dielectric shell or on its inner surface, extending beyond the shell's edge. Horizontal, vertical, or circular polarization is optional. For horizontal and vertical polarization, the communication equipment can be directly connected to the RF cable. For circular polarization, two equiphase RF cables are simultaneously connected to a circular polarizer and secured to the exterior or interior of the dielectric shell. Alternatively, the circular polarizer can be integrated with the RF cable and secured to the shell in printed circuit form. Once circular polarization is achieved, an external RF cable can be connected.

[0047] The single low-frequency directional antenna design allows the antenna and dielectric shell to be completely attached or placed inside the dielectric shell, with only the top cover exposed. Its main beam points toward the sky, enabling communication with airborne communication equipment. It can also be used in Beidou, GPS, 5G, IoT, and other applications, meeting daily needs. The antenna can be used as a hat or helmet, and the connected communication device can be worn on clothing or placed in a backpack. Powered by a battery pack, it allows for communication at any time.

[0048] When adding a high-frequency directional antenna:

[0049] Adding a high-frequency directional antenna to the top cover of the dielectric shell can meet a wider range of wearable antenna applications. The high-frequency directional antenna consists of two pairs of vibrators: upper vibrator a, upper vibrator b, upper vibrator c, and upper vibrator d. Made of copper, the vibrators are rigid and unbendable, and they do not touch each other. The gradient width, length, and spacing between the two vibrators can be set and fixed based on the operating frequency and electrical specifications. Adjustable dimensions can also be configured for quick adjustment to accommodate changes in the antenna's operating frequency.

[0050] The tops of the two pairs of upper oscillators of the high-frequency directional antenna are connected to two equal-phase cables respectively; the two equal-phase cables are simultaneously passed through the tops of two adjacent oscillators (upper oscillator a and upper oscillator d), so that the shielding net of each cable is in close conductive contact with the outer surface of the upper oscillator a and upper oscillator d respectively; the inner core of each cable is in close conductive contact with the upper oscillator c and upper oscillator b on the opposite side; a dielectric film is added at the crossing part of the cables to be used for non-contact isolation of the two RF cables to prevent short circuits.

[0051] The two pairs of upper oscillators of the high-frequency directional antenna are fixed and enclosed in a dielectric box; the dielectric box is fixed to the connecting support by dielectric screws, and rainwater is prevented from entering the dielectric box by sealing or shielding, so as not to affect the normal operation of the antenna.

[0052] The connecting support and vibrator are connected to the dielectric housing assembly. The connecting support and dielectric housing can be considered a single-piece structure, housing a rotary joint, a motor, and a battery that powers the motor. When the high-frequency directional antenna is used with horizontal or vertical polarization, the motor is not required in the connecting support, and the rotary joint and motor can be removed to save costs. Two equiphase RF cables can be directly transmitted through the dielectric support and the holes in the dielectric housing to the external interface.

[0053] When the high-frequency directional antenna is used with circular polarization, two equiphase RF cables can be directly connected to the circular polarizer. The circular polarizer can be embedded in the bottom of the dielectric shell.

[0054] High-frequency directional antennas can also achieve circular polarization by rotating the vibrator through a motor. By controlling the direction of rotation of the motor, the antenna can be polarized in both left-hand and right-hand circular polarization modes. The tail ends of the two equal-phase RF cables connecting the vibrator are connected to a rotating joint, and the other ends of the rotating joint are connected to two corresponding equal-phase RF cables. When the motor is turned on, the rotating joint rotates with the motor to prevent the RF cables from twisting. The two cables pass through the side of the motor, into the dielectric support, through the upper vibrator cable vias reserved in the dielectric shell, and are connected to a power divider, which increases the antenna power value and enhances the signal transmission distance.

[0055] The dielectric support is made of a hollow dielectric tube. The RF cable passes through the support and is screwed onto the top cover. The dielectric support height can be controlled and fixed according to the antenna's operating frequency and electrical specifications. It can also be configured to be adjustable, allowing for quick adjustment of the antenna's electrical specifications to meet changing operating frequencies. The cable is embedded within the dielectric shell, with the RF connector exposed on the outer edge for easy connection to communications equipment.

[0056] The high-frequency directional antenna uses the metal layer on the top cover as a directional antenna reflector. The metal material dimensions of the top cover can be adjusted based on the operating frequency and corresponding electrical specifications of the high-frequency directional antenna and the low-frequency directional antenna in the dielectric shell. The dimensions can also be set to be adjustable to accommodate changes in the antenna's operating frequency. If the antennas meet the electrical specifications, the upper and lower directional antennas can be used together.

[0057] The wearable antenna uses two directional antenna modes: a high-frequency directional antenna on the upper portion and a low-frequency directional antenna on the lower portion. This design allows the two antennas to operate together, with their main beams pointing in the same direction, toward the sky. The high-frequency directional antenna is small and mounted on the upper portion of the dielectric housing, without obstructing the larger low-frequency directional antenna below. Both directional antennas can communicate with airborne communication equipment and can be used in applications such as Beidou, GPS, 5G, and the Internet of Things, meeting daily needs. When the dielectric housing is used as a hat or helmet, the communication devices can be connected to the antennas separately via RF cables and operate simultaneously, or they can be switched using an RF switch. The communication device can be worn on clothing or placed in a backpack, powered by a battery pack, and ready for communication at any time.

[0058] When adding an omnidirectional antenna:

[0059] In addition to adding a high-frequency directional antenna to the top cover of the dielectric shell, you can also add an omnidirectional antenna to meet the needs of short-distance and shortwave radio communications.

[0060] The antenna's metal support rod, the omnidirectional antenna element, is made of lightweight, flexible, elastic, and durable metal. Its lower end is screwed to the top cover, and its upper end is screwed to a multi-angle metal strip. This effectively reduces the element's size, facilitating normal use while the wearable antenna is in motion. The length and width of the metal support rod and strip are adjustable, allowing for easy use of the omnidirectional antenna's operating frequency.

[0061] The cable core is in close contact with the bottom of the metal support rod, while the cable shield is slightly spaced from the rod, ensuring they are secure and non-contacting, preventing short circuits. The cable is routed along the inner sidewall of the dielectric housing or placed inside the housing. When the cable and the metal strip are aligned, a probe is passed through the housing to ensure close contact between the cable shield and the metal strip. In this configuration, the metal strip can serve not only as a reflector for low-frequency directional antennas but also as a ground plane for monopole omnidirectional antennas.

[0062] The cable is buried in the dielectric shell and can also be routed inside the dielectric shell. The radio frequency interface is exposed on the outer edge of the dielectric shell, which is convenient for connection with shortwave radio equipment.

[0063] When the dielectric shell is used as a hat or helmet, the communication device can be connected to the antenna separately via an RF cable and operate simultaneously, or it can be switched between uses using an RF switch. The radio device can be worn on clothing, placed in a backpack, or slung across the back. It is powered by a battery pack and can make voice calls at any time.

[0064] The high-frequency directional antenna and omnidirectional antenna can be removed from the antenna and placed in the interlayer of the packaging box. The antenna is stored in the packaging box for easy storage and carrying.

[0065] Brief working principle of the present invention:

[0066] This invention's operating principle is based on conventional directional and omnidirectional antennas. The antenna is placed or attached to a dielectric shell, typically a hat or helmet, and worn on the head. It can be used in three configurations: low-frequency directional antennas, combined high- and low-frequency directional antennas, and omnidirectional and low-frequency directional antennas. Both high- and low-frequency directional antennas are available in three polarization modes: horizontal, vertical, and circular.

[0067] It should be noted that the above description is only an example of a preferred application of the present invention and is not intended to limit the scope of protection of the present invention. Any technical solution that adopts equivalent replacement or equivalent transformation is within the scope of protection of the present invention.
