Embodiment 2

[0085] Embodiment 2: A wearable diversity antenna with four antenna units and a body bag as the antenna unit carrier

[0086] Fig. 5 is a schematic diagram of a wearable diversity antenna layout with a body bag as the carrier of the antenna unit as the second embodiment provided by the present invention, which has four rectangular microstrip patch antenna units with orthogonal polarization directions , in the figure, 1 is the antenna unit, 2 is the antenna ground corresponding to the antenna unit 1 (using a metal braided cloth sheet), and 3 is the antenna unit carrier (a pocket).

[0087] Both the antenna unit 1 and the antenna ground 2 are located on the wearable antenna unit carrier 3, and the distance between the antenna unit 1 and the human body is greater than the distance between the antenna ground 2 and the human body, and the main radiation direction of the antenna unit 1 points to the side away from the human body. When the wearable diversity antenna of the wireless c...

Embodiment 3

[0091] Embodiment 3: A wearable diversity antenna with two antenna units and a watch chain as the antenna unit carrier

[0092] Fig. 7 is a schematic diagram of the layout of a wearable diversity antenna with a watch chain as the carrier of the antenna unit according to the third embodiment of the present invention. It has two antenna units. In the figure, 1 is the antenna unit and 2 is the antenna unit. Antenna ground corresponding to antenna unit 1 (a metal braided cloth is used), and 3 is an antenna unit carrier (a watch chain).

[0093] The antenna unit 1 and the antenna ground 2 are located on both sides of the wearable antenna unit carrier 3, and the distance between the antenna unit 1 and the human body is greater than the distance between the antenna ground 2 and the human body, and the main radiation direction of the antenna unit 1 points to a direction away from the human body. On the other hand, when the wearable diversity antenna of the wireless communication termi...

Embodiment 4

[0098] Embodiment 4: A wearable diversity antenna with two antenna units and an armband as the antenna unit carrier

[0099] Fig. 8 is a schematic layout diagram of a wearable diversity antenna with an armband as the carrier of the antenna unit according to the fourth embodiment of the present invention. It has two antenna units in an orthogonal configuration. In the figure, 1 is the antenna unit , 2 is the antenna ground corresponding to the antenna unit 1 (a metal woven cloth is used), and 3 is the antenna unit carrier (a kind of armband).

[0100] Both the antenna unit 1 and the antenna ground 2 are located on the inner and outer sides of the wearable antenna unit carrier 3, and the distance between the antenna unit 1 and the human body is greater than the distance between the antenna ground 2 and the human body, and the main radiation direction of the antenna unit 1 points away from the human body. On one side, when the wearable diversity antenna of the wireless communicat...

Abstract

This invention provides a dressable diversity antenna device for wireless communication mobile terminal, which comprises N (N is positive integer and not less than one) antenna units and corresponding M (M is positive integer and not less than one) antenna grounds that can be combined, and a dressable antenna unit carrier (waistband or waist pack); the primary radiation direction points toward back direction to human, all antennas connect to corresponding transmitter or receiver by feeding device. The invention has no radiation damage, easy to conformal with people body, and can be used widely to obtain polarization diversity, angle diversity or space diversity, or time-space code, or MIMO wireless communication system.

Description

technical field [0001] The invention belongs to the technical field of wireless communication diversity antennas, in particular to the technology of wearable diversity antennas for wireless communication terminals. Background technique [0002] With the rapid development of wireless communication, the number of users is increasing day by day, and the data service is growing continuously. The wireless communication system of single-antenna transceiver is facing severe capacity bottleneck test. It is necessary to further improve the capacity and quality of the current wireless communication system, and seek new Technical solutions. Multiple transmission and multiple reception (MIMO) technology is a new wireless communication technology that utilizes multiple transmitting and multiple receiving antennas. Its transmitted data stream is separated into multiple sub-data streams, which are transmitted simultaneously at the same frequency through different antennas after modulation....
