Detailed ways

Advantages of the present invention will be further clarified below with reference to the accompanying drawings and specific embodiments.

1 is a schematic structural diagram of a mobile terminal 100 having a secondary antenna unit 120 in accordance with a preferred embodiment of the present invention. In this embodiment, the mobile terminal 100 includes a housing 110 formed at the outermost portion. The basic shape of the housing 110 is an overall shape of the mobile terminal 100, and an antenna assembly disposed inside the housing 110. The antenna assembly is based on The 2G, 3G, 4G, 5G and wireless signal protocols are equivalent to external connections, and may be cellular network antennas, GPS antennas, Bluetooth antennas, WIFI antennas, and the like. In the structural arrangement, the antenna assembly includes a main antenna unit disposed on the upper side and/or the lower side of the mobile terminal 100, that is, at the top end and/or the tail end of the housing 110, the main antenna unit is disposed. In addition to the main antenna unit, the antenna assembly further includes a sub-antenna unit 120 that is disposed on the left side, the right side, or the left and right sides of the mobile terminal 100. By the configuration of the primary antenna unit supplemented by the secondary antenna unit 120, when a signal difference occurs in the primary antenna unit, the secondary antenna unit 120 can be used as a backup antenna as a transmission and reception signal. At a position where the auxiliary antenna unit 120 is disposed, an antenna strip area is disposed correspondingly, and the set position of the antenna strip area faces the auxiliary antenna unit 120 in the forward direction, and the size of the antenna strip area is configured such that the projective area thereof is larger than the auxiliary antenna. The projective area of unit 120. The projective area referred to herein is the area obtained after projecting into the antenna strip area in a direction orthogonal to the antenna strip area, that is, the area obtained by projection in a positive direction, the antenna strip area is larger than The auxiliary antenna unit 120 is such that the antenna strip area is not only larger than the auxiliary antenna unit 120 as a whole, but is substantially at the corresponding position of the auxiliary antenna unit 120, or is located outside the corresponding position of the auxiliary antenna unit 120. The auxiliary antenna unit 120 can normally transmit and receive signals through the antenna strip area.

With the above configuration, when the user taps the mobile terminal 100, the user's usage habit is to hold the left and right parts of the current device, and the horizontally disposed mobile terminal 100 is originally located at the top and the end of the main antenna unit. In the left and right parts, the user actually holds the part of the mobile terminal 100 that is provided with the main antenna unit, so that the signal transmission and reception of the main antenna unit is blocked. At this time, the auxiliary antenna unit 120 also naturally changes from the left side and the right side of the original mobile terminal 100 to the upper side and the lower side in the current state position, and the hand portion held by the user does not contact the auxiliary antenna unit 120, and It can replace the main antenna unit for normal signal transmission and reception.

Further, the mobile terminal 100 is provided with a display screen 130 serving as a content for displaying an application. When the mobile terminal 100 is placed transversely, the display screen 130 is substantially at an intermediate position of the entire mobile terminal 100, and the auxiliary antenna unit 120 and the antenna strip area are It is then located near the middle of the display screen 130, and is substantially symmetrical about the central axis of the display screen 130. The advantage of the configuration is that when the mobile terminal 100 is held in the horizontal state, the finger moves to the middle of the mobile terminal 100 except for the palm of the mobile terminal 100. Therefore, the auxiliary antenna unit 120 needs to be as far as possible. The layout is arranged close to the middle to ensure that the user's fingers do not block the auxiliary antenna unit 120.

In a preferred or alternative embodiment, the auxiliary antenna unit 120 is in the form of an elongated strip attached to the inner surface of the antenna strip area to prevent the antenna strip area from being too wide and cannot be completely installed in the narrowly constructed mobile terminal 100. Further, the auxiliary antenna unit 120 is configured to ensure an input/output function, and includes a resonant circuit. The resonant circuit is composed of a radiator and a feeding end, wherein the radiator is used for transmitting and receiving signals, and the feeding end forms an input and output of the auxiliary antenna unit 120. End, to implement the signal transceiving function of the auxiliary antenna unit 120.

In order to further prevent the signal transmission and reception of the auxiliary antenna unit 120, the antenna strip area is made of a non-metal material, and both ends thereof are rounded. Generally, the metal material greatly affects the function of the antenna. Therefore, the antenna strip area is made of a non-metal material, and can be expressed as a decorative area on the mobile terminal 100, and a metal-like surface is formed by sanding to minimize the surrounding metal portion. Differences, and thus for the user, strive to achieve an integrated visual experience of the mobile terminal 100.

A metal region is disposed on both sides of the housing 110 and disposed outside the antenna strip region. The metal region is made of a metal material, and the strength of the mobile terminal 100 is enhanced, and the aesthetics of the mobile terminal 100 can be increased. In the case where the mobile terminal 100 is placed transversely, the metal area is used as a handheld portion of the user holding the mobile terminal 100 to separate the antenna strip area.

In the case of having both the main antenna unit and the auxiliary antenna unit 120, the two can be used synchronously or asynchronously. For example, the mobile terminal 100 includes an acceleration sensor, a controller, such as a chip, and an antenna switching module, such as a functional module integrated in the chip, and the acceleration sensor is used to detect the placement state of the mobile terminal 100, for example, the current mobile terminal 100 is vertical, The controller is connected to the acceleration sensor, receives the acceleration sensor to detect the placement state of the mobile terminal 100, and sends the placement state information to the antenna switching module, and the antenna switching module is configured according to the current mobile terminal 100. State, select to use the primary antenna unit or the secondary antenna unit 120. For example, when the mobile terminal 100 is horizontally placed, its placement status information is also horizontal, and then control is switched to the secondary antenna unit 120 for primary signal transmission and reception. On the one hand, the most suitable antenna can be intelligently used according to the state of the mobile terminal 100, and on the other hand, the signal transmission speed can be accelerated, and the eligibility problem when the two parts of the antenna are used synchronously is omitted.
