Abstract: An antenna system and a mobile terminal implemented with the antenna system are provided. The mobile terminal has a metal frame and a system grounding. The antenna system has at least a first antenna module, a second antenna module, a third antenna module and a fourth antenna module. The first antenna module has a radiating body and a parasitic element coupled to the radiating body. The radiating body is configured to generate a main harmonic, and the parasitic element is configured to generate a parasitic harmonic. The first antenna module further has a first tuning circuit and a second tuning circuit. The antenna system has at least four operation modes. The antenna system of the present invention may achieve carrier aggregation of different LTE frequencies, and may be used as a MIMO antenna system.

Abstract: The present disclosure provides an item picking method, so that an item stored in a warehouse can be picked and placed in a picking vehicle. Specifically, the warehouse may be divided into one or more picking areas. A picking management device may divide a picking task for items into different picking sub-tasks according to picking areas in which the items are located. One picking vehicle corresponds to several picking sub-tasks. The picking management device allocates an automated guided vehicle (AGV) for a picking sub-task, causing the AGV to move the picking vehicle to a picking area corresponding to the picking sub-task. The picking management device may send task information of the picking sub-task to a picking device corresponding to the picking area. The picking device executes the picking sub-task according to the task information, so as to pick an item and place the item in the picking vehicle, thereby implementing the automation of an item picking process.

Abstract: An antenna module and a mobile terminal are provided. The mobile terminal has a metal frame and a system grounding spaced apart from the metal frame. The antenna module has a radiating body formed in the metal frame and a parasitic element coupled to the radiating body. The radiating body is configured for generating a main harmonic, and the parasitic element is configured for generating a parasitic harmonic. The antenna module further has a first tuning circuit connected in series between the radiating body and the system grounding, and a second tuning circuit connected in series between the parasitic element and the system grounding. The antenna system has at least four operation modes. The antenna system of the present invention may cover the LTE low, medium and high frequencies as a single antenna. A flexible and convenient method for tuning the antenna module is also provided.
