Embodiment 1

[0027] Please refer to figure 1 , this embodiment provides a desktop distribution device, including a housing 10 , a reconfigurable antenna array 20 , a switch circuit 30 , an antenna array processor 40 and a communication circuit 50 .

[0028] One side of the casing 10 is an issuing panel for placing devices to be issued.

[0029] The reconfigurable antenna array 20 is arranged in the casing 10 and includes a plurality of antenna units. In this embodiment, the reconfigurable antenna array 20 includes a plurality of electrically large-sized monopole (monopole) antennas and a plurality of electrically large-sized PIFA (Planar Inverted-F antenna, planar inverted-F antenna) antennas, and the number of monopole antennas and PIFA antennas equal, for example, the number is n (n is an integer greater than 1). Such as figure 1 As shown, 201 is the first monopole antenna, 202 is the nth monopole antenna, 203 is the first PIFA antenna, and 204 is the nth PIFA antenna. In other embod...

Embodiment 2

[0050] Please refer to Figure 5 , based on the desktop distribution device provided in the first embodiment above, this embodiment provides a corresponding method for controlling a reconfigurable antenna array of a desktop distribution device, including the following steps:

[0051] Step 1.1: The Antenna Array Processor reads the reconstruction pattern table.

[0052] Step 1.2: The antenna array processor selects a reconfiguration mode according to the sequence in the reconfiguration mode table, and controls the switch circuit to work in the selected reconfiguration mode. Each different reconstruction mode enables different antenna units to be in the open state. Preferably, multiple antenna units are in the open state in any reconstruction mode, so that the coupling of near-field energy can be used to expand signal coverage and improve compatibility. sex.

[0053] Step 1.3: The switch circuit controls the reconfigurable antenna array according to the selected reconfiguratio...

Abstract

The invention relates to a desktop issue device and a reconfigurable antenna array control method thereof. The desktop issue device is additionally provided with a switching circuit and an antenna array processor. In the communication process, the switching circuit is controlled to operate in one reconfiguration mode of a plurality of configuration modes through the antenna array processor, the switching circuit controls antenna units in a reconfigurable antenna array to be on or off according to the reconfiguration mode, and a communication circuit controls the antenna array processor to keep or switch the reconfiguration mode of the switching circuit according to signal receiving conditions of the reconfigurable antenna array in the current reconfiguration mode, thereby acquiring a reconfiguration mode satisfying communication requirements of the current device to be issued. Therefore, the desktop issue device can automatically select a reconfiguration mode with good communication effects to adapt to different devices to be issued, so that a problem of poor compatibility of the desktop issue device for different models of devices to be issued is solved.

Description

technical field [0001] The present application relates to the technical field of reconfigurable antenna arrays, in particular to a desktop distribution device and a control method for reconfigurable antenna arrays thereof. Background technique [0002] According to the national standard, the communication distance range of the antenna used by the 5.8GHz DSRC (Dedicated Short Range Communications, dedicated short-range communication technology) desktop distribution equipment is 1 to 20 cm. This area covers the reactive near-field and radiating near-field of the antenna. In this area, the electromagnetic field distribution area is irregular, coupled with the reflection and near-field coupling of the issuing object, making the electromagnetic environment more complicated. [0003] Take the desktop distribution equipment for on-board unit (OBU) distribution as an example, in actual use, the wake-up sensitivity, antenna pattern, antenna gain, dynamic range, and other indicators o...
