Embodiment Construction
[0053] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0054] With the rapid improvement of communication technology, the Internet of Everything has entered people's daily life. At the same time, some new needs, such as indoor positioning, are driven by the upgrading of technology. It has been found that the Internet of Everything brings about a huge increase in the demand for data and information throughput of communication systems. In response to this demand, multiple-input multiple-output (MIMO) technology is increasingly used in various scenarios, such as outdoor wireless communication, Wi-Fi data transmission, etc. The MIMO technology ...

The invention discloses a low-profile antenna structure and an antenna codebook generation method. The structure comprises a dielectric substrate, the dielectric substrate is provided with a radiation patch, one end, close to the dielectric substrate, of the radiation patch is provided with a grounding pin, the dielectric substrate is provided with an insertion hole for the grounding pin to pass through, the radiation patch is provided with a gap, and equivalent series capacitors are equivalently introduced into the gaps. Based on the antenna structure, the invention also provides a codebook generation method. The method comprises the following steps of arranging the antenna units according to a preset arrangement rule to obtain an antenna array body, determining the weight of the antenna unit in each direction of the antenna array body through oversampling, and obtaining a weight codebook of the antenna unit in each direction of the antenna array body, assigning each antenna unit in the antenna array according to the weight codebook to determine a codebook, and determining the antenna codebook according to the codebook and a preset index number. The utilization efficiency of the antenna can be improved by exciting the omnidirectional radiation mode of the antenna.
Description
technical field [0001] The invention relates to the field of antennas, in particular to a low-profile antenna structure and an antenna codebook generation method. Background technique [0002] In the 5G era, beamforming technology based on Massive-MIMO array antennas has been widely used, but it was mainly aimed at outdoor wireless mobile communication scenarios before. In recent years, the antenna system of indoor communication equipment has become more and more complicated. More and more devices support multi-antenna MIMO. For example, you can see that many Wi-Fi routers are equipped with 4 antennas and support beamforming. Wi-Fi6 and super All Wi-Fi protocols support MIMO. However, since most indoor devices use antennas like dipoles, it is impossible to place more than two groups in the vertical direction due to their high profile, which limits the beamforming capabilities of these devices in the vertical direction, thus As a result, the utilization efficiency of the an...
