The invention provides a three-dimensional seven-band mobile phone antenna, aiming to provide a smart phone antenna that is miniaturized and compatible with multiple communication frequency bands of 2G / 3G / 4G. The present invention includes a first substrate, a second substrate, a first metal sheet group, a second metal sheet group, and a third metal sheet group; the first metal sheet group is directly fed, and can excite high-order resonant modes for covering high frequency band, the second metal sheet group and the third metal sheet group together form a parasitic short circuit band, which is used to expand the bandwidth to cover the low frequency band. The invention adopts a three-dimensional structure, makes full use of the space, and reduces the area occupied by the antenna on the main circuit board of the mobile phone, which is only 30mm*11mm, and has a large bandwidth, covering multiple frequency bands of 2G / 3G / 4G. , the present invention does not contain any lumped components and special substrate materials, is light in weight and high in efficiency, and is suitable for current smart phones.
Description
technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a three-dimensional seven-band mobile phone antenna. Background technique [0002] In the communication industry, the mobile phone market is facing the fiercest competition, and the mobile phone antenna design is an important part of product design, which is directly related to whether mobile phone manufacturers can enter the high-end market. In today's situation where multiple communication standards coexist, mobile phones are required to implement more and more functions, all of which require the antenna to be designed with a larger bandwidth to cover all commonly used frequency bands. Smartphone antennas generally integrate 2G, 3G and 4G systems together to cover as many frequency bands as possible. Broadband antenna design has always been the focus of smartphones, especially for low-band (GSM850 / 900) coverage, which is even more challenging. With the advent of ...
