The invention provides a soft surface structure-based patch array antenna, and aims at achieving miniaturization while keeping high gain of the patch array antenna. The soft surface structure-based patch array antenna comprises five dielectric plates which are stacked from top to bottom, wherein a first composite metal band is printed on the first dielectric plate; a second composite metal band and m*n upper radiating elements are printed on the second dielectric plate and each upper radiating element comprises 2*2 upper radiation patches; m*n first plated through holes are arranged in the third dielectric plate, a third composite metal band and m*n lower radiating elements are printed on the upper surface of the third dielectric plate, each lower radiating element comprises 2*2 lower radiation patches and a main radiation patch, an internal grounding plate is printed on the lower surface of the third dielectric plate and m*n feed via holes are etched in each internal grounding plate;the first composite metal band, the second composite metal band and the third composite metal band form a soft surface structure; m*n second plated through holes are arranged in the fourth dielectricplate; and an external grounding plate is printed on the lower surface of the fifth dielectric plate and a feed network is printed on the upper surface of the fifth dielectric plate.
Description
technical field [0001] The invention belongs to the technical field of antennas, and relates to a patch array antenna, in particular to a patch array antenna based on a soft surface structure, which can be used in wireless communication fields such as vehicle-mounted devices. Background technique [0002] With the rapid development of modern wireless communication systems in the world, the performance requirements of antennas are getting higher and higher, such as strong directivity, high gain, narrow beam, small size, etc. A single antenna generally cannot meet the requirements, so it is necessary to build an array antenna. Array antennas are a common form of antenna found in modern radar and communication systems. In array antenna design, gain and size are important performance indicators. The larger the antenna size, the higher the antenna gain, but the larger the space required to install the antenna. Therefore, how to reduce the size of the array antenna while mainta...
