The invention aims to provide a double-layer single-feed circular polarization micro-strip patch array antenna based on the LTCC technology. The double-layer single-feed circular polarization micro-strip patch array antenna comprises an upper LTCC substrate, a lower LTCC substrate, a feed network, an upper radiation metal patch antenna array, a lower radiation metal patch antenna array, a metal probe, a feed port and a grounded metal layer, wherein the lower radiation metal patch antenna array and the feed network are arranged on the upper surface of the lower LTCC substrate, and the upper radiation metal patch antenna array is located on the upper surface of the upper LTCC substrate; the upper radiation metal patch antenna array and the lower radiation metal patch antenna array have the same shape and size, each antenna array is composed of four sub-arrays, each sub-array is composed of four radiation metal patches, each radiation metal patch is in a chamfered square shape, and rectangular gaps are formed in a set of opposite edges of each radiation metal patch. According to the double-layer single-feed circular polarization micro-strip patch array antenna, better consideration is given to performance requirements for the low profile, circular polarization and high gain of the micro-strip patch array antenna, and meanwhile the frequency band width of the antenna is increased greatly.
