Description

technical field [0001] The invention belongs to the technical field of microstrip antennas, in particular to a miniaturized multi-frequency antenna based on a ferrite substrate. Background technique [0002] Microstrip antennas are widely used in miniaturized wireless communication scenarios due to their low profile, small size, and easy processing. However, miniaturized microstrip antennas made of traditional dielectric substrates have been difficult to meet the requirements of increasingly highly integrated devices. space given. Magnetism and dielectricity are the two main physical properties used in the work of many electronic components. Nowadays, the research on the miniaturization of microwave devices mainly focuses on the innovation of device structure and advanced manufacturing and packaging technology. There are very few studies on the dielectric of high-frequency devices, and even less on materials such as ferrite that have both dielectric and magnetic properties....
