Abstract

The invention discloses a microstrip array antenna with a harmonic suppression function. The microstrip array antenna comprises a dielectric substrate and a microstrip antenna array printed on the surface of the dielectric substrate. According to the microstrip array antenna, feeding is carried out through microstrip lines loaded with compact microstrip resonant units, so that the harmonic radiation loss of the antenna can be avoided; and a miniaturization high-isolation power divider is adopted, so that the microstrip array antenna can be small in size and compact in structure. The microstrip array antenna of the invention can be used to a microwave power transmission system. The microstrip array antenna has the advantages of applicability to the plane miniaturization of a system, small size, easiness in integration and high efficiency.

Description

technical field [0001] The invention belongs to the field of antenna design, in particular to a microstrip array antenna with harmonic suppression function. Background technique [0002] With the increasing shortage of non-renewable resources such as oil and coal and the rapid development of semiconductor electronic technology, Microwave Power Transmission (MPT) technology has received more and more attention and research, and microwave rectenna technology is the most critical technology one. [0003] The specific working principle of the rectenna is to receive the microwave energy in the space through the receiving antenna, and convert the energy into DC through the rectifying circuit, so the design of the receiving antenna has a great influence on the performance of the rectenna. At present, there are mainly monopole, planar printed dipole and microstrip antennas in the form of receiving antennas. Microstrip antennas are widely used in the design of receiving antennas in ...
