Description
[Technical Field]
[0001] The present invention relates to magnetoelectric dipole antennas and antenna arrays, and more particularly to magnetoelectric dipole antennas and antenna arrays used to receive circularly polarized electromagnetic waves. [Background technology]
[0002] Patent Document 1 discloses a single-layer magnetoelectric dipole element antenna array with four feed ports. This antenna array has four magnetoelectric dipole elements arranged in a 2×2 matrix. Each magnetoelectric dipole element includes a substrate, four rectangular dipole elements arranged in a 2×2 matrix on the upper surface of the substrate, a magnetoelectric dipole element arranged on the upper surface of the substrate so as to be surrounded by the four rectangular dipole elements, and a coaxial probe provided at an end of the magnetoelectric dipole element and inserted downward into the substrate. In the single-layer magnetoelectric dipole element antenna array, any two adjacent magnetoelectric dipole elements are connected by a microstrip line. The end of each magnetoelectric dipole element where the coaxial probe is provided serves as the feed port of the magnetoelectric dipole element. By adjusting the phase of the input electromagnetic wave signal received at different feed ports, the single-layer magnetoelectric dipole element antenna array can be freely switched between two functions: dual polarization and circular polarization, and achieves an axial ratio of circular polarization of less than 0.2 dB.
