摘要

提出了一种毫米波天线增益增强技术。讨论了磁各向异性和电磁传播的理论和机理。各向异性磁介质(AMM)为不同的横向电(TE)波提供了路径长度补偿,使其在没有相位积累的情况下传播。研究了各向异性磁介质对微带贴片天线增益增强的影响。当放置在散热器上方时,AMM提供了约5.3dB的增益增强,从而在28GHz时实现85%的孔径效率。

Anisotropic Magnetic Media for Antenna Gain Enhancement
This paper presents a gain enhancement technique for millimeter wave antennas. The theory and mechanism of magnetic anisotropy and electromagnetic propagation are discussed. The anisotropic magnetic media (AMM) provides path length compensation for different transverse electric (TE) waves to have propagation without any phase accumulation. The effect of anisotropic magnetic media is studied for antenna gain enhancement using a microstrip patch antenna. The AMM provides a gain enhancement of about 5.3dB when placed above the radiator, resulting in an aperture efficiency of 85% at 28GHz.
