Improving handset antenna performance by wideband matching optimization

Matching circuits have not been paid much attention when studying antennas, although they have a significant effect on the performance of the designed antenna. This paper presents an easily adopted procedure to design wideband matching circuits for an arbitrary, frequency-dependent, real-life load impedance through optimization using a commercial circuit simulator. Several CCE antenna examples demonstrate the capability of the proposed method and emphasize the importance of the matching circuit design.
