Özet

Low-profile antennas are desirable in personal communications due to attractive features such as low cost, light weight, conformability, and ease of integration. A major challenge in low-profile antenna design is the trade off between the (reduced) antenna profile and performance. This tradeoff can be ameliorated by loading the antennas with properly designed metamaterials. In this paper, we explore the use of a new anisotropic metamaterial as antenna substrate and examine its effect on the input impedance of two types of low-profile antennas. We have shown that height reduction can be achieved without significant change on the antenna input impedance. ©2010 IEEE.
