Abstract
AbstractNear‐field radiation characteristics of an internal cellular handset antenna with a curved metal pattern are studied.The antenna's metal pattern comprises a simple strip monopole for the GSM1800/1900 operation. The strip monopole is smoothly curved to avoid right‐angle or abrupt bendings such that smooth variations of the excited surface currents thereon can be obtained. In this case, it is expected that the antenna's near‐field radiation can be decreased. When compared with a corresponding monopole antenna with one or more right‐angle bendings, the obtained results show that the proposed antenna can have lower specific absorption rate values by at least 1.0 dB, which is mainly owing to the decreased near‐field radiation. Detailed results are presented and discussed. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:1927–1932, 2012; View this article online at wileyonlinelibrary.com. DOI 10.1002/mop.26958
