PIFA-monopole internal mobile phone antenna for GSM/DCS/PCS triple-band operations

摘要

A novel internal mobile phone antenna comprising a planar inverted-F antenna (PIFA) and a low-profile planar monopole, which are designed, respectively, for covering the DCS/PCS and GSM bands, is proposed in this paper. The PIFA and the planar monopole together occupy a compact volume of 6.8 × 7.0 × 34 mm{sup}3, and are suitable to be built-in within the housing of a mobile phone. In addition, both the PIFA and the planar monopole have simple structures, which makes the proposed antenna easy to design and implement with a relaxed fabrication tolerance. A prototype of the proposed antenna was constructed and experimentally studied.
