The rapid growth of mobile communications since the introduction of GSM has challenged the industry for designing terminals of reduced size, cost and power consumption. The efficiency and size trade-offs of the antenna on such terminals become an important issue. On the other hand, multi-band operation covering the existing GSM900/DCS1800 and the future UMTS bands is another significant subject of investigation in the mobile phone industry. In this paper, different methods for tuning the planar inverted-F antenna (PIFA) are discussed, in particular with regard to the positioning of the short pins and the introduction of tuning capacitors. A reduced size dual band fine tuned PIFA for the GSM900/DCS1800 bands is introduced and its performance demonstrated. Finally, a technique employing reversed biased varactors for electronically tuning the PIFA is presented.
