Nokia's device is somewhat less ambitious and is made possible thanks to a wide-bandantenna and two very simple circuits.
诺基亚的这款手机倒没那种雄心豪情，它是采用宽带天线及两个非常简单的电路来达到目的的。

The small-size wide-bandantenna (103) further includes a stub conductor (17) as an impedance matching unit for matching the impedance between the radiation element and the power supply means.
The elliptical planar monopole antenna has the advantages of simple structure, wideband and relatively simple feed, so it can meet the demands of wide-band and high-gain at the same time.
