Abstract

A small size PIFA using intergidital coupling feed for internal mobile phone antenna application has been proposed and studied. The proposed PIFA is easily printed on the no-ground portion of the system circuit board of the mobile phone at lowcost and occupies a very small area of 400 mm2 only, owing to the successful excitation of the mode as the fundamental resonant mode. The interdigital coupling feed greatly decreases the very large input impedance seen at the λ/4 mode for the traditional PIFA. The PIFAgenerates two wide operating bands at about 900 and 2100 MHz to cover GSM850/900 and GSM1800/1900/UMTS/WLAN operations, respectively. Good impedance matching of the two wide operating bands is achieved by using the interdigital coupling feed in the proposed PIFA..
