Abstract

A miniaturized printed integrated inverted-F antenna (PIIFA) is proposed which operates in the Bluetooth frequency band (2.4-2.485 GHz). The antenna is derived from a modified Hilbert geometry and can be easily fed using a 50 Ω printed transmission line. The antenna being an integral part of the printed circuit board (PCB) reduces the cost and complexity of manufacturing the whole unit. The antenna on a standard FR4 substrate (ε_r = 4.5) measures 9.25 mm by 4.125 mm and has a bandwidth of 3.5% within 2.5:1 VSWR. The peak gain is 1.2 dBi. An overall size reduction of 67% can be achieved compared to a conventional inverted-F antenna.
