Abstract :
In this paper a printed inverted-F antenna (IFA) is miniaturized by loading a ceramic chip coupler for bluetooth applications. The chip coupler is composed of printed meander lines on surfaces of the ceramic (εr=21) chip. The proposed printed IFA with the chip coupler is reduced up to 64.9 % compared with a general printed IFA. The size of antenna is a volume of 35.1 mm3. The -10 dB bandwidth was measured as 90 MHz (3.68 %). The measured radiation pattern shows omnidirectional patterns in the yz plane and xy plane.
