A design for a printed inverted-F antenna (IFA) miniaturised by loading a ceramic chip coupler and to be used in Bluetooth applications is presented. The chip coupler is composed of printed meander lines on the surfaces of the ceramic (ɛr=21) chip. The proposed printed IFA with the chip coupler reduces the size of the general type printed IFA by up to 68.3%. The antenna has 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.
