초록

This letter compares two types of antennas for Bluetooth applications in mobile handsets; in the presence and absence of a human head. A Planar Inverted F Antenna (PIFA) and a three dimensional loop-type antenna were designed to fully cover Bluetooth services. The antennas are designed on a Frame Retardant Type 4 (FR-4) substrate (epsilon(=)4.4, tan delta=0.02) with the size of 140 mm X 45 mm printed circuit board (PCB) with 1 mm thickness.
