Abstract

This paper presents a novel compact internal antenna with the modified planar inverted F antenna (PIFA) type and investigates the influence of the handset case and battery. The proposed antenna operates at KPCS (1750-1870 MHz), and Bluetooth (2400-2483.5 MHz) bands in a practical handset. The represented antenna can be easily installed in practical handsets with the small size. The bandwidth of the proposed antenna (VSWR < 2) shows 140 MHz in KPCS band and 90 MHz in Bluetooth. Numerical simulation and experiment results are performed considering the antenna and the telephone case and battery.
