Penta-band internal antenna for mobile handset

Personal mobile handsets are required to operate at multiple frequency band for many services. In this paper, penta-band; DCS(1710 - 1880 MHz), PCS(1850 - 1990 MHz), WCDMA(1920 - 2170 MHz), Wibro(2300 - 2390 MHz), Bluetooth(2400 - 2480 MHz) internal antenna is proposed. It consists of three radiation elements. One meander line antenna and a monopole antenna which are located at bottom layer are direct fed directly using SMA connector. Another parasitic meander line antenna which is located at top layer is fed using gap coupling structure. The measured impedance bandwidth (VSWR 2:1) of proposed antenna is 260 MHz(1730 - 1990 MHz) and 590 MHz(2110 - 2700 MHz). It can be operated five frequency bands services. Measured maximum gains of antenna 1, antenna 2 and antenna 3 are 3.43 dBi, 0.19 dBi and 1.03 dBi, respectively. The proposed antenna is made on a FR4 dielectric substrate (relative dielectric constant = 4.4, thickness = 0.8 mm) and it is cost effective.
