Abstract
A miniaturized multiband printed antenna designed for high dielectric ceramic filled Bio plastic composite material is presented. The multiband antenna formed by Y shaped patch with a partial ground plane. The performance benchmarks of the proposed antenna have been experimentally verified by fabricating a printed prototype. The experimental results confirm that the proposed antenna achieves - 10 dB impedance bandwidth of 10.07% (1.79-1.98 GHz) at lower band and 8.83% (2.38-2.6 GHz) at the upper band, respectively. The antenna configuration and parametric study have been carried out with the help of the commercially available EM simulator and a good harmony is apparent between experimental and numerical results. Moreover, the antenna has a simple planar structure of a small area of only 38 mm x 40 mm. The proposed antenna can operate PCS1900 and WLAN bands. Good radiation characteristics, gain and radiation efficiency are obtained over these operating bands.
