Description
Summary:A compact CPW fed antenna is designed for the dual band operation. Here electromagnetic band gap structures of rectangle-shaped lattices are placed for the harmonic suppression. We observed that EBG structures are not only exhibiting the band stop characteristics, but also help to magnify the proposed antenna bandwidth. The rectangular lattice like EBG's have a frequency band gap and high surface impedance characteristics, which generally represent as in-phase reflection band. We succeeded in integrating the rectangular lattice EBG's in compact slot antenna with a CPW feeding line, to decrease the surface wave losses and bandwidth enhancement. The complete antenna analysis with radiation characteristics are presented in the current study.
