Abstract

The making of a Wang shape neutralization line is proposed in this article. A micro strip fed dual-band polarized antenna having two slits cut on left and right side of the patch is inserted to achieve neutralization between the two patches. The proposed structure has a dimension of 60 mm × 40 mm patches, optimization procedure of 0.09 λ0 is chosen to reduce the mutual coupling and to maintain the spacing between the two radiators. For impedance matching a microstrip feed line to a wang shape neutralization line antenna is excited by a 50 Ω to generate wider operating dual-bands. By congruously embedding small rectangular slots in the patch, the antenna unveils dual-band linear polarization. The dual-band proposed antenna mechanism, surface current distribution, parametric study; step by step antenna design is discussed here. This antenna is suited for WiMAX, 2.6 GHz and C-band, 6.1 GHz applications.
