Dual Polarized Patch Antenna Design for LTE and WLAN Application

This paper describes design of microstrip patch antenna validating dual band and dual polarization behavior of radiations for the multi-band communication applications. Designed antenna has been simulated for 2.40 GHz of resonance frequency having geometrical extents of 38 mm X 49 mm providing dual band behavior comprising Long Term Evolution (LTE) 4-G band (2.40 GHz – 2.49 GHz) and WLAN band (5. 35 GHz - 5. 85 GHz). Inserting slots on the radiating corners of patch width has been carried to accomplish the circular polarized (CP) by utilizing the identical geometry. Among the two bands, LTE bad is operated in linear polarization where, WLAN band is committed to operate in circularly polarized feature with ≤ 3dB axial ratio, giving orthogonal E-field circulations at WLAN band. Single feeding mechanism provides CP operations and the designed geometry accomplishes the straightforwardness about simplicity in the radiating antenna structure.
