Dual-Band 8x8 Adaptive Array Antenna for 3.5/5 GHz

Abstract

This paper gives result analysis for the adaptive antenna array is expected to meet data rate
requirement for 4G communication for Direct Sequence CDMA (DS-CDMA) antenna
application.In this paper 4G smart planner dual band phase array suitable Long Term
Evolution (LTE) at 3.5 GHz for fourth generation (4G)and also Wireless Local Area
Network(WLAN) at 5GHz system isdeveloped. The proposed planar array antenna is build
using micro strip U slotted patch antenna element. Separate feeding techniques are used for
every element of the smart planar array antenna and elevation direction at Sixty degree
phase shift absent of any grating lobes. At Sixty degree phase shift, the gain is to be 22.62dB
without changing in the mutual coupling. In this single element and linear sub arrays with
1x2 and 1x4 dimension of this element are designed.
