Abstract
In this paper, the design, Optimization and simulation of a dual-band coaxial-fed 2x2 rectangular U-Slot microstrippatch antenna array for wireless sensor network applications is presented. It operates on 2.1GHz and 3.5GHz bands. A MIMO antenna is proposed for high speed WSNs based communication standards that operates in 1-5GHz frequency range. Antenna design and simulation is performed in Agilent ADS Momentum using Rogers TMM3 substrate (epsilon r =3.27 and h=6.35mm). The maximum achieved gain for2 x 2 U-slot rectangular patch antenna array is 11dBi. Substrate losses are also taken into account during simulation process. Simple design procedure and optimization techniques are also discussed to design a single element dual-band patch antenna. The proposed array may be used as a template to form larger arrays.
