SHAPE MEMORY ALLOY NITI ANTENNA WITH WIFI APPLICATION

In this paper, some of planar metal-plate antenna designs, which are made of Shape Memory Alloy NiTi, have been discussed. Shape memory materials, especially NiTi, can be an alternative to conventional metals in terms of its good characteristics of higher strength, corrosion resistance, ductility, high recoverable deformation, relatively high electrical conductivity, and biocompatibility. In this work the names of these antennas are called 'Circular NiTi Plate Antenna' and 'Flat NiTi Plate Antenna' which have been designed according to dual band 2.4 GHz and 5GHz Band. These antennas are fabricated from a one-piece equiatomic NiTi plate, which is Metal-plate, therefore they have better gain and radiation efficiency performance. The performance tests have been done in free space conditions and also in an oven which has metal housing effect. The antennas show stable gain and radiation patterns over the 2 GHz and 5 GHz Band in both free space conditions and metal environment.
