In this article, a self complementary frequency independent triple band Sinuous Antenna Array (SAA) is designed for wireless applications such as Mobile Satellite Service (MSS), Global Positioning System (GPS) and Global System for Mobile communications (GSM). Four Sinuous elements are connected to the nearest one in such a way to form an array structure. A prototype of a Sinuous Antenna Array (SAA) is embedded into a flame retardant-4 (FR-4) dielectric material. The performance of the proposed antenna array has been analyzed by using Ansys High Frequency Structure Simulator (HFSS). The suggested antenna is fabricated and tested. From the measured results, the proposed antenna array can be operated at the frequencies of 1.54 GHz for GPS, 1.76 GHz for GSM and 2 GHz for MSS with a reflection coefficient of below −10 dB. It has good reflection coefficient characteristics, Voltage Standing Wave Ratio, impedance bandwidth, axial ratio, surface current distribution and radiation characteristics.
