Abstract :
Circular Spiral with twelve element corporateseries feed antenna array operates at the center frequency of 956MHz is designed and analyzed. Each of the single circular spiral inductor is connected after one another. The purpose of design the circular spiral corporate-series feed antenna array is to achieve high gain antenna and subsequently harvesting more RF energy. The quarter wave transformer method is used to design the corporate feed line with the same equal distributed power in each arm. The entire structure was investigated using numerical solver such as finite integration technique (FIT) method. With this setup, the results show that 19.8dB gain for antenna array can be achieved at frequency 956MHz. Therefore, the results obtained can be used as an alternative design solution for application in the UHF band in future. A good agreement between simulation and measurement results is successfully confirmed.
