Abstract

In this article, a dual bow-tie slot antenna for 915/2450/5800 MHz triple band RFID applications is presented. The size of the proposed antenna is determined by the middle resonant frequency. The lower and upper operating frequencies are obtained by inserting metal strip pairs near the ends of the slotted dual bow-tie without increasing the overall antenna area. The hybrid approach involving Central Force Optimization and Nelder-Mead (CFO-NM) algorithm is considered to optimize the antenna dimensions. The CFO-NM algorithm program was implemented using MATLAB-software which linked to the CST Microwave studio software to simulate the antenna. In addition the optimized antenna is simulated by the Finite Difference Time Domain (FDTD) method to validate the results.
