Design of hexa-band planar inverted-F antenna using hybrid BSO-NM algorithm for mobile phone communications
This article presents a new design of multiband planar inverted-F antenna with slotted ground plane and S-etched slot on the radiation patch. The proposed antenna is optimized using an efficient global hybrid optimization method combining bacterial swarm optimization and Nelder-Mead (BSO-NM) algorithm to cover a very important six service bands including GSM900, GPS1575, DCS1800, PCS1900, ISM2450, and 4G5000 MHz with enhanced bandwidths. The BSO-NM algorithm in Matlab code is linked to the CST Microwave studio software to simulate the antenna. To validate the results, the antenna is analyzed using the finite difference time domain (FDTD) method. A good agreement is achieved between the results of EM simulation and that produced from the FDTD method.  2012 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2013.
