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 ... إقراء المزيد
