In this study, a probe fed E-shape fractal patch antenna (EFPA) for heptads' band LTE/WWAN (GSM850/900/1800/1900/UMTS/LTE2300/2500) operation is proposed. Various iterations of this fractal antenna are compared, and an optimized design is presented. Exploitation of E-shape fractal notion in antenna design makes the patch antenna flexible in terms of generating resonances and bandwidth as an iteration order of the fractal is increased. Several properties of the antenna such as impedance bandwidth, radiation patterns, radiation efficiency, electric current distributions on the patch, and gain have been demonstrated numerically and empirically in detail. Experimental results have authorized the design procedure and confirm the gratification of the requirements for multistandard mobile terminal applications.
