In the presented work, a simple printed compact dual Sinc‐shaped monopole antenna suitable for dual‐band operation is proposed for portable wireless devices. The proposed antenna consists of dual Sinc configuration: one a Sinc‐shaped radiating strip and another Sinc‐shaped sleeve in the ground plane. The antenna operates at dual frequency bands, 2245–2635 MHz, and 4589–5112 MHz, showing 10 dB fractional impedance bandwidths of 16 and 10.8%, respectively. A simple approximate formula for the first two resonant frequencies is also presented. Finally, A prototype model is developed for the proposed configuration and the simulated results are validated experimentally. The antenna is found to be suitable for long term evolution handheld devices, WiMAX, WLAN, and public safety land mobile. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2883–2888, 2013
