A novel dual cross-shaped shorted-slots loaded patch antenna is proposed and analyzed in this article. The radiated patch antenna was chiseled two cross-slots, there are shorted-lines to be set at the middle- and cross-points of slots, which is designed to be operated at dual-ISM(Industrial, Scientific, and Medical) band (2.4 and 5.8 GHz bands). A prototype of the proposed antenna with 63 mm in length, 7.6 mm in height and 72 mm in width is fabricated and experimentally investigated. The experimental results indicate that the VSWR ≤ 2.5 bandwidths achieved were 13.3% and 15.9% at 2.45 GHz and 5.5 GHz, respectively. There is good agreement between the simulated and measured results.
