This paper presents the design and realization of a compact dual-band antenna for industrial scientific and medical (ISM) band applications. The compact geometry of the antenna is achieved by combining two miniaturization techniques like defected ground structure (DGS), and by using the truncated patch structure. The antenna is design on cheap FR4 to minimize the cost, while radiator geometry was kept simple to avoid unnecessary fabrication errors. The antenna is comprising of overall compact size of 18 × 18 × 1.6 mm3. Moreover, the dualband and stable omni-directional radiation pattern makes the presented antenna a potential candidate for modern day compact devices.
