A compact frequency reconfigurable coplanar stripline (CPS)‐like metamaterial antenna for WLAN and GSM applications is proposed in this article. A unique CPS structure is used to exploit the properties of metamaterial and it is being inspired from an epsilon‐negative transmission line (ENG‐TL). The main objective of using this structure is to simplify the geometry and to achieve frequency reconfigurable operation. The proposed antenna of size 40 × 40 × 1.524 mm 3 with acceptable gain and radiation pattern will operate at two switching frequencies 1.8 GHz for GSM and 2.4 GHz for WLAN, respectively. Parametric analysis of the proposed antenna unit cell is performed using ADS in which by tuning the unit cell parameters WLAN band is achieved. To achieve the frequency reconfigurable property, RF PIN diode model is implemented on the antenna structure. Results of the prototype of antenna are compared with the simulated results. A close agreement is found between the measured and the simulated results. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:596–601, 2017
