In this article, a triple‐band metamaterial (MTM)‐inspired antenna has been designed and analyzed using finite difference time domain technique (FDTD). The proposed MTM consists of two L‐dumbbell‐shaped unit cells, feed, and partial ground plane. The proposed antenna shows triple‐band characteristics with impedance bandwidths of 10.6, 4.67, and 26.8% centered at 2.4, 3, and 5.7 GHz, respectively. The first two bands are working at zeroth‐order resonating mode and first‐order resonating mode while third is due to series slot and coupling between feed and ground plane. It offers compact nature with total antenna size of 30 × 30 × 1.6 mm 3 . The proposed triple‐band antenna has been designed and analyzed using FDTD code based on convolutional perfectly matched layer boundary conditions and HFSS as well. The prototype antenna has also been fabricated and tested experimentally to validate the simulation results. The proposed antenna exhibits good radiation characteristics throughout the working bands. © 2015 Wiley Periodicals, Inc. Int J RF and Microwave CAE 25:688–695, 2015.
