A new multiband, multimode printed antenna inspired by metamaterial transmission-line (TL) structures is introduced. The design consists of periodically added left-handed (LH) series capacitances and shunt inductances in the first-seen right-handed (RH) coupled-fed loop antenna to increase multiple resonant modes. All these LH and RH elements are built on the single-layer substrate in a coplanar structure of size 35 mm × 5.5 mm merely. The compact nature makes the design well suited for applications on laptop computers where internal space is always limited. The multiband operation, including the metamaterial TL and RH loop modes, covers the 5G new radio (NR) bands 77/78 and the Wi-Fi 7 bands in the 2.4/5/6 GHz wireless local area network (WLAN) in tandem. The measured total efficiency outperforms 46%, 77%, and 70% in the respective 2.4, 5/6 GHz, and NR 77/78 bands. The data from both computer simulations and experiments also support the functionality of this work.
