The capability of complementary capacitively loaded loop (CCLL) metamaterial (MTM) to miniaturise printed slot antenna is examined. This study presents a planar compact antenna with the overall size of 15 × 9 mm2 for handheld/portable applications. The antenna is comprised of four sections: coupled-fed, a parasitic line, a CCLL-MTM, and a slot. It is shown that CCLL-MTM exhibits a magnetic behaviour through the frequency band of 2820–3200 MHz, which causes antenna miniaturisation while simultaneously helps radiation enhancement. To validate the simulation results, a prototype of the antenna is fabricated and tested. Good agreement between the simulation and measurement results is obtained.
