This article presents a novel compact ultra-wideband (UWB) planar monopole antenna printed on an FR4 substrate. The antenna consists of a pentagonal radiating element and incorporates loading metamaterial complementary split ring resonator (CSRR) on the ground plane to optimize impedance matching for UWB operation. The overall dimensions of the designed antenna are 17.75 × 20 mm2. The proposed compact UWB antenna exhibits an operating bandwidth from 3.01 to 12.41 GHz with a −10 dB return loss and a fractional bandwidth (FBW) of approximately 123%. Additionally, the proposed antenna exhibits a stable radiation pattern with a peak gain of 6.3 dB and a peak radiation efficiency of 98.3%. To validate the simulation results, a prototype has been fabricated and measured, which shows good coherence with the simulation results. In addition, the proposed design is compared with leading antennas for similar applications to demonstrate the suitability of its concept. Moreover, an equivalent circuit model of the CSRR metamaterial cell is developed and validated using ADS software.
