This article presents the design of an ultrawideband antenna with quadruple band notch characteristic using negative permittivity unit cells. Quad notched band characteristics are achieved at desired frequency bands by etching four complementary split ring resonators on the modified rectangular patch, which is then validated by experimental results. The antenna has impedance bandwidth for voltage standing wave ratio (VSWR) <2 from 2.85 to 11.52 GHz, with a notched band characteristic in the sub‐6 GHz 5G (3.39‐3.82 GHz), IEEE 802.11a WLAN at 5.2 GHz (5.13‐5.40 GHz), IEEE 802.11a WLAN at 5.8 GHz (5.71‐5.91 GHz), and ITU 8 GHz (7.5‐8.61 GHz) signal bands. Furthermore, the antenna has a compact overall size of 40 × 30 × 0.81 mm 3 with a stable radiation patterns.
