There are many uses for this metamaterial antenna such as broad band radars, 5G and automotive applications. With many works of wideband antenna are already available, this work presents a low cost super wide band combined with circular polarization, size compactness and high gain. Super wideband (SWB) is obtained by appropriately etching the patch and inserting a stub into the feed line. To increase the functional bandwidth, that covers 2.69GHz to 22.9GHz frequency range, rectangular slots and the electromagnetic bandgap(EBG) have been included to the ground surface in the interim. A 73% size decrease is achieved using performing partial grinding in addition to step feeding. Unlike traditional approach of employing complex feeding, etching multiple slots across multiple layers, additional elements for realizing circular polarization (CP) with large axial ratio (AR) bandwidth, a simple straightforward approach of using left-handed metamaterial (LHM) underneath the patch introduces circular polarization with wide 3dB axial ratio (AR) bandwidth ranging from 2.78GHz to 21.85GHz. The backing of patch by LHM reverses the radiation in forward direction which greatly enhanced the gain to 5.28dBi which is specific to the designed antenna. The suggested antenna has equipped with reconfigurable filters for tuning to one of three bands of interest whose center frequencies residing at 2.69GHz, 10.5GHz and 18.2GHz respectively across the super wide band that firmly reduces the undesired crosstalk. The vertical slit in the step feed of the suggested antenna enhances impedance matching across a broad operating band.
