Investigation of Hexagonal Antenna with Ring Resonators

Ultra wide band (UWB) system will generally provide the advantages like wide bandwidth, minimizing the structure, low power requirements, and high efficiency. The bandwidth of a proposed hexagonal antenna has been improved with hybrid slots, correlate single split ring resonators (CSSRR), and partial ground. This printed monopole hexagonal loaded with CSRR are designed on flame retardant (FR) epoxy glass material with dielectric constant 4.4, where its overall size is 21mm × 30mm. The operating bandwidth of proposed antenna is 3.25GHz - 16.37GHz. The proposed antenna will be well-suited for wireless technologies like WiMax, WiFi, WLAN and IoT applications, where it is proved with simulated electrical, far field report, and surface current distribution.
