Novel Bludgeon-Shaped Microstrip Antenna with DGS for UWB Applications with Notch Band Characteristics

In this work, a novel bludgeon-shaped microstrip patch antenna with defected ground structure (DGS) is recommended for UltraWide Band (UWB) i.e., (3.1–10.6 GHz) applications with band notch characteristics. The encouraged antenna is simulated and fabricated using RT DURIOD 5880 substrate with epsilon value of 2.2 having the scale of 60 × 60 × 1.6 mm3. The circular-shaped patch is chosen with radius of 14 mm and 50 Ω microstrip line feeding technique is used for the simplicity of the design. The circular slots and circular-shaped patch are delivered to improve the radiation traits and overall performance of the recommended antenna. To acquire the UWB frequency of operation, rectangular defected ground structure (RDGS) is implemented in the ground plane. Further, three rectangular slots of different dimensions are etched to accomplish the band notch configuration. The recommended antenna is simulated using 3D electromagnetic simulation tool CST MICROWAVE STUDIO Version16. The evolved antenna is tested using MS46122B 20 GHz vector network analyzer. The effectiveness of the antenna is proven the usage of the specifications like return loss (S11), VSWR, and simulated radiation patterns.
