摘要：

This research proposal includes the design of a unique coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna prototype with dual notch band characteristics. The microstrip line fed antenna features a configuration of geometric slots, including a rectangle, a semi-circle slots, and a pentagonal stub, along with a microstrip feedline. The antenna measures 35.4 mm × 28.82 mm. Two notches are introduced at 5 to 5.8 GHz (14.8% bandwidth) and 7.2 to 7.8 GHz (8% bandwidth) by incorporating split ring resonators (SRRs) on the bottom surface. Aside from the dual stopbands for the WLAN band (5 to 5.8 GHz) and SHF satellite communication band (7.2 to 7.8 GHz), the designed antenna operates over an impedance bandwidth from 3 GHz to 11.2 GHz with voltage standing wave ratio (VSWR) below 2. The proposed antennas have been developed, prototyped, and successfully verified. Simulation data and measurement results are thoroughly examined and analyzed. To confirm the applicability of the antenna in pulsed communication systems, the correlation among the input signal of the transmission antenna with the output signal of the reception antenna in the time domain is estimated. This confirms that the antenna prototype is well suited for wireless communication applications in military radar systems, medical imaging, consumer electronics, and more. © 2024, Electromagnetics Academy.
