Computational Devices for Intelligent Vehicular Systems and Smart Networking

Abstract

A novel microstrip bandpass filter with split ring resonator (SRR) defected ground structure (DGS) patch antenna for computational applications is proposed in this article. This filter and antenna design can collaboratively work as filtenna for improved performance by minimizing the total power consumption in the system. The investigation is carried out on width of the slit opening of SRR slot (W) and rotation of the inner square-shaped ring structure in clockwise direction. The proposed filtenna is designed to provide a tunable frequency operation. Simulation is performed on high-frequency structural simulator (HFSS) which demonstrates good output response making filtenna design suitable for intelligent vehicular communication and wireless local area network (WLAN) applications. The proposed filtenna is compact in size, has low insertion loss, exhibits high selectivity, and demonstrates excellent out-of-band performance.
