Bandwidth Enhancement of Multiband Microstrip Patch antennas for C-Band Applications

CHANDRA BHUSHANA RAO, M. Ravi Kishore

Abstract


systems to Biomedical system, because of numerous attractive properties such as light weight, low production cost, low profile, reproducibility, reliability, conformability and integration with solid state devices. Scientists are considering the operative approaches for real utilization of bandwidth of microstrip patch antenna. This paper presents the Enhancement methods of Bandwidth in Multiband microstrip patch antennas used for multiple applications of C-band. The enhancement of Bandwidth in T-shaped Duel band and E-shaped Triple band is observed by introducing metallic thin slots in both patch and ground plane with specified dimensions. The edge feeding method is used to achieve better impedance matching and FR4epoxy having dielectric constant 4.4 with optimum values of substrate heights are used. The design, analysis and comparison is done with respect to different parameters like VSWR, Gain, Peak directivity, Return losses, Radiation efficiency, FBR etc,. These antennas are simulated using HFSS (High Frequency Structure Simulator) version 13.0 software.

Keywords:bandwidth, C-band, dual band, edge-fed, HFSS software 13.0, triple band, slotted ground.
