Optimizing C-Band Antenna Performance Through Integration with Frequency Selective Surfaces: Design and HFSS Analysis
摘要
This research focuses on the design and optimization of antennas tailored for C-band frequency applications, spanning the microwave range of 4GHz to 8GHz. Two distinct antennas are meticulously crafted to cater to specific advantages within this frequency band: one emphasizes superior bandwidth, while the other prioritizes enhanced return loss and minimized Voltage Standing Wave Ratio (VSWR) values. The integration of Frequency-Selective Surfaces (FSS) is employed to further enhance the performance parameters of these antennas. The entire design process, encompassing conceptualization, modeling, and simulation, is executed using the HFSS software—an advanced platform renowned for its capabilities in simulating and analyzing complex electromagnetic interactions. The antenna’s construction employs an FR4 epoxy substrate, featuring a dielectric constant of 4.4 and a substrate thickness measuring 1.6mm. Similarly, the FSS unit cell utilizes a substrate thickness of 1.6mm. The antenna is meticulously engineered to operate within the microwave C-band, spanning frequencies from 4GHz to 8GHz. Its primary design emphasis centers on highlighting the impact of Frequency-Selective Surfaces (FSS) on antenna performance.
