Design of Sierpinski Knopp Inspired Fractal Antenna for Public Safety Applications

摘要

This article presents a design of compact Sierpinski Knopp Fractal (SKF) antenna for public safety applications. The proposed antenna consists of Sierpinski Knopp space-filling curve inspired radiating element, partial ground plane, and microstrip feed. The physical dimension of the antenna is 35 x 35 x 1.6 mm(3) (0.58 lambda x 0.58 lambda x 0.03 lambda at the operating frequency of 4979 MHz). The proposed antenna has been manufactured and examined by using the Agilent Vector Network Analyzer (VNA) under anechoic chamber. The experimental results reveal that the antenna exhibits a reflection coefficient of - 17.5 dB at 4979 MHz with an impedance bandwidth of 180 MHz. The measured results of the designed SKF antenna are offered good accord with that of simulated results. It is suitable for Public Protection and Disaster Relief (PPDR) communication.
