A NEW COMPACT MICROSTRIP ANTENNA FOR WSN APPLICATIONS

摘要

We propose a new dual-band microstrip antenna using compact quasi-fractal resonator with a ladder-shaped slot at a fundamental frequency around 2.45 GHz for Wireless Sensor Network (WSN) appliances. It was constructed using one layer of FR4 substrate with double via ports feeds to function as dual-band at 2.45 and 2.95 GHz respectively. This antenna has compact substrate size (31 mm x 31 mm) with feasible radiation performances and return loss responses, which can be jointly adopted in WSN and other applicable wireless systems such as Internat of Thing (IoT) and Wireless Local Area Network(WLAN).
