Design of Dual Notch Band Antenna with Rejected Filter with Defected Slot for WLAN and Satellite Applications
This paper presents a defected microstrip structure to realize a band rejected performance. Two different U shaped slots with variable lengths are introduced on the signal line which simply shows L-C resonance properties. Due to such behavior, two notches are found about 5.8 GHz (the upper WLAN band 5.15–5.85 GHz) and 8.2 GHz (X-band satellite communication). The entire design is developed on a RT-Duroid substrate of relative permittivity 2.2 and a height of 0.787 mm.
