Antenna design
The geometry and configuration of the proposed UWB notch antenna with
the notch at 5.5 GHz is shown in the figure 1 (a) and (b). The antenna
is simulated and fabricated on a FR4 epoxy substrate with the dielectric
constant εr =4.4 and height h =1.6 mm. It
has a circular radiating element of radius Rpatch=5.25
mm on the front surface of the rectangular substrate of dimension
(LsubxWsub) 15x17 mm2.
This radiating element is fed by a 50-Ω
