Ultra WideBand Matching of the Rectangular Microstrip Patch Antennas (RMPA) Using Microstrip Non Uniform Transmission Lines (MNUTL)
Simulating and modeling configurations of Rectangular Microstrip Patch Antennas (RMPA) are dealt with in this paper. Microstrip Non Uniform Transmission Lines (MNUTL) are used to feed the RMPA leading to ultrawideband impedance matching. Microstrip linear and sinus
tapered characteristic impedance lines and Microstrip uniform lines are both taken to feed the same antenna patch
and finally to compare their performances. The analysis is based upon the Finite Difference Time Domain method FDTD combined with the Absorbing Boundary Conditions Perfectly
Matched Layers (ABC PML). An RMPA whose resonance frequency is 7.5 GHz is analyzed over a frequency band from
5GHz to 16GHz by calculating the return loss and the input impedance from the time-domain simulated data.
Keywords: Microstrip Antennas, MNUTL, FDTD-PML technique, Ultra Wideband impedance matching.
