| Abstract | ||
| In this paper a new rectangular microstrip patch antenna for wireless communication systems is designed and tested practically. The rectangular patch is modified by changing the basic parameters, adding triangular pieces to the bottom patch ,making L slots in the edge of the patch and etching rectangular slot in the ground plane .The optimized antenna (final modification) give a band of (2.26-20) GHz in which the return loss S11 is less than -10dB and a gain of (0.8-8)dBi . The slotted rectangular antenna is fabricated on FR4 having relative dielectric constant of €r=4.3 and loss tangent of 0.02.The dimension of the patch is (42×40×1.6)mm3 .The slotted rectangular patch is tested practically using the Vector Spectrum Analyser (VNA) for insertion loss (S11),voltage standing ratio(VSWR), and input impedance . It is found that the simulation results agrees(mostly) with the practical results. The antenna is fed by 50Ω transmission line. | ||
