زيادة عرض الحزمة لهوائي شريطي مكون من نصفي قرص دائري مختلفين في نصف القطر

الملخص EN

Simulation of micro strip antenna as two half disk with different two radii is achieved, using Micro Wave Office 2000 (MW02000) depending on Moment Method (MoM).

By considering decreasing radii exponentially with respect to the circle angle.

We found an increase of the bandwidth from 6.4 % up to 10.65 % nearly, when we use foam with dielectric constant er = 1.07.

also the center of the resonant frequency was shifted to a new value.

By applied the method with different dielectric constants and radii we obtaind increase of the bandwidths for all cases.
