Relationship Between Co-Axial Probe Feed and Inset Feed in Rectangular Microstrip Patch

In this chapter, an equation is obtained using curve fit formula that shows the relationship between the simulated co-axial probe feed distance and theoretically inset feed distance in rectangular microstrip patch antenna. The simulation process is performed using IE3D simulation software tool and theoretical calculation performed by the cavity model. Using this equation, one can avoid hit and trial for getting simulated co-axial feed distance by knowing theoretically inset feed distance. A ratio also has been developed between co-axial probe feed and inset probe feed.
