Abstract :
This paper presents the design of a perpendicular slots antenna on a sectoral cylindrical cavity excited by a probe. To realize the impedance characteristics of antenna, the integral equations of the unknown magnetic currents over the pair of slots and electric current at the feed probe have been established base on the field equivalent principle and enforcing the boundary condition. The Galerkinpsilas method of moment will be applied to obtain the unknown coefficients for evaluating the unknown electric current densities at the probe. Finally, the numerical result of the reflection as the impedance characteristics of this antenna is demonstrated and verified with experimental result as a function of frequency. Good agreement between simulated and measured results is obtained.
