Abstract :
The characteristics of a microstripline-fed cylindrical slot antenna are presented. The integral equation, which involves spectral domain Green´s functions and unknown slot electric field, is numerically solved using the method of moments. Computed results are compared with a slot antenna on a planar surface to demonstrate the validity and accuracy of the method. The effects of the size of the cylinder on the input impedance and far-field pattern are investigated
