heal.abstract	Microstrip structures with a nonplanar shape have been extensively analyzed and studied due to their numerous practical applications. The present work examines a cylindrical microstrip with radially inhomogeneous substrate (cladding) and an axially infinite metallic patch. The permittivity follows a power law inside the cladding, and the Helmholtz equation possesses therein an analytical solution employing Bessel functions of noninteger order. The device is excited by a two-dimensional point source located into the substrate. The current on the patch is determined through an integral equation solved by the method of moments. Different dielectric constants for the cladding and electrical sizes of the microstrip, various positions of the excitation source and angular extents of the patch are considered. Their effects on the operation of the device are shown and discussed.	en
