Closed‐form equations for the characteristic impedances of even and odd modes are given for an enclosed cylindrical microstrip line with finite thickness (CMSWFT) with the use of the conformal mapping technique and the available equations for microstrip lines. The enclosed structure is also suitable from the EMI and EMC points of view. A compact 1:5‐way, equal in phase, power divider/combiner has been realized with the use of this structure at 350 MHz. This power divider/combiner is suitable for high‐power applications in VHF and UHF bands. The limitations regarding the maximum output ports are discussed. Good performance of the power divider confirms the theoretical procedure. © 1996 John Wiley & Sons, Inc.
