Abstract :
A new conical microstrip antenna with uniform substrate is investigated. The far field radiation patterns of wraparound microstrip antennas mounted on such a structure are studied theoretically. The patches are replaced by equivalent magnetic currents which are obtained from a cylindrical microstrip antenna under a hypothesis based on cavity model theory. The radiation fields are then determined using the model expansion technique in spherical coordinate system. Results for a wrap-around antenna of half-wavelength in width excited by TM01 are given. They are verified accurate and efficient
