Abstract
A first and a second conductive patch of a compact cylindrical microstrip antenna are connected at a junction point to shorten the length of the impedance transition from one edge, where the wave impedance vanishes, to the other patch edge, where the impedance becomes very large. The second conductive patch is wider than the first conductive patch and one end of the first conductive patch is shorted with the ground plane. The effective impedance to be satisfied by the narrower strip at the junction is greatly reduced by the presence of the junction of two different patches, which substantially decreases the size of the antenna at a given operation frequency.
