<p>A first [c] and a second [d] conductive patch of a compact planar microstrip antenna are connected at a junction point [c/d] to shorten the length of the impedance transition from the center point, where the wave impedance vanishes, to the patch edge, where the impedance becomes very large. The second conductive patch [2w] is wider than the first conductive patch [2t] and one end [x] 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 decreases the size of the antenna greatly for the required frequency range.</p> |
