Abstract :
In this work the area miniaturization of a rectangular microstrip patch antenna by inserting a slot parallel to the radiating edges, is investigated in relation to the quality factor. This slot forces the surface currents to meander, thus artificially increasing the antenna´s electrical length without modifying the patch´s global dimensions. A significant decrease in the resonant frequency is observed, depending on the slot´s length and width. The resultant antennas can be characterized as small antennas in accordance to the relevant fundamental limitations.
