WebSlot Antenna. Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide. But also older large phased array antennas used the principle because the slot radiators are a very inexpensive way for frequency scanning arrays. . Slot … WebFigure 1. Geometry of the basic aperture coupled microstrip antenna. length of tuning stub: The tuning stub is used to tune the excess reactance of the slot coupled antenna. The stub is typically slightly less than λg/4 in length; shortening the stub will move the impedance locus in the capacitive direction on the Smith chart.
