Effect of slot on patch antenna

A patch antenna is literally a patch of metal or other conductor on a flat surface. There may or may not be a ground plane on the other side of the substrate. The directionality, gain, polarization, and impedance are a function of the size and shape, and placement of the feed line. Most GPSs use a patch antenna.

On the Use of Slots in the Design of Patch Antennas experimental study of the geometry shown in Fig.2.6. A patch antenna with a parasitic patch is sometimes known as an electromagnetically coupled patch antenna. The experiment was performed at NASA Lewis Research Center (later renamed Glenn Research Center) by my MS student J. Bobinchak, in collaboration with Dr. R. Q. Lee of NASA.

SHIVNARA YAN et al.: SLOT- LOADED RECTANGULAR MICROSTRIP PATCH ANTENNA 425 the present work, the patch is fed by co-axial cable (50 ohm). Since the slot is thin, the voltage can be sinusoidal with zero voltage across the ends of slot. Design of Circular Micro strip Patch Antenna with - ijert.org the transmission. Circular Micro strip patch antenna were successfully incorporated with H, U, +, Rectangle & square slots The effect of varying the slot width and slot length were studied under great details with the help of experimental results. The proposed patch yield desirable results throughout the operating frequency range. COUPLING EFFECT OF SLOT APER TURE COUPLED MICROSTR …
