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. Analysis of slot-loaded rectangular microstrip patch antenna 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. On the Use of Slots in the Design of Patch Antennas A dual-band rectangular patch antenna with a frequency ratio less than 2 can also be obtained by loading the patch with two narrow slots etched inside the patch, as shown in Fig.3.9. Maci (1995) demonstrated that, if the slots were placed at locations where the current of the lower mode is near minimum while the current for Analysis of slot-loaded rectangular microstrip patch antenna
patch antennas. In particular, the U-slot patch [1] enable a single patch single layer microstrip antenna to attain over 30% impedance bandwidth. The use of thick and low permittivity substrates is the main reason for achieving wide impedance bandwidth. In this context, the present study investigated the possibility of designing
