(a) Simple patch antenna For simple patch effects of height of substrate h=1.57 , 1.59,1.6,2 mm has been shown below it has been found that the height of the substrate is increases their return loss also increases. Fig.3 Input reflection coefficient of simple rectangular patch antenna to show the effect of

In this paper, a study on the effect of rectangular slot in a non-radiating edge of rectangular microstrip patch antenna on the miniaturization of the antenna has been presented. It has been investigated from parametric studies that frequency becomes lower due to the increase of effective electrical path length along the slot dimensions.

Effect of Slot Rotation on Rectangular Slot based Microstrip ...

What is the difference between slot antenna and patch ... 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. Effect of Capacitive loading on slot loaded Dual Band ... location of the slots with respect to the patch is defined by the quantities w and l which are very small with respect to the dimensions L and W of the patch. The antenna may be fed with either an aperture or a probe feed [1]. Fig 3 top & side view of designed antenna with parallel slots Authors have c probe feeding.
