An Object Is Placed 30 Cm To The Left Of A Converging Lens. Patch antennas come in various shapes and sizes and consist of a patch of metal directly above a ground plane. The main disadvantage of these antennas is their relatively large size compared to other types of antennas.

Patch antennas come in various shapes and sizes and consist of a patch of metal directly above a ground plane. For example, some patch antennas are approximately half a wavelength on each side. Rays of light entering a converging lens parallel to its axis converge at its focal point f.
The Main Disadvantage Of These Antennas Is Their Relatively Large Size Compared To Other Types Of Antennas.
For example, some patch antennas are approximately half a wavelength on each side. An expanded view of the path taken by ray 1 shows the perpendiculars and the angles of incidence and refraction at both surfaces. Figure 5.27 shows an example of a patch antenna.
Rays Of Light Entering A Converging Lens Parallel To Its Axis Converge At Its Focal Point F.
(ray 2 lies on the axis of the lens.) the distance from the center of the lens to the focal point is the lens’s focal length f. Patch antennas come in various shapes and sizes and consist of a patch of metal directly above a ground plane.
