In order to obtain a maximum radiation efficiency and frequency bandwidth a thick patch substrate with a low 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.

The current goal is to enhance the bandwidth of a microstrip antenna while using a thin substrate (less than 0.01λ 0). 1. These diagrams compare (a) the proposed microstrip antenna with (b) a conventional microstrip antenna. To meet this goal, a broadband low-profile microstrip patch antenna with a U-shaped parasitic element was investigated.

Microstrip patch antennas fall into the category of printed antennas: radiating elements that utilize printed circuit manufacturing processes to develop the feed and radiating structure. Of all the printed antennas, including dipoles, slots and tapered slots, microstrip patches are by far the most popular...

that addition of superstrate layer to U slot patch antenna is enhancing the bandwidth of aperture coupled microstrip antenna, but this result is not as encouraging as in the case of probe fed microstrip antenna with U slot and addition of superstrate layer on it. This may be due to the fact that Dual-polarized slot-coupled planar antenna with wide ...
