“…There are several known methods to improve antenna performance, especially in terms of bandwidth. The increase in bandwidth is carried out by using the proximity coupled feeding technique [2] [3], and the use of an integrated impedance matching network [4]. This type of proximity coupled feeding is a solution to increase bandwidth, with other advantages having a wider bandwidth and smaller dimensions than conventional antennas [1].…”

A rectangular patch antenna is a compact antenna. It is appropriate to a modern mobile communication application. The main drawback of the rectangular patch antenna is the bandwidth. It restricts the antenna's application. The natural dielectric replaces the artificial dielectric to enhance the bandwidth. A stripline feed of the rectangular patch antenna is replaced by a proximity coupled line feed. The method is predicted to enhance more than 10% of the antenna bandwidth with natural dielectric. Furthermore, the antenna with and without modification is referred to as an artificial and conventional antenna. The artificial antenna performances are simulated. The performances of the artificial antenna are compared to a conventional antenna. The result shows that the method can enhance the conventional antenna bandwidth by 13.82%. In addition, the method has reduced the size of the conventional antenna to 14.12% smaller. The method can be used as a solution for the miniaturization of a patch antenna size.
