“…The second literature is research on circular patch antenna substrate with styrofoam material host was modified by attaching a number of thin conductor wires through the substrate in 82 and 110 pieces. This research can prove an increase in relative permittivity of 167% for 82 wires and 270% for 110 wires [10].…”

The circular patch microstrip antenna is a device that supports 5G technology because it has a low profile and small dimensions. The circular patch antenna generally constructs of 3 layers of an electromagnetic material. The materials are a good conductor as the radiator and the ground plane and a natural dielectric as the substrate. Along with telecommunication developments, research in the field of antennas is significantly growing. The characteristics of the antennas must be adaptive to these telecommunication developments. One of the antenna research as the solution is an introduction to artificial electromagnetic material. Artificial dielectric is one of the artificial electromagnetic materials. As we have known, a single circular patch antenna has a narrow bandwidth (less than 5% of the center frequency) and a low return loss. This paper proposes an open-ring artificial dielectric. The proposed artificial dielectric is used to improve the bandwidth and the return loss. Furthermore, the circular patch antenna with and without the open-ring dielectric is proposed and conventional. The result shows that the proposed antenna has a wider bandwidth, 8.94%, a higher gain, 0.78 %, and a higher return loss at the center frequency, 5.25% higher than the conventional antenna. From these results, the open-ring artificial dielectric can improve the characteristics of the conventional antenna.

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.

“…Configuration of small conductors such as diameter, length, and distance between conductors on the substrate can affect the relative permittivity to be achieved [6]. Natural dielectric materials can be engineered by exploiting the nature of conductors and dielectric materials in response to an electric field [5]. As we know, the conductor and dielectric response to the external electric field.…”

This paper presents a comparison of the performance of two circular patch antennas. The antennas use a natural Taconic RF-60A with and without modification using laminating metal strips as the substrate, respectively. The first and the second antenna are referred to as a conventional patch antenna and an artificial patch antenna. Laminating metal strips at the natural substrate is predictable will change the antenna performances, such as a gain, a bandwidth, and a pattern. The comparison is conducted using an experimental simulation. The artificial patch antenna has some advantages using simulation optimization in such dimensions and antenna parameters. It has a bandwidth of 49.5 MHz or 21.42 % wider than the conventional patch antenna. A return loss at the centre frequency is 2.97 dB or 9.17 % higher than the conventional patch antenna, and a half-power beamwidth is 0.6° or 0.63 % wider than the conventional patch antenna. Although the artificial patch antenna has a gain of 0.68 dB or 13.47 % lower than the conventional patch antenna, to work at the same frequency of 1.8 GHz, the artificial substrate antenna requires an area of 40.67% smaller than the conventional substrate antenna. From these results, the artificial antenna has a good potential in miniaturizing the patch antenna device size.
