In this project, the different locations of the quadruple P-spiral split ring resonator (MI-SRR) structure are embedded in the basic rectangular patch antenna. It started with a basic rectangular microstrip patch antenna that simulated in CST Microwave Studio software. After that, four different locations (Location A, Location B, Location C and Location D) of QPS-SRR had chosen to compare its performance of return loss, resonant frequency, surface current radiation pattern, and gain. Location A is representing the antenna with the QPS-SRR at the center part of the patch while Location B has the QPS-SRR at the upper part of the FR-4 substrate. For the Location C and Location D represent the antenna with MI-SRR at the ground at antenna with MI-SRR at the other layer, respectively. Compared with the basic rectangular antenna with only – 27.082 dB, the best return loss was reached by Location A with - 34.199 dB with resonant frequency at 2.390 GHz, while the Location C only shifted the minor value to 2.394 GHz with only - 25.13 dB.

This paper presents the design and simulation of a microstrip patch antenna (MPA) which is modeled by placing several rectangular copper layer with conductive characteristics on a substrate material with dielectric constant 3.0 and 22x18x1 mm3 geometry. This microstrip path was designed with copper material which had a very thin thickness for patch and ground. In this study, a change in resonance frequency and return loss characteristics were observed for several substrate thickness values. The radiation characteristics of the single and dual band microstrip patch antennas (MPAs) are analysed in the frequency range of 5 – 25 GHz. The microstrip patch antenna (MPA) radiate at a frequency of 15.32 GHz with -45 dB return loss. For the designed single and dual band MPA design, some electromagnetic properties such as return loss, surface current and radiation patterns were simulated. The characteristic of goods and chattels of the proposed antenna are analyzed by using the software CST Microwave Studio.
