“…In addition to these methods, there are also several methods used on microstrip antennas, including the wall method [4], slot method [5], metamaterial ring method [6], Substrate Integrated Waveguide (SIW) method [7], and the Defected Ground Structure (DGS) method [8]. The wall method is a method conducted by providing a metamaterial barrier, such as a wall between the radiating antennas.…”

Wireless Fidelity (WiFi) devices are often used to access the internet network, both for working and in information searching. Accessing the internet can be administered anywhere provided that the area is within the WiFi devices range. A WiFi device uses 2.4 GHz and 5 GHz operating frequencies. There were several methods employed in the previous studies so that an antenna design could work in two different frequencies, i.e., winding bowtie method, Sierpinski method, and double-circular method. This paper employed a simple method, the slit method. The objective of this paper is to discover a simple antenna model that works on 2.4 GHz and 5 GHz frequencies. This paper employed a square patch microstrip antenna with a slit method. The dimensions of the designed square patch microstrip antenna were 42.03 mm × 27.13 mm × 0.035 mm. The antenna worked at 2.4 GHz and 5 GHz frequencies. The obtained simulation results after the optimization showed that the square patch microstrip antenna using the slit method acquired a value of S11 (return loss) of -10.15 dB at a frequency of 2.4 GHz and -37.315 dB at a frequency of 5 GHz.

“…Mutual coupling arises from mutual influence between one against another patch antennas, causing the S-parameter values of the antenna such as gain, return loss, radiation pattern, efficiency, channel capacity, matching impedance, and the emitted power to decrease. This research refers to previous studies that have been investigated using microstrip antennas while regulating the value of mutual coupling (Ferendeci 2011) is obtained by giving a ring and square metamaterial between the antenna patches (Goran, Setijadi, and Hendrantoro 2018).…”

The antenna performance is seen from the S-parameter value. The Sparameter graph can be seen as the return loss (S11, S22) and the mutual coupling (S21, S12) value. This research focuses on analyzing mutual coupling on Square and Vivaldi array antennas using the ring metamaterial method. The value of mutual coupling is considered very important to analyze because it affects the performance of the antenna in which is arranged in an array. The simulation results of the mutual coupling value obtained on a square array antenna use a ring metamaterial is -17 dB at a frequency of 2.4 GHz. Meanwhile, the Vivaldi array antenna uses a ring metamaterial that produces a mutual coupling value of -13.840744 dB at a frequency of 3.0162 GHz. The factors that affect the square array antenna so that it becomes the best to suppress the mutual coupling value between antenna elements are a selection of metamaterial shape and proper placement between the antenna array elements is arranged horizontally.

“…Mutual coupling effects can cause changes in antenna parameters such as radiation pattern, return loss, directivity, low side lobe level (SLL), gain, impedance matching and transmit power [13], [14], [15], [16]. Several ways to reduce the effect of mutual coupling is to use a metamaterial structures [17], exponential corrugated truncated (ECT) structures [11], defected ground structures (DGS) [18]. To our knowledge, the effect of mutual coupling between subarray elements of a rectangular antenna and coaxial feeding has never been reported.…”

Wireless communication for the future will use 5G standards, supported by an antenna system with Massive MIMO technology incorporating subarrays. A subarray microstrip antenna that has small element spacing will result in mutual coupling effects. This paper proposes design of a two rectangular subarray antenna with coaxial feeding for massive MIMO development and analysis the effect of mutual coupling at varying spacing element. Antennas are designed and simulated, namely a single antenna, a two element antenna arrayed in the E-plane and a two element antenna arrayed in the H-plane. The simulation results show that the mutual coupling of the two antenna elements arrayed in the E-plane for all element spacing is less than -20 dB, which means the mutual coupling effect can be ignored. Whereas the mutual coupling of the two antenna elements arrayed in the H-plane for all spacing elements is greater than -20 dB, which means the value of the mutual coupling must be considered. The bandwidth of the two element subarrays on E and H-plane is 77.3-88.5 MHz depending on the element spacing, which is still below 100 MHz required for 5G application.
