IAES Nawala: Microstrip patch antenna

Greetings, fellow Nawala! May you always be in good health.

This is the IAES Nawala of the Institute of Advanced Engineering and Science. Today we will share some news about microstrip patch antenna. A microstrip patch antenna is a flat planar antenna used for wireless communication. They are compact, unobtrusive, and suitable for applications such as satellite communications and RFID devices. According to Suriyan and Ramaingam (2023), a microstrip patch antenna is an essential component in wireless communication systems and has various benefits in various fields such as radar, GPS, and mobile communication. Various methods have been developed to improve the performance of these antennas.

The implementations of the microstrip patch antenna for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) are analyzed in the literature in this research. Dual or multiband antenna has played a significant part in meeting the expectations of wireless service in this quickly developing world of wireless communication. Basically, a transitory guide, an antenna is a device that emits or absorbs radio waves. Numerous benefits exist for microstrip patch antennas, including affordability, portability, simplicity of construction, and compatibility with integrated circuits. This has several important uses in the military, radar, mobile communications, global positioning system (GPS), remote sensing, and more. In mobile devices like portable computers and smartphones, WLAN and WiMAX are often used.

The development of this method started by Altufaili et al. (2022) regarding circular microstrip patch antenna has been designed and simulated for 5G applications. This antenna meets the system requirements of large bandwidth, compact size, and high data rate. The design includes a circular geometry with two circles: a first circle with a radius of 2.5 mm and a second circle with a radius of 1 mm. Simulated using microwave studio technology, the results show promising performance for 5G applications with compact size, high efficiency, and multiple resonant frequencies.

Using circular geometry has a great influence on many fields of science and engineering, one of which is antenna. Communication systems were oriented towards fifth generation (5G) because of large- bandwidth systems, compact requirements, high-data rates. In this research, a design and simulation are made to a microstrip circular patch antenna. The patch has two circles a compact structure of the first circle radius is 2.5 mm and second circle radius is 1 mm with thickness 0.35 mm. The proposed antenna has three resonant frequencies 41.08 GHz with a return loss of -12.4 dB, 47.4 at -18.86 dB and 54.4 at return loss -24.3 dB. The bandwidths are 150 MHz, 222 MHz and 219 MHz, the gains of three resonant frequencies are 6.16 dB, 9.89 dB and 5.54 dB, with efficiency of 98%. A technique of inset feed transmission line was utilized to match the fifty Ω microstrip feedline and the radiating patch. Based upon the proposed design, a Roger RT Duroid 5880 substrate that possesses loss tangent of 0.0009 with a height of 0.5 mm and a dielectric constant of 2.2 is employed. A computational process is conducted and analyzed by the use of computer simulation technology microwave studio.

The development was continued by Didi et al. (2022), who developed a microstrip patch antenna with a rectangular slot designed for 5G applications at 28 GHz frequency. The antenna design includes the use of a rectangular slot with dimensions of 2.5 mm x 5 mm placed in the center of the patch to increase the antenna bandwidth. With the rectangular slot on the transmitter patch, this antenna can be used for high-speed data transmission in 5G networks.

In this paper, we present a study and design of a rectangular-shaped microstrip patch antenna with a rectangular shaped slot at the operating frequency is 28GHz, for fifth generation (5G) wireless applications, using the microstrip line technique for feeding. The objective of this slot is to contribute to the improvement of antenna performance. This antenna is built on a Roger RT duroid 5880 type substrate having a relative permittivity equal to 2.2, a height of h = 0.5 mm, and a loss tangent of 0.0009. The compact size of this antenna is 4.2 mm × 3.3 mm × 0.5 mm. The simulations of this antenna were performed using high-frequency structure simulator (HFSS) and computer simulation technology (CST) software whose main purpose is to confirm the results obtained for this proposed antenna. The results obtained during these simulations are as follows: resonant frequency of 27.97 GHz and reflection coefficient) of -20.95 dB, bandwidth of 1.06 GHz, a gain of 7.5 dB, radiated power of 29.9 dBm, and efficiency of 99.83%. These results obtained by this proposed antenna are better than those obtained from already existing antennas that are published in current scientific journals. Consequently, this antenna is likely to satisfy the needs for 5G wireless communication applications.

Rana et al. (2023) continued by developing a microstrip patch antenna designed and simulated for wireless applications at 3.6 GHz. The antenna has a resonant frequency of 3.6 GHz and a bandwidth of 100 MHz, with a gain of 5.5 dBi. This antenna shows promising results for use in wireless communication systems.

In this study, a microstrip patch antenna that works at 3.6 GHz was built and tested to see how well it works. In this work, Rogers RT/Duroid 5880 has been used as the substrate material, with a dielectric permittivity of 2.2 and a thickness of 0.3451 mm; it serves as the base for the examined antenna. The computer simulation technology (CST) studio suite is utilized to show the recommended antenna design. The goal of this study was to get a more extensive transmission capacity, a lower voltage standing wave ratio (VSWR), and a lower return loss, but the main goal was to get a higher gain, directivity, and efficiency. After simulation, the return loss, gain, directivity, bandwidth, and efficiency of the supplied antenna are found to be -17.626 dB, 9.671 dBi, 9.924 dBi, 0.2 GHz, and 97.45%, respectively. Besides, the recreation uncovered that the transfer speed side-lobe level at phi was much better than those of the earlier works, at -28.8 dB, respectively. Thus, it makes a solid contender for remote innovation and more robust communication.
