“…As a result, the electric surface current density on the conducting surfaces is unknown, and the electric and magnetic surface current densities on the dielectric surfaces are weird. These currents, in addition to the wind that blows across the dielectric zone, are the primary causes of the electric and magnetic fields that may be found in the region [24].…”

Microstrip patch antennas are becoming increasingly popular because they are small, have low profiles, are easy to integrate, are very cheap, and work well. For this reason, this antenna could be used for wireless communication systems. This research paper reviews and studies 28 GHz microstrip patch antenna for wireless applications. Different substrate materials have been used to make these antennas, such as FR-4 (loss), FR-4 Epoxy, Rogers RT/droid 5880, TLC-30, Rogers RT/droid 5880 LZ, and others. Different substrate materials and shapes were used to make microstrip patch antennas with a frequency of 28 GHz. This article discusses the different sizes of antennas, the other geometric shapes antennas can take, the different ways antennas' properties can be analyzed, and the different types of antennas. It will also talk about the material, thickness, loss tangent, return loss, bandwidth, voltage standing wave ratio (VSWR), gain, efficiency, and directivity of the substrate. This antenna is used for super-high-frequency (SHF), radars, commercial wireless local area networks (LANs), cell phones, and other wireless communications systems.

“…This makes the electric surface current density on the conducting surfaces unknown and the electric and magnetic surface current densities on the dielectric surfaces strange. These currents and the wind that blows through the dielectric zone are what cause the electric and magnetic fields in the area [19].…”

This article presents a review of several microstrip patch antennas for 3.5 GHz wireless applications. Different substrate materials, FR-4 (loss), FR-4 Epoxy, Rogers RT/droid 5880, TLC-30, and Rogers RT/droid 5880 LZ, are used. In recent years, wireless antenna applications have increased, including biomedical appliances, internet of things (IoT) terminals, edge devices, radars, mobile phones, and many more. In this work, several articles were reviewed and investigated, and several microstrip patch antennas with a resonance frequency of 3.5 GHz were designed using different substrate materials and shapes. This article also discussed the geometric shapes of antennas, antenna properties, sizes of substrate materials, loss tangent, thickness, return loss, bandwidth, voltage standing wave ratio (VSWR), gain, efficiency, and directivity. Several software is used for design and simulation, including computer simulation technology (CST), high-frequency simulation frequency (HFSS), and advanced design system (ADS), FEKO, and MATLAB. The main goal of this paper is to talk about different wireless application papers that work in the S-band at a frequency of 3.5 GHz and have been published in various international journals and conferences.

“…However, the major weakness of MSAs is the suffering from various disadvantages like low gain, high-quality factor and narrow impedance bandwidth etc. (5). To overcome this weakness of MSAs, several various methods have been suggested, such as using different shapes for patch, proximity feeding, stacked patch, defected ground structures, metamaterials, fractals, multimode techniques and using thick dielectric substrate with low permittivity (6)(7)(8)(9).…”

In this work, new structures of circular microstrip antenna based on slots are designed and simulated to operate with triple band applications. These slots are annular ring and rectangular shapes in different sizes. The annular ring slot is etched inside the circular patch while the other two rectangular slots are etched on the circular patch edge. The suggested antennas are simulated using version 13 of Ansoft High Frequency Structure Simulator (HFSS). The various parameters such as input impedance, reflection coefficient, gain, radiation patterns and surface currents were investigated. The present results observed that the optimum antenna designed is resonating at three frequencies 2.695, 5.799 and 8.323 GHz. Also, the bandwidths of simulated reflection coefficients at -10 dB are 106, 204 and 371 MHz which are identical with the S-, C- and X-bands frequencies, respectively. Therefore, the optimum antenna designed can be used in the space saving applications in addition to its important role in variety applications at these three frequency bands.
