TELKOMNIKA Telecommunication Computing Electronics and Control, 2022
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 (11) 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.

Design of Slotted Microstrip patch Antenna for 5G Application
The 5G cellular system is expected to have a wide spectrum. The antenna design for 5G application is challenging task. This paper consists of the antenna design for the 5G application which will use microstrip patch antenna with slots loaded on the radiating patch to improve the performance of antenna in terms of gain, radiation pattern and bandwidth at 5-6GHz spectrum. Microstrip antennas have several advantages like low profile, low cost and ease of fabrication. Major disadvantage of the microstrip patch antenna is its inherently narrow impedance bandwidth. By loading some specific slot in the radiating patch of microstrip antennas, compact or reduced size microstrip antennas can be obtained. Loading the slots in the radiating patch can cause meandering of the excited patch surface current paths and result in lowering of the antenna's fundamental resonant frequency, which corresponds to the reduced antenna size for such an antenna. In this paper FR4 material is used for the 1.6mm thick substrate.
Design and study of a microstrip slot antenna operating at 2.8/3.1/3.6/4.7/5.4 GHz
MATEC Web of Conferences, 2017
A novel design of a multi band microstrip antenna is presented in this work. The double modified U slots planar patch antenna is designed, simulated and fabricated to operate at 2.8 GHz (between 2.794 to 2.846 GHz), at 3.1 GHz (between 3.145 to 3.196 GHz), at 3.6 GHz (between 3.56 to 3.3.644 GHz), at 4.7 GHz (between 4.684 to 4.772 GHz) and at 5.4 GHz (between 5.423 to 5.526 GHz) for WiMAX/WLAN applications. One of the main challenges was keeping a low profile and low cost substrate (1.2mm and FR4 respectively) with penta-band frequency response without scarifying these characteristics. Each resonant frequency is accomplished by modifying each U slot and patch radiator itself. Simulations had been conducted using HFSS software and measured parameters such as reflection coefficient (S11 parameter) was performed with a vector network analyzer. Measured results confirm simulated results that the antenna could work within mentioned frequencies. Parametric study was conducted in order to study the effect of slots variation over the design.

Design of Microstrip Patch Antenna for Radar and 5G Applications
ESP Journal of Engineering & Technology Advancements, 2023
From IG to 4G, there have been four generations of advancements in mobile wireless technology. The use of the internet by more people is currently causing growth in wireless communication technology. Higher data rates are drawing a lot of attention due to wireless transmission's lack of flexibility, poor quality, lost connections, and insufficient coverage. The current (4G) generation of wireless connectivity is unable to satisfy customer needs. At the moment, several mobile technologies operate on the 900, 1800, 2100, and 2300 MHz frequencies. Low frequencies result in extensive coverage and minimal attenuation. 5G wireless communication research has been implemented to address this issue. The new version (5G) has several key benefits, including a larger bandwidth, improved cell resolution, and the capacity to offer tens of thousands of users data speeds of at least one gigabit per second. Most 5G research takes place between 6 GHz and 100 GHz. One of 5G's objectives is to connect millions of devices. This technology might be used in smart homes. Higher frequency bands have recently seen a lot of scholarly interest in the development of Ku-band antennas (12-18 GHz). The Ku band is used for a variety of things, including broadcast satellite services, fixed satellite police radar systems, and television transmission over networks. Several literature reviews on Ku-band and 5G antennas have recently been published. Mobile phones use Microstrip patch antennas more frequently due to their small size, affordable price, and lightweight nature. Examples include biological applications, aircraft, satellite communications, radars, and more. A microstrip antenna has good return loss, voltage standing wave ratio (VSWR), and capacity. Patch antennas have a number of advantages, such as low weight, low profile planar design, inexpensive manufacturing, and microwave integrated circuit technology that enables integration. For the purpose of creating a microstrip patch antenna, the dielectric substrate has a ground plane on one side and a radiating patch on the other. Feeding is accomplished using an electromagnetically connected (EMC) microstrip patch antenna with a coaxial probe and a microstrip line. The E-shape microstrip patch antenna is ideal for wireless communications systems, medical applications, mobile phones, pagers, GPS, radar systems, and satellite communications systems, as well as military applications such as rockets, aircraft missiles, and other similar devices. One of the antenna types in the telecommunications industry that is expanding quickly is the microstrip antenna
