The study of Microstrip patch antennas have made great progress in recent years. Compared with conventional antennas, Microstrip patch antennas have more advantages and better prospects. They are lighter in weight, low volume, low cost, low profile, smaller in dimension and ease of fabrication and conformity. Moreover, the Microstrip patch antennas can provide dual and circular polarizations, dual-frequency operation, frequency agility, broad band-width, feed line flexibility, and beam scanning omnidirectional patterning.

The microstrip antenna has features such as light weight, easily mountable and easy for mass production. A wideband suspended Hexagonal patch antenna with capacitive coupling is introduced for (2.26-3.72 GHz) Wireless applications.

Employing only a single patch, a high impedance bandwidth is achieved. The simulated percentage bandwidth is about 60.83%. The structure of the antenna consists of a perfect conductor on the top of a substrate (FR4 material) with a dielectric constant of about 4.4 and a height of 9 mm, which is backed with a perfect conductor ground plane. The impacts of different parameters of antenna are also studied in this article.
The Multiband Patch Antenna with Square and Hexagonal Shape for Different Wireless Applications
Fractal geometry involves a recursive generating methodology those results in the figure with infinitely convoluted fine structures. They do not use additional loading components and are simple and cost-effective to fabricate. They can be mounted to constraining form factors, such as the casing of hand-held transceivers. In this paper, a fractal antenna is designed with Square and Hexagonal shape and operating between 4-7 GHz. The proposed antenna with the rectangular ground plane is modelled and simulated with Finite Element Method (FEM) based High Frequency Structure Simulator (HFSS) and an improvement in performance parameters (Return loss, Bandwidth (BW) and VSWR) is observed with change in design parameters. Fractal antennas prove worthwhile, high performance, resonant antennas for many practical applications. It is usually fabricated as or on small circuit boards, they allow new versatility in their use with wireless devices. I. INTRODUCTION The term FRACTAL, that which mean wrecked or asymmetrical fragments. The development of the fractal geometry originally inspired from the pattern of nature. It is widely used in many streams of science and complex shapes found in nature such as trees, stars, and mountains etc [2]. There are several advantages of using fractal geometries in antenna design. First of all, it can reduce the size of the antenna, which makes it a good candidate for miniature antenna design. Basically, fractal geometries are self-filling structures that can be scaled without increasing the overall size [3]. Fractals can be used in two ways to enhance antenna designs. The first method is in the design of miniaturized antenna elements. These can lead to antenna elements which are more discrete for the end user. The second method is to use the self-similarity which provides flexibility in antenna by reducing the antenna size in horizontal and vertical direction. This would allow the operator to incorporate several aspects of their system into one antenna [4]. IFS also play an important role in the specification of fractal. Iterated mathematical process formed the shape of a fractal. So, the shape of a fractal is made up of overlapping smaller copies of itself, each copy is changed by IFS system. Such Fractal can be obtained by using computer graphics require particular mapping that is replicated over and over recursive algorithm. The best example is Sierpinski Gasket which is also known as Sierpinski triangle [5]. Benoit Mandelbrot described the term 'FRACTAL 'and he has described the relationship between fractal and nature using discovery made by Gaston Julia and Pierre Fatuous [6]. Its Latin name is fractus means 'broken': some of the parts have the same shape as the whole object but on a different scale [7]. This type of geometry became more popular in 1990. With the help of this geometry we can designed the multiband antennas as well as new dimension of antenna array. Fractal antenna has been become more popular because of its attractive features such as better input impedance matching, reduced mutual coupling in fractal array antenna, miniaturization and frequency independent [8]. Application of fractals to antenna design has proved to be a benefit to wireless communication system. Studies in this field proved that fractals result in high bandwidth, good gain and improved radiation pattern as compared to traditional antennas [9]. Fractal antenna has different structures like sierpinski gasket, sierpinski carpet, minikowski fractal antenna, and fractal tree antennas etc. If we conclude that certain electrical properties of an antenna are directly a function of certain physical properties of the antenna, then we must also conclude that significantly modifying these physical properties must significantly modify the antenna's electrical
Tunable and Dual Band Slot Loaded Hexagonal Microstrip Antenna for Wireless Communications
This article describes the design of single layer dual frequency microstrip antenna for IEEE 802.11b/Bluetooth and WiMAX applications. The new configuration of the antenna is achieved by using open hexagonal ring slot placed at the boundary of the hexagonal patch. The proposed dual frequency antenna exhibits two adjacent resonant modes with the same plane of polarization, radiation characteristics, and impedance characteristics and these modes are excited at frequencies near the fundamental mode TM 11 of the hexagonal patch without a slot. Compared with the conventional hexagonal patch, the proposed antenna can achieve a large amount of size reduction. It has also been observed that by controlling the width of slot and distance R 1 , the two frequencies f 1 and f 2 can have frequency ratio (f 2 /f 1) in the range between 1.28 and 1.44. The antenna is simulated and analyzed using Ansoft HFSS.

2021
A Compact Corner Split Ring with Split C Slot Rectangular Microstrip patch Antenna (CCSR-SCS) fed by a 50 Ω microstripline is discussed. A Corner split ring with C shaped slot has been etched in rectangular microstrip antenna. The slot increases the length of the surface current for the dominant mode TM10 leading to the decrease in resonance frequency. The size reduction along with proposed antenna Hexaband is obtained with the antenna and it is best suited for wireless communication. The proposed work is simulated using 3DEM of Mentorgraphics. The results show that Hexaband with compactness is achieved.
