Elliptical Ring

A wide-band antenna coupling with an elliptical slot was discussed in this paper. To implement the wide band operation, an elliptical ring slot was etched on a polygonal patch. The properties of this design have been verified by using electromagnetic simulation software. Comparing to the conventional U-slot patch antenna fed by Π-shaped slot, the proposed structure is with the same impedance in bandwidth, but less than 10% in size.

Compact Microstrip Antenna

This work describes a compact microstrip antenna design for wide bandwidth applications. The proposed work introduces a methodology to improve the bandwidth, as well return loss by the defective ground structure (Extended F-Shape). As communication systems require small size, broadband and multiband frequency antennas, an inset line feed monopoles have to be ensured for fabricating broadband antennas. Intensive investigations are carried out in the proposed work to design a new antenna with broadband and multi-band properties. Simulations are performed by using the Ansoft HFSS Electromagnetic Simulation Software.

Design Techniques

Elliptical Micro-strip Patch Antenna (EMPA) has been emerged as a peculiar and significant category among the different shaped micro-strip patch antennas because of its circular polarization and dual-resonant frequency features with a single feed. Elliptical and its derived shapes such as semielliptical, half-elliptical, slotted-elliptical and elliptical ring are found to be particularly instrumental for bandwidth enhancement and these antennas find great applications in Ultra Wide Band (UWB) and Super Wide Band (SWB) communications. Compared to antennas with circular or rectangular shapes, the design of EMPA is a research area of high potential as there is higher flexibility in its design due to more degrees of freedom. The reported literature in the field of EMPA is very less and there is ample scope for new researchers to work on. This review paper is an attempt to summarize and critically assess the-state-of-the-art design techniques as reported in literature and understand their effects on performance of elliptical patch antenna for suggesting new research fronts in the field of EMPA.

The probe-fed rectangular patch antenna with the Minkowski fractal structure which for 2.45GHz was simulated by using high frequency electromagnetic simulation software HFSS V11.The Simulation results showed that it was similar to side-fed square patch antenna with the Minkowski fractal structure. The resonant frequency decreased with fractal iteration, and the size of the antenna could be miniaturized. And antenna pattern unchanged with fractal iteration mostly, which meet the application requirements basically.

Electromagnetic scattering simulation is an extremely wide and interesting field, and its continuous evolution is associated with the development of computing resources. Undeniably, antenna design at all levels strongly relies on electromagnetic simulation software. However, despite the large number and the high quality of the available open-source simulation packages, most companies have no doubts about the choice of commercial program suites. At the same time, in the academic world, it is frequent to develop in-house simulation software, even from scratch and without proper knowledge of the existing possibilities. The rationale of the present paper is to review, from a practical viewpoint, the open-source software that can be useful in the antenna design process. To this end, an introductory overview of the usual design workflow is firstly presented. Subsequently, the strengths and weaknesses of open-source software compared to its commercial counterpart are analyzed. After that, the main open-source packages that are currently available online are briefly described. The last part of this paper is devoted to a preliminary numerical benchmark for the assessment of the capabilities and limitations of a subset of the presented open-source programs. The benchmark includes the calculation of some fundamental antenna parameters for four different typologies of radiating elements.

Measurement Results

Ansoft HFSS electromagnetic simulation software was used in this study to simulate the design of two frequency band dual band coplanar antennas for WiMax (3.44GHz to 3.69GHz) and (5.25GHz to 5.85GHz) with center frequencies of 3.5GHz and 5.25GHz respectively. The steps of antenna design simulation are shown in figures of Return Loss, Current Distribution and 3D Radiation Pattern. Through continuous simulation, modification, and correction, the antenna can achieve the desired effect. Metal was used as the reflective material for the antenna designed, the antenna was covered by the material as a partition between the antenna and the metal, and FR4 was used as high-frequency circuit board (dielectric coefficient = 4.4). The simulation and measurement results were found to have consistent and good characteristics.
