This paper presents a microstrip patch antenna with diagonally symmetrical slots for RFID applications. The unequal length center slots with four rectangular slots on its diagonal axes are embedded onto the square patch radiator. These slots are introduced to achieve compact size. The coaxial feed is used to excite the proposed antenna. The antenna is fabricated using FR4 Dielectric Substrate (relative permittivity =4.4, loss tangent=0.001) and coaxial feed. These designed antennas are fabricated and used in real time applications. Microstrip Patch Antenna using IE3D software and study the effect of antenna dimensions Length (L),and substrate parameters, relative Dielectric constant, substrate thickness (t) on the Radiation parameters of Bandwidth and Beam-width.

An antenna plays a major role in the field of communication engineering. In this paper we have designed a 12 sided polygon shaped patch Microstrip antenna and simulation has been done using IE3D simulator software version 14.0. The designed antenna has following dimentions: 32.5mm×39mm (Ground plane), 26mm×26mm (patch), and substrate thickness of 1.6mm and FR4 material is used as dielectric having relative permittivity of 4.2 and loss tangent of 0.0013 at a frequency of 2.4GHz. The different parameters of the designed antenna such as VSWR, return loss, gain, efficiency, axial ratio etc. have been studied.

In this paper a novel design of compact microstrip antenna with impedance of 187Ω is proposed. The antenna consists of a rectangular patch with slits on the top face and a partial ground with slots at the rear end. The antenna is fabricated on FR-4 epoxy dielectric with relative permittivity of 4.4. The designed antenna has the capability of operating at 5.78GHz for wireless applications. Single element, 1x2 array and 1x4 array has been designed and it is studied that from single element design to the 1x4 array design the antenna gain has kept on increasing respectively. The proposed antenna has Omni-directional radiation pattern and it also poses a relatively excellent return loss. Radiation pattern is measured in antenna anechoic chamber. Feed line used has characteristic impedance of 50Ω. Antenna parameters such as return loss and radiation pattern show reasonable agreement with the simulated results. The antenna simulation is done using the Zeland Ie3D simulation software.

This research work presents design, simulation and comparison of microstrip patch antenna designed using different feed techniques. The Microstrip feed techniques are microstrip line feed, inset feed, coaxial feed, aperture coupled feed and proximity coupled feed. We have chosen to compare co-axial feed and microstrip inset feed due to the advantage that it can be easily fabricated and simplicity in modelling as well as impedance matching. The objective of this paper is to design a rectangular microstrip patch antenna which operates in C-band at 5.2 GHz. Microstrip antennas are most suited for aerospace and mobile applications etc. They can be designed in variety of shapes. Therefore, method of moments based IE3D software is used to design a Microstrip Patch Antenna with enhanced gain and bandwidth. IE3D is an integrated full-wave electromagnetic simulation and optimization package for the analysis and design of 3D and planar microwave circuits. The IE3D has become the most versatile, easy to use, efficient and accurate electromagnetic simulation tool. It computes most of the useful quantities of interest such as radiation pattern, input impedance and gain etc. The microstrip patch antenna is designed and simulated using high frequency simulation software IE3D and it is designed to operate in C-band frequency range (4GHz-8GHz). These antennas are designed using RT-duroid dielectric substrate with the permittivity εr=2.2. In this analysis, we have compared the antenna parameters such as gain, impedance, reflection coefficient, VSWR and further the performance of these two feed techniques discussed. The antenna has been designed for the range 5-6 GHz; hence this antenna is highly suitable for C-band applications wimax applications, and other wireless systems.

A finite Difference Time Domain (FDTD) analysis of a polygonal Fractal Antenna with Uniaxial Perfectly Matched Layer (UPML) boundary conditions is presented in this paper. The software simulations are performed on the same fractal antenna using Ie3d software which works on Method of Moments (MoM). The results from FDTD simulations and ie3d nearly matches. Impact of the fractal antenna on bandwidth improvement is observed and analysed. A parametric study is performed to locate the optimum feed point for Ultra-Wideband (UWB) operation. and bandwidth enhancement is observed ranging from 2.2 GHz to 9.8 GHz making it suitable for UWB Applications the comparative study is performed by taking the bandwidth gain and volume of the antenna. The problem in implementing the geometry in FDTD involving sloped edges leading to the error due to staircase approximation is also discussed. The efficiency of the antenna is between 80% to 90% in the entire band. The gain of the antenna in the final iteration is increased up to 6 dB, Axial ratio is below 1.2dB and the directivity is above 6.5 dB.
