-Wide band truncated rectangular microstrip antenna with H slot loaded and defected ground plane structure is presented in this paper to increase the bandwidth. It is found that the impedance bandwidth of a microstrip antenna could be enhanced considerably when a defected ground structure is used .The band width of a truncated rectangular microstrip antenna with H slot is 21.2% whereas after ad...
Here we made an attempt to maximize the gain of microstrip patch antenna. To achieve this we used microstrip circular patch antenna at 5.8 GHz frequency ISM Band Application. Single FSS (frequency selective surface) substrate is used to increase efficiency. Parameters are set accordingly and results of microstrip patch antenna with FSS layer and microstrip patch antenna without substrate later ...
This paper introduces a new geometry of a rectangular microstrip patch antenna that improves the performance of a conventional microstrip patch antenna .This antenna is designed to operate at 5.38 GHz with enhanced bandwidth of 11.15%. For the desired result, a triangular notch is inserted into the patch antenna. The proposed geometry provides improvement in other radiation parameters like gain...
In this paper, the bandwidth of rectangular Microstrip antenna is enhanced by ‘I’ slotted rectangular microstrip patch antenna. In some applications which the increased bandwidth is needed, proposed antenna is one of the alternative solutions. The proposed antenna has been designed at the 2 GHz frequency. The frequency band of proposed antenna is in between (1.64-3.26 GHz) the fractional bandwi...
Modern wireless and mobile communication systems requires antenna which should have light weight, low profile, low cost, and easy to be integrated with RF devices. This demand is completed by microstrip antennas. This paper presents rectangular microstrip patch antenna for WLAN applications designed using IE3D software. The microstrip antenna is designed with dielectric substrate as Rogers RT/d...
This paper presents the increase in bandwidth of a Microstrip Antenna using a simple slotted structure fed by Microstrip line. The main aim of proposed work is to obtain a large bandwidth antenna with reduced size. The proposed microstrip antenna has a wide bandwidth covering the range from 1.806-2.978 GHz. By using simple Microstrip Line feed wide bandwidth of 48.99% has been achieved. The pro...
Despite the many advantages of microstrip patch antennas, they do have some considerable drawbacks. One of the main limitations with patch antennas is their inherently narrowband performance due to its resonant nature. With bandwidth as low as a few percent; broadband applications using conventional patch designs are limited. So for the antenna miniaturization and bandwidth improvement H-shaped...
In these research paper two designs such as rectangular microstrip antenna and concentric equilateral triangular microstrip antenna are presented. The resonant frequency of this antenna is 8 GHz suitable for wireless applications. The antenna is fed by microstrip feeding technique. Design of an antenna using ADS (Advanced Design System), based on MoM (Method of Moments) has been used to analyze...
analysis of aperture-coupled microstrip antennas with a superstrate using space domain closed form greens functions is presented. integral equations are derived from applying the boundary conditions on the radiating patch, across the aperture, and on the microstrip feedline. the computation of space domain greens functions is performed using the closed-form. the solution of the integral equatio...
This paper describes a new microstrip patch antenna which is presented by using a IE3D software .These antenna is named as “Designed and simulation of modified H shaped microstrip patch antenna”. A simulation result has been obtained which states that the microstrip patch antenna possess predictable multi band characteristics. The result shows that the designed antenna can operated in three dif...
