The following is an abstract of the paper, the mirror image design parameters and effective results for an antenna with a rectangular microstrip overlay using IE3D software is described that outcomes of the simulations and designs are displayed. The probe feed approach was used to generate the microstrip patch pattern. Such patch antennas have been investigated due to their large bandwidth and gain. This antenna is fabricated on an FR-4 epoxy substrate. This antenna’s performance and results are also matched to a standard rectangular patch antenna. Variables are utilized to improve the antenna’s simulation results are as position, space, length, and width of different mirror images T and I shaped antenna slots. The measured results from the simulated design show that the designed construction resonates at various closely separated frequencies that are within the frequency band allotment for wireless applications. At resonance frequencies of 2GHz to 3GHz, the bandwidth and return loss are significantly enhanced.

This is the first report on novel mushroom-type electromagnetic band gap (EBG) structures, consisting of fractal periodic elements, used for enhancing the gain of microstrip patch antennas. Using CST Microwave studio the performance of rectangular patch antenna has been examined on proposed fractal EBG substrates. It is found that fractal EBGs are more effective in suppressing surface wave thus resulting in higher gain. The gain of rectangular patch has been improved from 6.88 to 10.67 dBi. The proposed fractal EBG will open new avenues for the design and development of variety of high-frequency components and devices with enhanced performance.


This paper present the brief view to design of a microstrip rectangular patch antenna. Microstrip patch antennas are used because of configuration such as low profile, conformal, light weight, and easy fabrication. The linear polarization and circularly polarization of microstrip patch antennas have attracted more attention recently. These antennas are significant due to their ability to improve the benefits of microwave imaging application. The Federal Communication Commission (FCC) has approved the frequency limit for narrowband and wideband antenna. One of the advantage of the narrow band technology is the design of feasible compact conformal antennas. Therefore a compact miniaturized microstrip rectangular patch antenna has been proposed to design for microwave imaging application. The miniaturization of microstrip patch antenna has been done to obtain the better narrow bandwidth, return loss and Voltage Standing Wave Ratio (VSWR). Ultra Wide Band (UWB) is achieved by using certain techniques which is used for expansion of bandwidth. The rectangular patch antenna with a 50Ωmicrostrip feed is fabricated on the FR4 substrate.

Author have studied various design techniques to design multiband patch antenna. Proximity coupled technique was found more suitable and efficient to design a multiband antenna. This proposed designed antenna is able to operate in two distinguished frequency that means proposed antenna is a dual band antenna with large bandwidth and high directivity. This proposed design contains a defected ground, a rectangular patch and a meandered feed, which is designed to connect a SMA connector. Designed antenna is a 3 layer device having higher radiation intensity at 1.96 and 2.6GHz.

In this paper, we resolve two issues of microstrip antennas, which are miniaturization and efficiency behavior. For  that, a rectangular patch antenna with 16×18×1.6 mm3 dimensions with dual-band characteristics, was designed, fabricated and characterized.  In order to improve the problem of narrow bandwidth in  microstrip antennas, we implement in this study the slot  technique, allowing us to achieve our purpose. This technique,  lead to a good reflection coefficient and VSWR. The  characteristics of the fabricated antenna were measured and  analyzed by Vector Network Analyzer. The results show two  resonance frequencies that define two bandwidths defined by a  return loss less than -10 dB and are respectively; 7.47 GHz at a  frequency of 400 MHz, and 11.01 GHz at a frequency of 790  MHz. Also, the obtained gain has a good value and it’s very  remarkable according to the small size of the structure, with  a peak value of 6.1 dB at 12.5 GHz.  The small size and good characteristics enlarged the applications  domains of our structure, from telecommunications and  especially Radar, satellite communications to medical and  wireless applications.


In this paper, a microstrip rectangular patch antenna (MRPA) with defect in ground in terms of reduction in dimension has been simulated, tested and analyze for multiband wireless applications. The defect (reduction in size) has been introduced to study the grounding effect in patch antennas for four configuration namely full ground, quarter ground, half ground right and half ground left antennas. After the comparison of simulated results of all four structures, the proposed better performed antenna with 23.815mm x 41 mm x 1.6mm dimension has been fabricated and tested. It operates in wide bandwidth from 2.5 GHz to 9.2 GHz suited for S band requirements which covers many wireless applications like Wifi, WLAN and WiMax. The experiment results shows that the proposed antenna has lower group delay and loss, ideal VSWR less than 1.5, impedance nearer to ideal 50 ohm and gain of 4.3 dBi. There is very good agreement between the simulated and tested results.


In modern world, communication systems requires development of low cost, minimal weight, and low profile antennas which are capable of maintaining high performance over wide range of frequencies. Patch antenna is one such antenna which fulfills the demands of current communication systems. The widely used microstrip patch antennas are rectangular patch antennas. This paper presenting the application of binary coded Genetic Algorithm (BGA) which is applied to the rectangular patch microstrip antenna with uniform linear arrays. The fitness function of GA is maximum reduction in peak side lobe level of the radiation pattern of the antenna with maximum reduction in the side lobe level and also achieved the minimum possible null to null beam width, the resultant radiation patterns for both before GA and after GA of microstrip array are compared. The radiation patterns are presented for 20,50,100 number of elements. All the simulated results are obtained by using MATLAB software.

This study describes the design of dual rectangular microstrip patch antenna for Wi-Fi and WiMAX wireless communication applications. In this work, the technique of design array patch antennas was used in order to improve the physical antenna characteristics for Wi-Fi and WiMAX device. As a result, the proposed technique causes to increase the gain and directivity of the antenna.
