Microstrip patch antennas became very popular in mobile and radio wireless communication, due to ease of their analysis, fabrication, and attractive radiation characteristics. The use of Microstrip antenna in wireless communication found advantageous compared to other types of antenna due to their low fabrication cost, small size, supporting character to linear as well as circular polarization,...

In this paper, I have explored a significant concept for the miniaturization of microstrip patch antenna configuration by using the double negative (DNG) left-handed Metamaterials, which have dielectric permittivity and magnetic permeability both negative, simultaneously. It is achieved through the concept of phase-compensation by thin slab consist of the double positive (DPS) material, which h...

In this Letter, a dumbbell-shaped patch loaded slotline(PLS) is proposed. Like the conventional defected ground structure(DGS) for a microstrip line, we show that the proposed PLS can provide a wide bandstop characteristic in some frequency bands with only one or small number of unit cells. Also, the equivalent circuit model for a unit section is derived from the analysis of the field distribut...

A compact size low profile microstrip-fed crossed monopole antenna for ultra wideband communication is presented. The impedance bandwidth of a microstrip crossed monopole antenna has increased with a suitable dimension of ground plane and rectangular patch. The aim of this paper is to improved bandwidth and return loss of a Crossed Monopole Microstrip patch antenna and study the effect of anten...

In recent years, great interest was focused on microstrip antennas for their small and good performance. With the continuous growth of wireless communication communication equipment, there are higher and higher demands feed single layer compact rectangular microstrip antenna application is proposed in this paper. Two L slits are introduced at edge of the patch to reduce the resonant frequency. ...

A decrease in physical size and multiband ability are essential requirements for antenna incoming wireless devices.The antenna based on Sierpinski fractal antenna theory. Design & simulation of fractal triangle microstrip patch antenna done by using IE3D software of Zeland. In this paper, a special technique is proposed to design a new patch antenna, shapes is equilateral triangular fed by a 50...

Abstract: An inset feed microstrip patch antenna is designed to increase the bandwidth and return loss. RT-Duriod with dielectric constant of 4.4 is used as a substrate for the proposed antenna. RT-Duriod is a having a lowest dielectric constant and can reduce the dielectric losses associated with microstrip patch antenna. This antenna is useful for 2.4 GHz frequency, which comes under ISM (Ind...

In this paper a novel design of small sized, low profile coaxial fed microstrip patch antenna is proposed for terrestrial DTV signal reception applications in the UHF band frequency range of 540-890MHz. Designed model was spiral slot microstrip patch antenna using shorting plates for size reduction. Different parameters like return loss, VSWR, gain along θ, Ø directions, radiation pattern in 2D...

A new reduced size single probe fed microstrip patch antenna with irregular slits has been presented to be used as a receiving antenna for Global Positioning Systems (GPS) integrated with cellular handheld mobile wireless systems. The proposed design is based on the nearly square microstrip patch antenna with two pairs of orthogonal slits cut from the edge. It has been found that this antenna o...

In this paper, microstrip patch antennas with six different shapes i. e. rectangular, circular, square, elliptical, pentagonal and hexagonal are implemented using Ansoft HFSS version 13. 0. 0 software. Antennas are designed on Rogers RT/duroid 5880 material with dielectric constant 2. 2 and thickness 3. 2 mm. The different performance parameters such as return loss, gain and bandwidth of these ...
