The paper presents a broadband microstrip patch antenna for wireless communication. In its most basic form, a microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side. The patch is generally made of conducting material such as copper or gold and can take any possible shape. A rectangular patch is used as the main rad...

In this present work, Rectangular Microstrip Patch antenna loaded with symmetrically cut H and hexagonal shaped metamaterial (MTM) is proposed for better improvement in the impedance bandwidth and reduction in the return loss at operating frequency 1.794 GHz. The proposed antenna is designed at a height 3.2 mm from the ground plane. At 1.794 GHz, the bandwidth is increased up to 27 MHz in compa...

The dual band microstrip antenna is realized by placing the open circuit stub or by cutting the slot inside the patch. The compact microstrip antenna is realized by placing the shorting post or plate along the zero field line at the fundamental mode of the patch. In this paper, a compact variation of equilateral triangular microstrip antenna, a shorted 600 sectoral microstrip antenna is discuss...

Many kinds of microstrip array antennas have been developed in the millimeter-wave band. In order to avoid feeding loss and the decrease of antenna gain by beam shift due to frequency changes, center-fed array antennas are advantageous. In this case, the element spacing around the feeding circuit of the transition from the waveguide to two microstrip lines is larger than one wavelength. Therefo...

a new multiple c- slotted microstrip patch antenna is proposed.  a patch antenna is a wide-beam narrowband antenna. microstrip patch antenna consist of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. the patch can be designed in any possible shape and normally made by conducting material copper or gold. this paper presents design of a c- slotted ...

This article describes the design of single microstrip rectangular patch antenna and 1x1 microstrip rectangular patch antenna arrays operating at 2.4 GHz. Simulation result shows that 5.199 dB and 7.84 dB gain can achieved at frequency 2.4 GHz. Also simulation result show that the return loss is 18.809 at 2.360 GHz in 1x1 microstrip antenna array and current distribution and 3D radiation patter...

Abstract—A model for the two-dimensional analysis of microstrip lines, named Rigorously Coupled Multi-conductor Strip (RCMS) is introduced. In this model, the width of the strip of a microstrip line is subdivided into a large number of rigorously coupled narrow strips. So, a microstrip line can be considered as a coupled multi-conductor transmission line. Determination of the capacitance and in...

A single layer, single feed compact slotted patch antenna is thoroughly simulated in this paper. Resonant f requency has been reduced drastically by cutting three equal slots which are same hexagonal structure at the upper right, upper left and lower left corner from the conventional microstrip patch antenna. It is shown that the simulated results are in acceptable agreement. More importantly, ...

The aim of this investigation is to improve the performance of a basic microstrip antenna array using a tree structure patch supplied by electromagnetic coupling. The developed network which contains two subnets, a distribution subnet and a scanning subnet, is considered as a first step to design an adaptive microstrip antenna for UMTS use. The patch distribution structure used in this experime...

We present a new computer-aided modeling methodology to develop physicsbased models for passive components. We coherently integrate full-wave electromagnetic simulators, artificial neural networks, multivariable rational functions, dimensional analysis, and frequency mapping to establish broadband models. We consider both frequency-independent and frequency-dependent empirical models. Frequency...
