Analysis of aperture-coupled microstrip antennas with a superstrate using space domain closed form Green's 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 green's functions is performed using the closed-form. The solution of the integral equat...

This paper covers two aspects of microstrip antenna design. The first is the analysis of trapezoidal patch microstrip antenna with V-shaped slot which operate at the centre frequency of 5.5 GHz. The second aspects are the analysis and design of inverted V-shaped slot cut trapezoidal microstrip antenna operates at centre frequency of 4.1 GHz. The simulation has been done through IE3D simulator. ...

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...

Computation of the broadband matching potential of a microstrip antenna requires the wideband lumped equivalent circuit of the antenna. The general topology of the equivalent circuit of rectangular microstrip patch antennas has been used to model the feedpoint impedance of microstrip antennas over a wide frequency band and equivalent circuit parameters are determined using optimization techniqu...

In this work, measurement of the single-molecule magnet (SMM) spin state using a microstrip resonator is considered theoretically. An analysis of the SMM spin dynamics and the interaction between the microstrip and the SMM is presented. The interaction of the SMM with the microstrip causes a shift of the microstrip resonance frequency. An analytic expression for the maximum frequency shift is d...

AbstactThe study of microstrip patch antennas has made great progress in these days. This is mostly due to their versatility in terms of possible geometries that makes them applicable for many dierent situations. Compared with conventional antennas, microstrip patch antennas have more advantages and better prospects like low cost, lighter in weight, low profile, smaller in dimension, low volume...

Abstract: Microstrip antenna is low coast, light weight, and easy to connect with the electric circuit, but it have some drawbacks such as low bandwidth and low gain. In this paper planar microstrip antenna is proposed to enhanced gain and bandwidth. The new design is have modified ground plane and periodic patch. The bandwidth and gain are enhanced, when compared with the traditional rectangul...

One of the advantages of microstrip patches over conventional antennas is their small size. However, there are many present day applications where even these small radiators are too large. Conventional microstrip antennas assume infinitely large ground plane dimensions and thus they are large in size. The size of ground plane is the limitation of antenna characteristics and compactness. In this...

In transmission-reflection method, the microstrip transmission line coated with an organic polymer as an overlay is used to estimate the permittivity of the polymer film. Scattering parameter response of the microstrip line varies as the permittivity of the overlay or its thickness changes. The permittivity is estimated by minimizing the difference between the theoretical (computed from the ana...
