The compact variation of equilateral triangular microstrip antenna, a shorted 600 Sectoral microstrip antenna is discussed. The proximity fed shorted 600 Sectoral microstrip antenna is proposed which gives simulated and measured BW of more than 700 MHz (>60%). To increase the bandwidth and gain, gap-coupled configuration two Shorted 600 Sectoral patches is proposed. It yields simulated and meas...

The microstrip patch is one of the most preferred antenna structures for ofordable and compact design for wireless system and RF applications. This paper compares the rectangular patch antenna and equilateral triangular microstrip antenna in terms of their return losses and radiation pattern. For the comparative study the Ansoft HFSS V11 is used. Keywords— rectangular micro strip antenna, retur...

Microstrip filters are widely used in microwave circuit, This paper briefly describes the design principle of microstrip band stop filters. This paper presents novel millimeter wave filter structures by creation of some slots on the strip. This paper presents the design and simulation of a narrow band stop filter using microstrip which is designed to have a central frequency of 1.273 GHz which ...

This paper presents a robust approach for calculating spatial-domain Green’s functions on the interface or close to the interface of planar multilayered microstrip structures with lossless or lossy dielectric materials for a wide range of frequencies and layer thicknesses. We compute the mixed potential Green’s functions for distance for 200 points from 0.1 to 10 wavelengths. The CPU is less th...

This article proposes, single feed compact slotted patch antenna. It can be seen that bandwidth of Microstrip antenna is increased up to great extant by cutting two equal slots which are same as π structure added with rectangular slots. In some applications in which the increased bandwidth is needed, designed antenna is one of the alternative solutions. The proposed antenna operates in frequenc...

The design of a single-band singly-layered reflectarray fed by circularly polarized 2x2 microstrip patch antenna array with corporate feeding to be used in K-band (18.7–19.2 GHz) is proposed this paper. It demonstrated simulations and measurements that the axial ratio bandwidth performance depends strongly on polarization purity feeder. Simulated measured results revealed complete exhibits good...

In a dual-plane compact electromagnetic band-gap (CEBG) microstrip structure, patches are etched periodically in the ground plane to prohibit the propagation of electromagnetic waves in certain frequency bands so as to provide filtering functionality. However, the existence of the etched patches in the ground plane becomes a natural concern for the reason that these structures might be more pro...

An accurate and efficient method was developed for computing the resonant frequencies of microstrip resonators. The formulation of the problem was carried out rigorously using the fullwave analysis rather than the quasi-static approximation. The characteristic equation was derived using Galerkin’s method applied in the Fourier transform domain. The accuracy of the method has been proven by comp...
