an infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولDevelopment of A Compact and Low Profile Cavity Backed Slot Antenna Using Microstrip Gap Waveguide Technology
Proof of concept of a cavity backed slot antenna based on inverted microstrip gap waveguide (IMGW) technology is presented. Since the antenna is operating based on the first resonating mode of the cavity, it is more compact compared to the ordinary cavity backed slot antennas in which the second cavity mode is used for radiation. Furthermore, the proposed antenna element introduces lower lo...
متن کاملTriple Band Circular Patch Microstrip Antenna with Superstrate
A novel compact triple band slit cut circular patch antenna with superstrate is proposed; slits on the patch provide additional resonances. The superstrate (cover) of dielectric layer provides protection to printed circuit antenna from environmental hazards due to abnormal weather conditions. The slits add two resonances in the resonance of a circular patch to achieve triple band antenna for mu...
متن کاملDesign and Parametric Analysis of Triangular Microstrip Antenna Loaded with Dielectric Superstrate
ABSTRACT In this paper, the effect of a dielectric superstrate on the gain and resonant frequency of a triangular microstrip antenna has been studied. The proper choice of thickness of superstrate and superstrate layer result insignificant improvement in gain. The improvement in reflection coefficient is also shown. The results obtained shows a shift in resonant frequency by introducing the sup...
متن کاملAnalysis of Aperture Coupled Microstrip Patch Antennas with a Superstrate Using the Space Domain Closed-Form Green`s Functions
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...
