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 اولDesign of Circular Polarized Microstrip Patch Antenna for L Band
In this paper, we share our experience of designing a circularly polarized square patch antenna at L band. The antenna is designed using a relatively cheap substrate FR-4 with permittivity r = 4:4 and loss tangent tan = 0:02. The antenna has a gain of 5dB. Simulated response shows that the designed antenna has an input impedance(Zin) of 50 approximately. An efficiency of 65% is obtained for ...
متن کاملAnalysis And Design Of Circular Microstrip Patch Antenna At 5.8GHz
Here we made an attempt to maximize the gain of microstrip patch antenna. To achieve this we used microstrip circular patch antenna at 5.8 GHz frequency ISM Band Application. Single FSS (frequency selective surface) substrate is used to increase efficiency. Parameters are set accordingly and results of microstrip patch antenna with FSS layer and microstrip patch antenna without substrate later ...
متن کاملCircular Patch Antenna Design Using Hfss
In this paper Microstrip antenna using semicircular patch is proposed and ANTENNA DESIGN simulated using HFSS software strip feed is used. microstrip antenna design is to increase the bandwidth and gain (1-14). performance analyses using high frequency structure simulator (HFSS) software. I'm starting with the calculation of design parameter using MATLAB. to get better. patch antenna was analyz...
متن کاملDesign consideration of Microstrip Patch Antenna
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...
