ELLIPTICAL MICROSTRIP ANTENNA Resonant Resonant Resonant
above equation the first order formula for the resonant frequency of elliptical microstrip antenna on ferrite sub-strate is found to be (7) The effective permeability of the substrate is expressed as9 = (+ J , where C and D are a function of b/h. Similarly the effective permittivity is expressed as +*(I + 12h/b)-'j2 e, + I &e// = 2 2 which is also a function of b/h. Since b is not uniform throu...
متن کاملDesign of Metamaterial Based Microstrip Antenna With Multiband Frequency Application
This paper introduced a new low cost, compact and robust microstrip antenna based on metamaterial split ring resonator property to replace the existed antenna by small size and multiband Frequency antenna. The proposed antenna is designed with multi rectangular patches and simulated for different frequency. By using the metamaterial property, the bandwidth of the antenna has been improved. The ...
متن کاملNovel Microstrip Antenna Design
A simple, small, compact, low cost, and practical antenna for 2.4 GHz applications is proposed in this paper. A detailed investigation on miniaturized microstrip planar antenna design using a combination of proposed shorted patch and meandering method are presented. All design and simulations are done using Computer Simulation Studio (CST) software. For accuracy reasons, verification has been d...
متن کاملMicrostrip Antenna: Design Aspects
The rapid growth and demand of wireless based applications for commercial and personal communication increases the demand of microstrip antennas with the advantage of being low cost, low profile, small size, capable of being integrated with VLSI design [2], [12]. However microstrip antennas have some inherent limitations i.e. narrow bandwidth, low gain, low efficiency, low power handling, radia...
متن کاملNeural Network Based Estimation of Resonant Frequency of an Equilateral Triangular Microstrip Patch Antenna
Original scientific paper This study proposes an artificial neural network (ANN) model in order to approximate the resonant frequencies of equilateral triangular patch antennas. The neural network structure applied here is trained and tested for both single-layer and double-layer antennas. It is shown upon experiment that the resonant frequencies obtained from the neural network are both more a...
