This paper describes a comparative study of micro strip patch antenna using line feed & coaxial feed by the optimization of the resonant frequency & radiation resistance of the antenna along with different other antenna parameters. Though the resonant frequency optimization processes of the micro strip patch using line feed & coaxial feed are same, but there is huge difference in radiation...
An attempt has been made to analyze the spectrum utilization across different cellular i.e. GSM, CDMA, UMTS and WiMAX under realistic traffic scenario. The presented simulation study in this paper shows that on an average around 60% of the spectrum remains unutilized for duration of 24 hr. The Dynamic Spectrum Allocation (DSA) approach optimized by Genetic Algorithm (GA) has been applied to enhance...
In the present paper the analysis of gap coupled Rectangular Microstrip patch antenna is carried out by using cavity model. The proposed designed structure provides an impedance bandwidth of nearly 50.6%. The effect of air gap, distance between the parasitic and feed patch and dimensions of fed patch are also studied. The theoretical results are compared with the simulated and Experimental results...
