Diseño e implementación de una antena microstrip de banda ancha para la frecuencia de 2.4 GHz mediante el algoritmo Slot-Loaded.

Abstract

The main objective of the present work was the design and construction of a broadband microstrip antenna that works at the frequency of 2.4 GHz using the SLOT-LOADED algorithm, which responds to the technological development that looks for smaller and devices with good performance. The SLOT´LOADED algorithm was analyzed in order to obtain the basic design of the antenna and its dimensions. In the ANSOFT HFSS program the design of all antenna components including the coaxial feed section was optimized, the microstrip antenna measurements were optimized until it was able to work at the desired frequency with optimum operating parameters, such as the frequency of the resonance, the bandwidth, the gain, parameter S, VSWR, radiation pattern, which were analyzed one by one. In the simulation of the final design, a bandwidth of 340 MHz with center frequency of 2.4 GHz was obtained, which initially meets the expectations of the simulation. After the simulation of the microstrip antenna was made using materials of easy adquisition and that comply with the design characteristics, the implementation of the antenna was completed with the respective tests, using a signal generator and a spectrum analyzer of brand ANRITSU facilitated by the School of Electronics Telecomunications and Networks. Through the measurements, it was possible to obtain values of the interpretation of results was performed based on graphs made in the MATLAB program. The results of the tests with measuring equipment were satisfactory sonce a 450 MHz bandwidth was obtained which was verifield by the measurement of the power level received. Further analysis of results is recommended by means of measurements in interference-free environments and using other types of equipment containing more measurement parameters.
