Microstrip antenna slot double-bowtie five-arrays model with coplanar waveguides for 5.8 GHz communication

摘要

Abstract. We have designed, produced and characterized microstrip antenna slot double bowties 5 array using CoudPlanar Waveguide (CPW) as trigger. This new antenna design was developed from a previous model model that has theudfollowing modules such as: a triangular microstrip antenna and microstrip slot double bowtie single array 2 dipoles, auddouble bowtie 3 array 6 dipole for 2.4 GHz wireless communication. The dielectric constant (??r) substrate used was anudFR4 Epoxy with dielectric constant of 4.40 and the electronic etching was done using FeClO3 solution. We conducted audcouple of simulations to obtain the dimensions of the antenna working at the frequency range 4-8 GHz ( C - band) with audmiddle frequency of 5.8 GHz . Adding more arrays enlarged gain, directivity and bandwidth, while the use of CPW wasudto control impedance. We characterize the antenna performance by using the Vector Network Analyzer to obtain ReturnudLoss, Voltage Standing Wave Ratio (VSWR) and bandwidth values of -10.9 dB, 1.7 and 440 MHz, respectively. Theseudresults indicate that the 5.8 GHz antenna is able to be implemented as a part of a communication system.
