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

Abstract

We have designed, produced and characterized microstrip antenna slot double bowties 5 array using Co Planar Waveguide (CPW) as trigger. This new antenna design was developed from a previous model model that has the following modules such as: a triangular microstrip antenna and microstrip slot double bowtie single array 2 dipoles, a double bowtie 3 array 6 dipole for 2.4 GHz wireless communication. The dielectric constant (εr) substrate used was an FR4 Epoxy with dielectric constant of 4.40 and the electronic etching was done using FeClO3 solution. We conducted a couple of simulations to obtain the dimensions of the antenna working at the frequency range 4-8 GHz (C - band) with a middle frequency of 5.8 GHz. Adding more arrays enlarged gain, directivity and bandwidth, while the use of CPW was to control impedance. We characterize the antenna performance by using the Vector Network Analyzer to obtain Return Loss, Voltage Standing Wave Ratio (VSWR) and bandwidth values of −10.9 dB, 1.7 and 440 MHz, respectively. These results indicate that the 5.8 GHz antenna is able to be implemented as a part of a communication system.
