Initially, a comparative analysis of circular patch microstrip antennas designed to operate at 2.4 GHz is carried out, considering feeding techniques such as coaxial probe, inset microstrip line, and quarter-wave transformer. The analyses are performed through numerical simulations using the Ansys HFSS software, evaluating parameters such as return loss, voltage standing wave ratio (VSWR), input impedance, and bandwidth. The results indicate significant differences among the analyzed techniques, with the inset microstrip line feed presenting the best performance, achieving return loss below −20 dB at the design frequency and VSWR values close to 1.2, while the other techniques showed higher sensitivity to geometric variations and resonance frequency shifts. Subsequently, the design and experimental validation of a microstrip patch antenna with a bioinspired geometry based on the Monstera deliciosa leaf are presented. The antenna was developed on an FR-4 substrate and exhibited dual-band behavior, with resonance frequencies around 2.57 GHz and 3.09 GHz, as well as good impedance matching to a 50 Ω feed line. The antennas were fabricated using laser cutting and chemical etching processes, and the experimental characterization was performed using the portable vector network analyzer LiteVNA 64, allowing direct comparison between simulated and measured results. The obtained results demonstrate the feasibility of the proposed methodologies for both impedance matching analysis and the development of bioinspired microstrip antennas, highlighting their applicability in academic and research-oriented projectsAcesso AbertoAntenas de microfitaPatch circularTécnicas de alimentaçãoCasamento de impedânciaLiteVNA-64Microstrip antennasCircular patchFeeding techniquesImpedance matchingCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOES::TEORIA ELETROMAGNETICA, MICROONDAS, PROPAGACAO DE ONDAS, ANTENASTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
