Description
Summary:This paper presents the design, optimization, and analysis of a tri-band monopole antenna tailored for wireless communication, constructed with a composite FR4 substrate and incorporating split ring resonators (SRRs). The antenna is fabricated on a 19-mm-wide, 31-mm-long FR4 substrate featuring a ground structure integrated with SRRs. Through parameter analysis and optimization, the antenna achieves resonance at 2.3, 4.8, and 7 GHz, catering to diverse wireless communication standards. The use of composite FR4 material ensures enhanced performance. Post-fabrication measurements reveal that the antenna's s11, gain, directivity, and E-plane and H-plane patterns are consistent with simulations. Its compact size, stable radiation patterns, dual-band functionality, excellent impedance matching, and wide bandwidth make it ideal for the industrial, scientific, and medical sectors, as well as other wireless communication applications. This study marks a significant step forward in multi-band antenna technology using composite materials, offering promising solutions for future wireless communication needs.
