Design Of Compact Broadband Microstrip Ring Antenna For High-Speed Data Transmission

Abstract

In modern wireless communication, microstrip antennas are indispensable. This paper focuses on designing 2GHz miniatured width 4mm rectangular ring antenna optimized for enhanced bandwidth performance. Antenna fabricated on FR-4 platform with permittivity of 4.4 and width of 1.6 mm. Compact 4 mm-wide ring structure achieves a wide impedance bandwidth of 1.14 GHz, providing a fractional bandwidth more than 50% of antenna resonating frequency2GHz, making it suitable for high-speed wireless applications such as high-speed data transmission and L band applications. The antenna performance parameters carried out through simulation using high frequency simulation software (HFSS) and measurements are discussed in this paper.
