The research presents the design and analysis of a compact clover-shaped antenna optimized for millimeter-wave (mmWave) 5G applications operating within the 24–28 GHz frequency band. The proposed antenna features a compact footprint of 10 mm × 10 mm and is fabricated on a Rogers RT/Duroid 5880 substrate, known for its excellent dielectric properties suitable for high-frequency applications. The feed-line width is optimized to 2.20 mm for proper impedance matching, resulting in a return loss (S11) of less than -10 dB and a Voltage Standing Wave Ratio (VSWR) in the range of 1 to 2, ensuring efficient power transfer. The antenna achieves a peak gain between 5 to 7 dBi and supports a 4 GHz bandwidth, making it well-suited for wideband 5G communications.
