Design and simulation of a compact Millimeter-wave (mm-Wave) antenna is presented for next-generation wireless communication systems applications. The proposed antenna is designed on a FR4 substrate with a relative permittivity of 4.4 and a thickness of 1.6 mm, ensuring reduced dielectric loss at higher frequencies. The antenna structure is optimized to operate at 27/34 GHz, a key band for 5G NR applications, while maintaining a compact size of 5 4 1.6 mm3. Simulation studies were carried out using HFSS soft-ware, focusing on achieving wide impedance bandwidth, and stable radiation performance. The designed antenna achieves a reflection coefficient (S11) – 10 dB over the operating frequency range and which is operating under dual bands, offering an impedance bandwidth of 3 GHz (26.43-29.43 GHz) under band 1 and 1.8 GHz (33.82-35.62 GHz) under band 2. The antenna provides a peak gain of 3.6 dB and a good radiation efficiency, making it highly suitable for energy-efficient transmission. The compact geometry and optimized performance make the proposed antenna a promising aspirant for integration into modern 5G cellular networks to provide high speed and low latency data transmission, Internet of Things (IoT) modules, and high-data-rate mm-Wave communication systems. This study highlights the importance of compact antenna structures that achieve high performance without compromising bandwidth, gain, or efficiency, enabling re-liable deployment in 5G, 6G, IoT, V2V, V-I communication and high-speed wireless LANs applications. |
