A Wideband Bowtie Antenna Fed with CPW for 5G mmWave Applications

In recent years, millimeter wave (mmWave) antennas have garnered considerable attention, especially in the realm of 5G applications. This study introduces a compact wideband planar bowtie antenna designed specifically for 5G mmWave communications. The antenna consists of a pair of bowtie patches that are fed by a grounded co-planar waveguide (GCPW). Notably, this design requires only two thin substrate layers. Simulation results demonstrate that the antenna offers a broad bandwidth of 33.35% (34.62–47.96 GHz) and achieves a realized gain of 6.25 dBi at 40 GHz.
