Planar Quasi Log Periodic Dipole Antenna for Millimeter Wave 5G Band

This article present the design and measurement of a planar quasi log periodic antenna covering the first millimeter band of 5G (24.25 GHz - 28.4 GHz). The antenna is conceived using HFSS and realized using laser etching on Taconic RF-35 substrate. A modification of the topology is applied to obtain a vialess antenna. The proposed antenna is easier to manufacture than most 5G antenna available with comparable results. The antenna present an measured average gain of 6.85 dB over the first millimetric 5G band.
