摘要
1Introduction A low-cost slot array antenna is proposed for fifth-generation wireless communication(5G)n260 band applications.The antenna is based on the low-cost printed circuit board(PCB)material FR-4.Empty substrate-integrated waveguide is used to avoid high dielectric loss.High-order-mode cavities are introduced to reduce the complexity of the feeding network.The proposed antenna shows a maximum realized gain of 27 dBi with a radiation efficiency of 72.4%.The measurement and simulation results achieve good agreement.The proposed antenna can be a good candidate for low-cost millimeter-wave(mmWave)wireless communication systems.
