Zusammenfassung:An antenna array (1000) includes a horizontal ground layer (40) having a central hole (401), a radiation layer parallel to the ground layer, and a coaxial cable (5) assembled to the ground layer. The cable includes a central conductor (51), an insulated layer (53) coated on the central conductor, and a grounding coat (52) coated on the insulated layer. The central conductor extends through the central hole from a bottom side of the ground layer and keeping insulated from the ground layer. The radiation layer includes a number of radiation units (30) which are coplanar with each other and parallel to the ground layer. Each radiation unit has a nail (301) extending downwardly towards the ground layer. The nail resonates with the central conductor when the antenna array is transmitting or receiving radio frequency signals.
