Antenna and communication device

摘要

An antenna (100) including a substrate (110), a ground (earth) layer (120), a conductive sheet (130) and a feeding microstrip line (140) is provided. The substrate (110) has an upper surface (112) and a lower surface (114). The ground layer (120) is disposed at the lower surface (114). The conductive sheet (130) is disposed at the substrate (110), substantially perpendicular to the ground layer (120) and electrically connected to the ground layer (120). The feeding microstrip line (140) is electrically connected to the conductive sheet (130). The antenna may be used in a communication device.
