Abstract (en)
An antenna structure (1) includes a substrate (2) having a ground portion, a radiating electrode (3) disposed adjacent to one end of the substrate (2), and grounding extensions (4) connecting the radiating electrode (3) to the ground portion of the substrate (2). Each of the grounding extensions (4) respectively connected to opposite sides of a grounding end S of the radiating electrode (3) extends from a connection point between the grounding end (S) of the radiating electrode (3) and the grounding extension (4) towards a open end (K) of the radiating electrode (3). An end of each grounding extension (4) is connected to the ground portion of the substrate (2).
