Patent ID: 8564488

Claim:
An antenna, comprising: a first element connected to a first feed point of a hot side; a ground element connected to a second feed point of a ground side; a second element; and a third element; wherein the second element is arranged substantially in parallel with the first element so as to be electromagnetically coupled to the first element, said second element being separate from said first element, wherein the third element is arranged to define a predetermined angle with the first element, with a vertex of the predetermined angle set to a vicinity of the first feed point and the second feed point, said third element being separate from said first element, wherein the first element has a linear shape so as to have an inductive property at a predetermined resonance frequency, wherein the third element has a linear shape so as to have a capacitive property at the predetermined resonance frequency, wherein the first feed point and the second feed point are adjacent to each other, wherein the third element is connected to a ground-side end portion of the second element, and wherein the second element and the third element are not directly connected to the ground element.
