Abstract:
1. An antenna, comprising: a first conductive plane; a second conductive plane disposed in parallel with the first conductive plane; a feed line applying a high frequency signal between the first conductive plane and the second conductive plane; and at least one shunt which is aligned in the second conductive plane and which comprises a transmission line comprising an open end aligned in a plane above or below the second conductive plane and a conductive via electrically connecting another end of the transmission line to the first conductive plane such that the transmission line forms an open stub, wherein the second conductive plate undergoes a resonance at a frequency f satisfying an inequality of Im(Y(f))≧0 to emit an electromagnetic wave into air in accordance with an equation of: wherein, f: frequency L C Z d: length of the transmission line ∈ c
