Abstract
Official abstract text for this publication.
Disclosed is an antenna array, including: a first antenna; a second antenna; and a dielectric substance, of which a height is determined based on a distance between the first and second antennas and forms of beam patterns of the first and second antennas. According to the antenna array according to the exemplary embodiments of the present invention, it is possible to decrease coupling between the antennas.
First claim
Opening claim text (preview).
What is claimed is: 1 . An antenna array, comprising: a first antenna; a second antenna; and a dielectric substance, of which a height is determined based on a distance between the first and second antennas and forms of beam patterns of the first and second antennas. 2 . The antenna array of claim 1 , wherein the beam patterns of the first and second antennas comprise beam widths of main lobes. 3 . The antenna array of claim 2 , wherein the beam widths of the main lobes of the first and second antennas are the same as each other. 4 . The antenna array of claim 3 , wherein when the distance between the first and second antennas is smaller than two times the beam widths of the main lobes of the first and second antennas, the height of the dielectric substance is determined by lengths from distal ends of the first and second antennas to a point defining the beam width. 5 . The antenna array of claim 3 , wherein when the distance between the first and second antennas is equal to or larger than two times the beam widths of the main lobes of the first and second antennas, the height of the dielectric substance is determined based on lengths of side lobes of the first and second antennas. 6 . The antenna array of claim 5 , wherein the lengths of the side lobes of the first and second antennas are the same as each other. 7 . The antenna array of claim 1 , wherein the dielectric substance is disposed between the first antenna and the second antenna. 8 . The antenna array of claim 1 , wherein the first antenna and the second antenna are directional antennas. 9 . An antenna array, comprising: a first antenna; a second antenna; and a dielectric substance disposed between the first and second antennas, and extended from distal ends of the first and second antennas by a length determined based on a distance between the first and second antennas and beam widths of main lobes of the first and second antennas. 10 . The antenna array of claim 9 , wherein the beam widths of the main lobes of the first and second antennas are the same as each other. 11 . The antenna array of claim 10 , wherein when the distance between the first and second antennas is smaller than two times the beam widths of the main lobes of the first and second antennas, the dielectric substance is extended from the distal ends of the first and second antennas by the lengths from the distal ends of the first and second antennas to the point defining the beam width. 12 . The antenna array of claim 10 , wherein when the distance between the first and second antennas is equal to or larger than two times the beam widths of the main lobes of the first and second antennas, the dielectric substance is extended from the distal ends of the first and second antennas by lengths of side lobes of the first and second antennas. 13 . The antenna array of claim 12 , wherein the lengths of the side lobes of the first and second antennas are the same as each other. 14 . The antenna array of claim 9 , wherein the first antenna and the second antenna are directional antennas.
