Abstract

A printed millimeter wave dipole antenna and techniques for designing such an antenna are disclosed. In one embodiment, the dipole antenna comprises: a signal wing and at least one ground wing for propagating signals in a millimeter wave band; and an unbalanced feeding structure directly coupled to the signal wing. The unbalanced feeding structure is boarded by a plurality of escorting vias to ensure equipotential grounds.

First claim

What is claimed is:

1 . A printed millimeter wave dipole antenna, comprising:
a first dipole wing and a second dipole wing for propagating signals in a millimeter wave band; and a balanced feeding structure construed to include a first feed stripline connected to the first dipole wing and the second feed stripline connected to the second dipole wing.

2 . The printed millimeter wave dipole antenna of claim 1 , wherein a portion of a ground layer extends out over the first and second feed striplines, wherein the ground layer is of a substrate on which the millimeter wave dipole antenna is printed.

3 . The printed millimeter wave dipole antenna of claim 1 , wherein the first and second feed striplines are tapered to match to differential feed lines of the dipole antenna.

4 . The printed millimeter wave dipole antenna of claim 1 , wherein at least one signal director is placed in front of the first and second wings.

5 . The printed millimeter wave dipole antenna of claim 1 , wherein the dipole antenna acts as a Yagi-Uda driven element.

6 . The printed millimeter wave dipole antenna of claim 1 , wherein the dipole antenna acts as a power combiner.

7 . The printed millimeter wave dipole antenna of claim 1 , wherein the millimeter wave dipole antenna is printed on at least a middle layer of a substrate.

8 . The printed millimeter wave dipole antenna of claim 1 , wherein the millimeter wave band is at least the 60 GHz frequency band.

9 . A printed millimeter wave dipole antenna, comprising:
a first dipole wing and a second dipole wing for propagating signals in a millimeter wave band; and a balanced feeding structure construed to include a feed stripline and a balun, wherein the dipole antenna is printed on a metal layer between ground layers of a substrate.

10 . The printed millimeter wave dipole antenna of claim 9 , wherein the ground layers are separated by a ground via a wall.

11 . The printed millimeter wave dipole antenna of claim 9 , wherein the distance from the first and second dipole wings to the ground via wall is a quarter of a wavelength.

12 . The printed millimeter wave dipole antenna of claim 9 , wherein the millimeter wave band is at least the 60 GHz frequency band.
