1. An antenna array, comprising:
- a first antenna formed on a first surface of a planar substrate,a second antenna formed on the first surface of the planar substrate displaced from the first antenna in a first direction;
a third antenna formed on the first surface of the planar substrate displaced from the first antenna in a second direction perpendicular to the first direction; and
a fourth antenna formed on the first surface of the planar substrate displaced from the first antenna in both the first and second directions such that the first, second, third, and fourth antennas are disposed in a first 2×
2 grid,wherein each of the first, second, third, and fourth antennas is linearly polarized in the first direction and provides a roughly cardiod radiation pattern in a plane normal to the first direction, a null of the cardiod radiation pattern aligned in the second direction, andwherein the nulls in the cardiod radiation patterns of the first and second antennas face the third and fourth antennas, respectively, and the nulls in the cardiod radiation patterns of the third and fourth antenna face the first and second antennas, respectively.

Abstract
Antenna arrays and access points are disclosed. An antenna array includes first second, third, and fourth antennas formed in a 2×2 grid on a first surface of a planar substrate. Each of the four antennas is linearly polarized in a first direction and provides a roughly cardiod radiation pattern in a plane normal to the first direction. Nulls of the cardiod radiation patterns of the first and second antennas face the third and fourth antennas, respectively, and nulls of the cardiod radiation patterns of the third and fourth antenna face the first and second antennas, respectively.
