Patent Images
1. A wireless communication apparatus comprising:
- a handheld, rectangular housing having a front face, a back face, and four sides; and
a linear array of volumetric antenna elements disposed within the housing along each of the four sides; and
wherein the volumetric elements each circumscribe a three-dimensional volume and the volumetric antenna elements each further comprise;
a first conductive patch surface aligned in parallel to a selected one of the four sides,a second conductive patch surface aligned in parallel to the front face, anda third conductive patch surface aligned in parallel to the back face,the second patch surface and third patch surface being symmetric such that the second patch surface has a same rectangular shape and dimension as the third patch surface.

Abstract
Antenna arrays that provide directive radiation over multiple frequencies, multiple polarizations, and/or operate in modes that reduce unnecessary radiation into a nearby human body. The arrays are particularly adapted for use with handheld wireless devices, such as smartphones, tablets, and cellular phones.
