High directivity slot antenna

An antenna, comprising:

• an electrical element;
• an aperture;
• a center channel comprising a front portion corresponding to the aperture and a back portion corresponding to the electrical element;
• and
• columns of radio frequency absorbent material adjacent to respective sides of the center channel, wherein a column of the columns corresponds to a side channel between a first section of the radio frequency absorbent material and a second section of the radio frequency absorbent material, wherein the first section comprises a baffle comprising a metallic element that alters a radio frequency propagation of a first radio wave from the center channel into the second section, wherein the first radio wave has been received through the aperture and misaligned from a direct path between a source of the first radio wave and the electrical element, and wherein the second section absorbs the first radio wave.

A system, comprising:

• a processor;
• and
• a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
• receiving, via a central chamber between columns of segments of an antenna, a first electromagnetic signal outside of a direct path from a source of the first electromagnetic signal to an electrical element of the antenna, wherein the segments comprise a radio frequency absorbent material;
• and
• absorbing the first electromagnetic signal by a segment of the segments that is adjacent to a baffle that alters a radio frequency propagation of the first electromagnetic signal.
