Abstract
A horn antenna configured for use in a radio frequency (RF) anechoic test chamber is provided. The horn antenna includes one or more conductive radiating elements. The horn antenna further includes an electromagnetic interference (EMI) suppressing material covering at least a portion of a surface of the one or more conductive radiating elements such that the EMI suppressing material at least partially suppresses a surface current associated with the surface of the one or more conductive radiating elements during a test operation.

A horn antenna configured for use in a radio frequency (RF) anechoic test chamber, the horn antenna comprising:
- a plurality of conductive radiating elements;
- and
- an electromagnetic interference (EMI) suppressing material covering at least a portion of a surface of the plurality of conductive radiating elements such that the EMI suppressing material at least partially suppresses a surface current associated with the surface of the plurality of conductive radiating elements during a test operation, the EMI suppressing material being attached to the surface of the plurality of conductive radiating elements via an adhesive backing of the ENE suppressing material,
- wherein the EMI suppressing material comprises an elastomeric material comprising silicon rubber, and
- wherein the elastomeric material further comprises ferrite deposited throughout the silicon rubber and metal nanoparticles deposited throughout the silicon rubber.
A system for obtaining data indicative of performance of a test antenna positioned within a RF anechoic test chamber, the system comprising:
- a test antenna disposed within the RF anechoic test chamber;
- and
- a horn antenna disposed within the RF anechoic test chamber, the horn antenna configured to obtain data indicative of performance of the test antenna, the horn antenna comprising:
- a plurality of conductive radiating elements;
- and
- an electromagnetic interference (EMI) suppressing material covering at least a portion of a surface of the plurality of conductive radiating elements of the horn antenna such that the EMI suppressing material at least partially suppresses a surface current associated with the surface of the plurality of conductive radiating elements of the horn antenna when the horn antenna is obtaining the data indicative of performance of the test antenna, the EMI suppressing material being attached to the surface of the plurality of conductive radiating elements via an adhesive backing of the EMI suppressing material,
- wherein the EMI suppressing material comprises an elastomeric material comprising silicon rubber, and
- wherein the elastomeric material further comprises ferrite deposited throughout the silicon rubber and metal nanoparticles deposited throughout the silicon rubber.
An open-boundary horn antenna configured for use in a radio frequency (RF) anechoic test chamber, the open-boundary horn antenna comprising:
- at least two conductive radiating elements;
- and
- an electromagnetic interference (EMI) suppressing material covering at least a portion of a surface of one or more of the at least two conductive radiating elements such that the EMI suppressing material at least partially suppresses a surface current associated with the surface during a test operation, the EMI suppressing material being attached to the surface of the at least two conductive radiating elements via an adhesive backing of the EMI suppressing material,
- wherein the EMI suppressing material comprises an elastomeric material comprising silicon rubber, and
- wherein the elastomeric material further comprises ferrite deposited throughout the silicon rubber and metal nanoparticles deposited throughout the silicon rubber.
