Abstract
An anechoic chamber (100) is provided with a system for introducing wireless communication signals into the anechoic chamber (100) for establishing wireless signaling with equipment under test (122), without interfering with signals from the equipment under test (122) that are to be measured in the anechoic chamber (100). The system comprises a low reflection cross-section cable (236) that extends through the chamber (100) to a weakly radiating small antenna (242, 502) that is positioned proximate the equipment under test (122).
Claims13
An apparatus comprising:
- a radio frequency instrument adapted to operate at a frequency;
- a low reflection cross-section cable comprising a first end coupled to the radio frequency instrument and a second end;
- and
- an antenna coupled to said second end of said low reflection cross-section cable.
1 more element
An apparatus comprising:
- an anechoic chamber for making measurements at, at least one frequency;
- and
- an antenna disposed in said anechoic chamber, wherein said antenna is sized substantially below a size required for resonance at said at least one frequency.
