An antenna range is a facility that is used to test the radiation characteristics of an antenna.  The entire measurement facility consists of six parts:

1. 1.The Space
   

2. 2.Source and test Antennas (TX and RX in diagram)
   

3. 3.Antenna Positioners (blue and red boxes)
   

4. 4.A transmitter (purple boxes)
   

5. 5.A receiving System (orange box)
   

6. 6.Data display and recording equipment (grey box)

There are many different types of antenna ranges varying from far field outdoor ranges to near field ranges.  The design team focussed specifically on a small indoor semi-anechoic range.  This type of range is an indoor range and is set up in a room surrounded by anechoic material.  Anechoic material is an absorbing material that is designed to absorb incident RF radiation.  This material is expensive, so the team decided to set up a semi-anechoic backdrop to the receive antenna.  First a wall frame set at an angle was made. Then a layer of anechoic material was attached in order to reduce the RF reflections.

This set up allowed for enough RF field to be absorbed so accurate results can be found.  Also this set up allows for some mobility of the antenna range.
