Antennas Lab Manual

Our research areas are related to reconfigurable antennas, cognitive radio, W/V antenna design, phased arrays, 3D printed antennas, deployable modular antennas for small satellites, high power microwave antennas, software and FPGA controlled antennas, smart antennas, RF harvesting, high power microwave metamaterial based passive and active devices, and RF photonics.

The lab is equipped with a state of the art anechoic chamber that can be used to perform radiation, gain and polarization measurements up to 100 GHz. The antenna laboratory includes several RF sources, network analyzers, and other measuring devices for testing and evaluating a large variety of microwave and millimeter wave circuits. The lab also provides the capability of building any type of planar and 3 dimensional antenna using its laser-etching milling machine and a number of 3D printers.

Only the most fundamental antennas were chosen for this lab assignment. This allows us to see visually how the most common types of real-world antenna designs function. The following is a glossary of basic antenna concepts. An antenna is a device that.

The COSMIAC facility at UNM has two active satellite tracking and communications ground stations that are operating 24 hours a day tracking and downloading data from active space missions. One of these ground stations is the Mobile CubeSat Command and Control (MC3) ground station. This is one of only five of these ground stations in the US. This advanced system provides the capability to be able to do joint secure communications research while communicating with active spacecraft.

UNM also has a class-10 clean room for satellites and access to several test facilities at Kirtland Air Force Base (KAFB) under the EPA agreement between AFRL and UNM.

The AntennaLab is a unique system designed to be used in two distinct ways; it can be used for teaching and demonstrating common antenna configurations at all levels of study, and as a design tool by those engaged in research and development.

The system operates in conjunction with a PC via a USB interface and is supported by Discovery Interactive Software and NECWIN simulation software. The equipment comprises two towers, one being a low power transmitter, controlled by a frequency synthesizer. The second contains a frequency synthesiser controlled receiver. The antenna to be investigated is mounted on top of the transmitter tower.
