Laboratoire d'antennes FEEDBACK - 57-200

Description * 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.

Features * Unique integration of hardware and software * Simulates, models and tests real antennas * Hardware modelling between 1200 and 1800MHz * NEC-2 based simulations * PC measurement and results * Rapid graphic display of antenna characteristics * Bench-top operation * Low, safe power output * USB interface

Curriculum Coverage * Familiarisation * The Diplole in free space * Effects of the surroundings * Dual sources * Gain, directivity and aperture * Ground reflections * The monopole * Phased monopoles * Resonance, impedance and standing waves * Return loss and VSWR measurements * Parasitic elements * Multi-element parasitic arrays * Stacked and bayed arrays * The log periodic antenna * The horn antenna * The dish antenna * Projects
