In this contribution, a fan-beam antenna employing a non-parasitic reflector in a grounded manner is introduced. A fan-beam antenna is achieved by 13 elements conventional planar monopole array antenna. This concept is performed by combining planar monopole antenna as an array and non-parasitic L-shaped reflector. This array element has an Omnidirectional pattern and these characteristics are allowed to control the antenna H-plane 3 dB beam-widths for the desired angle by grounded reflector shape. The antenna input impedance matching bandwidth is approximately 1550–2550 MHz when simulated. The antenna has broad band input impedance band width, good radiation patterns and proper peak gains in DECT, 3G and 4G bands. This type of antenna can be constructed easily, cheaply as well as being light weight for installation.

In order to get the rotor fault characteristic component in stator current, an advanced correlation algorithm is presented in this paper. Because of faster and multi-channel ADC subsystem, S3C2410 ARM is chosen as the core of stator current acquisition to meet the need of spectrum analysis. By programming on LabWindows/CVI — a virtual instrument development tool, the fault information can be separated from stator current signal. Then make the spectrum analysis to the residual signal, the broken bar fault can be diagnosed easily. The results of experiment indicate that a reliable and portable system can be realized to meet the purpose of testing and diagnosing the faults of induction motors in-situation, and method is feasible and effective.
