The dielectric resonator antenna (DRA) has received increasing attention in recent years. It has a number of advantages including its small size, light weight, low cost, ease of excitation, and relative wide bandwidth as compared with the patch antenna. Also, it is a volume device that offers the de.....

The dual-polarized patch antennas designed by CityU are compatible with L-shaped probes, which are also invented by CityU. The L-shaped probe is connected to the input port, and part of it is parallel to the patch. The isolation enhancement technique inherent in this invention can reduce the strong .....

Speed sensors are customarily used to detect the speed of power electronic driven motors, but that speed sensors could render the motor drive system unreliable. However, there are very few detection devices other than speed sensors that can generate readings when the motor drives are in a resting mo.....
