The circularly polarized array antenna comprises: a plurality of circularly polarized antennas with phase shift mechanism for receiving circularly polarized signals and transmitting the circularly polarized signals; a plurality of power lines which differ from each other in length and are coupled to the circularly polarized antennas respectively; and a power divider coupled...

A built-in antenna module of a wireless communication terminal is provided. In the antenna module, a substrate is disposed inside a terminal body and has a plurality of electronic parts mounted therein. At least one radiator rib is integrally extended from the terminal body along a predetermined pattern in accordance with properties of the antenna. A radiator line is made of a conductive elastomer which is dispensed and coated onto an upper end of the radiator rib. The radiator line has an end e...

A direct-illumination backlight apparatus using LEDs includes a flat reflective plate, an LED light source, a transparent plate, a scattering pattern, and a light guide. The light guide serves to introduce a partial light from an LED light source at such an angle that the partial light is trapped inside the transparent plate, and the scattering pattern serves to scatter the trapped light beam at a position directly above the LED light source so that the scattered light beam escapes out of the tr...

In a pump system for supplying powder, in particular coating powder, to a powder coating apparatus, time controller is used to introduce compressed gas into a metering chamber as a function of the predetermined delay time elapsed since a predetermined operational point for the purpose of expelling a quantity of powder that was introduced into the metering chamber until the end of the time delay.
