| 20080238782 | High-directivity microstrip antenna - A high-directivity microstrip antenna comprising a dielectric layer with a first surface and a second surface that respectively connects to a metal patch and a ground metal layer, wherein the dielectric layer has a through-hole with a metal element connecting to the first surface and the second surface, and the metal element is positioned at the interior of the through-hole, wherein the two ends of the metal element respectively electrically connects to the metal patch and the ground metal layer for having higher directivity when the antenna is designed in a fixed dimension; also, for saving cost by selecting a dielectric layer with various coefficients. | 10-02-2008 |
| 20080252542 | FULL BAND SLEEVE MONOPOLE ANTENNA WITH EQUIVALENT ELECTRICAL LENGTH - An inductance is coupled to the radiator and a set of inductances is coupled to the sleeve for increasing the resonant electrical lengths of the radiator and the sleeve. A set of impedances is coupled to the sleeve to absorb the reflective power of the radiator for increasing the bandwidth of the antenna. The winding layout of radiator and sleeve and the disposition of passive elements (such as inductance and resistance) allow the sleeve monopole antenna with full band FM radiation to have small size. | 10-16-2008 |
| 20090015503 | MULTI-BEAM-REFLECTOR DISH ANTENNA SYSTEM AND METHOD FOR PRODUCTION THEREOF - A multi-beam-reflector dish antenna system and a method for production thereof are disclosed. Signals from different satellites are simultaneously received using a single compound LNBF module. The multi-beam-reflector dish antenna system includes a reflector with N-th order projected aperture and a single compound LNBF module constituting multiple LNBF units. The reflector is formed by projected aperture cutting and surface distortion of the aperture in accordance with the method of analysis and synthesis. In addition to reflecting signals from satellites, it also generates focused waves sharing similar radiation patterns and horizontal gain with incoming waves on the focal plane to be received by the compound LNBF modules. | 01-15-2009 |
