20080295317 | PROCESS FOR MANUFACTURE OF A LOW COST EXTRUDED AND LAMINATED MICROSTRIP ELEMENT ANTENNA - Methods, systems, and apparatuses for automated manufacturing microstrip element antennas is described. The microstrip element antenna comprises a printed circuit layer, a dielectric layer and a ground plane layer. Mass manufacturing process for such microstrip element antennas without any substantial manual assembly process is described. Automation of the manufacturing steps leads to lower production costs, faster production and a higher yield. | 12-04-2008 |
20080297417 | LIGHT WEIGHT RUGGED MICROSTRIP ELEMENT ANTENNA INCORPORATING SKELETON DIELECTRIC SPACER - Methods, systems, and apparatuses for manufacturing light weight microstrip element antennas incorporating a skeleton dielectric spacer instead of a regular solid body dielectric spacer is described. The microstrip element antenna comprises a radiator, a dielectric layer which is in the form of a skeleton rib-caged structure and a ground plane layer. Due to the skeleton rib-caged structure of the dielectric spacer, design flexibility in terms of a non-uniform variation of the effective dielectric constant across various dimensions of the dielectric layer is obtained. Additional advantages of such a dielectric spacer include a wider choice of materials from which the antenna can be made, overall light weight and low production time and machine cost due to lower cooling time of the dielectric. Further, an antenna with a skeleton dielectric spacer further has a better drying characteristics in an event of a water ingress during or post-production. | 12-04-2008 |
