Abstract: A planar orthomode transducer comprises a substrate integrated resonator, two substrate integrated waveguides connected to the substrate integrated resonator, a dual polarized metal waveguide and a printed circuit board where the substrate integrated resonator and the substrate integrated waveguides are provided, wherein the substrate integrated resonator further comprises a slot aperture in one of metallization layers, and the dual polarized metal waveguide is mounted on a surface of the printed circuit board in an area of the slot aperture of the substrate integrated resonator, wherein the substrate integrated resonator is a nonfundamental orthogonal mode resonator. This enables widening of frequency band of the planar orthomode transducer, reducing of insertion losses, rise of the polarization diversity and providing for a standard dual polarized output waveguide serving for connecting the device with an antenna of various types.

Abstract: A system for forming an ad-hoc network among devices includes a wireless device that utilizes one or more connection protocols; a protocol bridging mechanism operating on one or more communication layers selected from the group of: an application layer, a transport layer, a data link layer, a physical layer and a network layer, wherein the one or more connection protocols connects to other wireless devices through the protocol bridging mechanism; and a controller stored within the wireless device. The system further includes a memory including program instructions executable by the controller that cause the controller to connect to the first nearby wireless device through the first communication protocol; connect to the second nearby wireless device through the second communication protocol; and transmit data between the first nearby wireless device and the second nearby wireless device through the protocol bridging mechanism.
