Abstract: A radiator coupled to an antenna patch disposed along a first end of the radiator, said patch disposed on an insulator. A ground plane is connected to the insulator and a radome is disposed opposite a second end of the radiator. The radome may have a region presenting a convex surface towards the radiator, and the radome has a second region presenting a concave surface towards the radiator. The first end of the conical radiator is the apex of the cone. A ground plane is included and a portion of the ground plane is a planar surface and another portion extends away from the planar portion towards the radome. Also disclosed is a method for forming a radiation pattern by shaping the radome to effectuate a predetermined radiation pattern using localized convex and concave surfaces positioned on the radome at different points in relation to the conical radiator.

Abstract: A microwave system comprises an antenna, antenna feed, a radio transceiver, and appropriate cabling among the aforementioned. Cost, performance and reliability improvements are achieved with further integration of these elements and with design improvements in the antenna feed. One improvement is the integration of the radio transceiver with the antenna feed. This improvement has many benefits including the to elimination of RF cables and connectors. Another improvement is the incorporation of parasitic radiators and sub-reflectors as part to of the antenna feed. The entire antenna, including the feed design is optimized with 3D finite element method (FEM) software and numerical optimization software. Another improvement is the utilization of the digital cable to power the integrated radio transceiver and a center fed parabolic reflector.

Abstract: The present invention offers significant improvements in the performance of a radio receiver operating in an environment with high desired band interference. The present invention comprises a high selectivity RF circuit that is located between the antenna and the radio receiver, and utilizes superheterodyne technology to filter adjacent channel interference in the desired band frequency spectrum. This type of interference is problematic for IEEE 802.11 radio receivers that are implemented with the popular direct conversion radio receiver architectures. The present invention may be utilized in many types of radio receivers.

Abstract: A communication system comprising one or more wireless stations programmed to await for an authorizing signal to initiate wireless communications with a network controller or access point. The network controller maintains identification information in different queues, said queues based upon the wireless station's activity. The wireless station identification information is moved between the different queues in response to wireless station activity. Between polling, each mobile station aggregates data for the next opportunity to transmit. Multi-polling may be employed such that more than a single station is polled at a time. Polling is accomplished by polling one of the more active station along with a less active station. The less active station is unlikely to transmit, so collisions are avoided to a certain degree. If a lesser active station becomes active, it is moved into the more active queue and consequently will be polled more often.
