20120280875 | SPHERICAL PERTURBATION OF AN ARRAY ANTENNA - The present invention provides a high-performance and small sized helical antenna element and array thereof for use in an aircraft communication system or the like, where stringent spatial restrictions and gain requirements generally apply. The performance of the array is enhanced by increasing the lateral distances between the antenna elements over a portion of the elements where the windings thereof have high current amplitude. The sweeping envelope of the array is maintained small by recovering the initial distancing over a portion of the elements where the windings thereof have low current amplitude. | 11-08-2012 |
20120268334 | OPTIMAL LOADING FOR INCREASED GAIN IN AN ARRAY ANTENNA - The present invention provides a high-performance helical antenna element and array thereof for use in an aircraft communication system or the like, where stringent spatial restrictions and gain requirements generally apply. The performance of the array is enhanced by connecting conductive plates to the windings of the antenna elements at the terminal ends thereof such that the conductive plates are offset from the axes of the antenna elements and toward the center of the array. | 10-25-2012 |
20120256797 | INCREASED GAIN IN AN ARRAY ANTENNA THROUGH OPTIMAL SUSPENSION OF PIECE-WISE LINEAR CONDUCTORS - The present invention provides a high-performance and lightweight helical antenna element and array thereof for use in an aircraft communication system or the like, where stringent spatial restrictions and gain requirements generally apply. The RF performance of the array is enhanced by using ribs and sleeves to reduce the dielectric volume of the support structures of the antenna elements, and by providing apertures within the sleeves of the support structures and between the ribs thereof. | 10-11-2012 |
