ANTENNA SYSTEM FOR PROVIDING COVERAGE FROM A HIGH-ALTITUDE PLATFORM

摘要

Aspects of the disclosure provide an antenna system (218) for a high -altitude platform (HAP) (114). The antenna system (218) may include a central panel (310, 410, 510) including a first set of antenna elements (450, 452, 454, 456, 458, 550, 552, 554, 556, 558). The antenna system (218) may also include a plurality of auxiliary panels (320, 322, 324, 326, 420-431, 520, 522-525) arranged around the central panel and at an angular offset from the central panel (310, 410, 510). Each auxiliary panel of the set of auxiliary panels may include a second plurality of antenna elements (440, 442, 444, 446, 448, 540, 542, 544, 546). The first plurality of antenna elements (450, 452, 454, 456, 458, 550, 552, 554, 556, 558) may be configured to provide network coverage within a first area (610) having a first radius and each of the second sets of antenna elements (450, 452, 454, 456, 458, 550, 552, 554, 556, 558) are configured to provide network coverage within a second area (620) beyond the first radius.
