Integrated Multipath Limiting Ground Based Antenna
Integrated Multipath Limiting Ground Based Antenna
US Patent:
2003020, Nov 6, 2003
Filed:
May 5, 2003
Appl. No.:
10/430959
Inventors:
D. Thornberg - Hurricane UT, US
Dean Thornberg - Salt Lake City UT, US
Dean Thornberg - Salt Lake City UT, US
International Classification:
H01Q021/26, H01Q001/12
US Classification:
343/798000, 343/890000
Abstract:
An integrated dual antenna system for Global Positioning System (GPS), Local Area Augmentation System (LAAS), ground based subsystem surface mounted (pole/tower/platform/other) and coaxially stacked (over and under). The dual antenna and receiver system is specifically designed and tuned to receive only the direct GPS satellite ranging signals while highly rejecting the ground multipath (indirect) signals. The upper antenna is a Right Hand Circularly Polarized (RHCP) omni-directional High Zenith Antenna (HZA) with dual obstruction lights and dual air terminals. The lower antenna is an electrically long vertically polarized omni-directional linear phased array having a very sharp horizon cut off and is a Multipath Limiting Antenna (MLA). When the two antennas (MLA and HZA) are mounted together they become the Integrated Multipath Limiting Antenna (IMLA). Interoperability is assured by high RF isolation between antennas. Both antennas are broad-band and have precisely controlled vertical and horizontal radiation patterns. Together the radiation patterns cover the complete upper hemisphere where satellites are visible.
