Patent number: 9680224Abstract: The multiple polarization loop antenna includes a circularly polarized loop antenna, which may utilize a loop electrical conductor and two signal feedpoints along the loop electrical conductor separated by one quarter of the length of the loop circumference for a signal feedpoint phase angle input difference of 90 degrees. Each of the signal feedpoints may include a loop discontinuity, so that at least one signal source coupled thereto provides circular polarization from the loop electrical conductor. The circularly polarized loop antenna provides an increase in gain and decrease in size relative to the dipole turnstile. It can provide two orthogonal polarizations from two isolated ports, and the polarizations may be dual linear or dual circular.Type: GrantFiled: August 21, 2014Date of Patent: June 13, 2017Assignee: HARRIS CORPORATIONInventors: Francis Eugene Parsche, Dennis Lee Tebbe

Patent number: 8164529Abstract: A loop antenna may include first and second electrical conductors arranged to define a circular shape with first and second spaced apart gaps therein. Opposing portions of the first and second electrical conductors at the first gap may define a signal feedpoint, and opposing portions of the first and second electrical conductors at the second gap may define an impedance tuning feature. The second gap may be circumferentially spaced from the first gap less than ninety degrees, and the second gap may be greater than the first gap to provide a predetermined impedance. A coaxial transmission line may form a feed inset into the loop conductor. The loop antenna may be planar and have a reduced size for ease of manufacture and use, and it may provide an isotropic radiating pattern at a predetermined operating frequency, which may avoid the need for antenna aiming.Type: GrantFiled: October 20, 2008Date of Patent: April 24, 2012Assignee: Harris CorporationInventors: Francis Eugene Parsche, Dennis Lee Tebbe

Patent number: 7808441Abstract: The antenna includes an electrically conductive antenna body having a polyhedral shape with opposing first and second ends and a medial portion therebetween. The medial portion of the electrically conductive antenna body is wider than the opposing first and second ends thereof, and the electrically conductive antenna body has a slot therein extending from at least adjacent the first end to at least adjacent the second end. The polyhedral antenna has an omnidirectional pattern, is horizontally polarized and broad in bandwidth above a lower cutoff frequency.Type: GrantFiled: August 30, 2007Date of Patent: October 5, 2010Assignee: Harris CorporationInventors: Francis Eugene Parsche, Dennis Lee Tebbe

Patent number: 7505009Abstract: The polarization-diverse antenna array includes three orthogonal loop antennas having a common center, e.g. together defining a sphere. Each loop antenna includes a loop electrical conductor. Two signal feedpoints are along the loop electrical conductor and separated by a fraction of a length of the loop electrical conductor. Each of the signal feedpoints includes a series signal feedpoint so that a polarization diversity controller coupled thereto may selectively provide vertical, horizontal, lefthand circular and righthand circular polarization for a single loop electrical conductor, including simultaneous (dual) polarizations. These signal feedpoints may supply signals with vertical, horizontal, lefthand circular and righthand circular polarization from each of the three orthogonal look-angles provided by the three loop electrical conductors.Type: GrantFiled: December 11, 2006Date of Patent: March 17, 2009Assignee: Harris CorporationInventors: Francis Eugene Parsche, Dennis Lee Tebbe
