Patent number: 6806841Abstract: A three element antenna utilizes a truncated parabolic reflector dish of diameter “d” and focal point “f” and a director plate for receiving and transmitting high frequency signals in conjunction with a substantially horizontal conducting ground plane. The antenna is mounted to a planar transverse end wall, defining the lower truncated end of the parabolic surface, and the antenna elements are proximate to the focal point “f” of the paraboloid that defines the dish. The director plate is positioned at the opening (defining the diameter “d”), is distal to the focal point and the antenna elements, and positions an array of director rods about the antenna elements to focus signals relative to the parabolic surface. The ratio of (f/d) is about 0.01 to about 0.625, and preferably about 0.210.Type: GrantFiled: November 14, 2002Date of Patent: October 19, 2004Inventors: Jack Nilsson, H. Gregory Badger

Patent number: 6496152Abstract: A dual polarization antenna for receiving and transmitting high frequency signals in conjunction with a substantially horizontal conducting vehicle panel defining a ground plane comprises three electrically conductive radiative elements, each radiative element being generally linear and extending between a proximal end and a distal end, and an electrically conducting mount (insulated from the vehicle panel) for securing the proximal ends together at a common point and in electrical circuit relation with one another for connection to a transceiver in the vehicle. The radiative elements extend vertically upwardly and outwardly from the common point whereby to form an imaginary cone with the proximal ends forming the apex of the cone. The radiative elements are of different lengths and disposed at an angle relative to the ground plane to provide horizontal and vertical polarization in a first, second and third frequency band.Type: GrantFiled: March 9, 2001Date of Patent: December 17, 2002Inventor: Jack Nilsson
