Abstract: A gain-optimized, compact helical antenna array comprises an array of tapered pitch angle helical antenna elements. By tapered pitch angle is meant that the pitch angle increases from the base end of the antenna element to the distal end, in a manner that optimizes the gain of each helical element relative to helix length for a given physical size of the winding. Each helical winding is coupled to a signal distribution network, through which the antenna's radiation pattern is controllably defined. The antenna elements have a spatially aperiodic distribution, that reduces grating lobes, by minimizing the number of antenna elements which share the same azimuth. A radial line orthogonal to the boresight axis will intercept a minimum number of helical antenna elements of the array. To minimize mutual coupling, the mutual spacing between any two antenna elements of the array is at least a prescribed minimum separation that is proportional to a product of the square root of the gain of the respective antenna element and the wavelength of the operating frequency of the array.

Abstract: A communication terminal including a communication unit, a longitudinal antenna enclosed in a radome, and a pivot connecting the antenna to the unit for pivoting about an axis with an RF connection to the unit. The unit is in a box-shaped enclosure having a front face with a keypad and connected to a rear face by top and bottom faces, and two side faces. One of the unit front and rear faces is non-planar from top to bottom with the spacing between the front and rear faces varying from top to bottom. The spacing between the radome front and rear faces varies to substantially match the varied spacing between the unit front and rear faces so that the radome and unit front and rear faces define a uniform profile when the radome is adjacent one unit side face. The unit top face lies on one side of a first plane and at least one unit side face lies on one side of a second plane perpendicular to the first plane. An L-shaped support secured to the unit supports a pivot shaft defining the pivot axis substantially parallel to both of the planes and spaced on the other side of both of the planes by distances allowing the antenna to pivot through a 270 degrees range. A plurality of detents are spaced about the pivot shaft, and a detent mechanism secured to the antenna engages one of the pivot shaft detents in each of a plurality of pivoted positions. The radome has two shells connected substantially along a plane, with longitudinally spaced ribs supporting the antenna in a position spaced from the shell outer walls.

Abstract: A variable helical antenna comprises coaxial conductive first and second helices extending in the same direction. The helices have first portions interleaved with each other without being in mechanical contact. A fixed protection member made in insulative material contains at least a portion of the first helix. A second member made in insulative material is screwed to the first member and contains at least a portion of the second helix. The second helix is attached to the second member. On screwing/unscrewing, the second helix is moved helically, by sliding on itself, relative to the first helix in order to tune the antenna to a required frequency indicated on a graduation on the fixed protection member.
