5808585 Method of configuring multiple-arm antenna element in a radome  
A radome (310) made of a cylindrical tube sealed on a first end and open on a second end houses a multiple-arm antenna element (405). The radome is formed with at least two grooves (340, 350) on an...
5677699 Helical microstrip antenna with impedance taper  
A helical antenna comprised of a helical conductor having one end adapted to be connected to a feedline, a conductive surface contained within but spaced from the helical conductor, the distance of...
5479182 Short conical antenna  
An antenna suitable for mounting upon vehicles, vessels or aircraft for communication via satellites comprises a conductive ground plane and a radiator element in the form of a conductor helically...
4031539 Broadband turnstile antenna  
A truncated conical member of conductive material is mounted forward of a pair of crossed dipoles, the legs of which are inclined toward a reflector. The pair of dipoles cross orthogonal to each...
3945016 Wide-band spiral antenna  
The invention relates to wide-band, plane, spiral antennas. A conductive arm is arranged spirally in a plane close to a reflector. A resonator member positioned at the centre and in front of the...
3932876 Short end-fire circularly polarized antenna  
A circularly polarized antenna having an end fed short length helical conductor within a conductive funnel-shaped reflector is described. A broad beam width and a relatively low axial ratio is...
3795005 BROAD BAND SPIRAL ANTENNA  
Antenna elements for substantially circularly-polarized electromagnetic energy are shown. The disclosed elements, formed on a tapered form having an elliptical cross section, are particularly well...
