The present disclosure refers to an antenna system vehicles, preferably for Vehicle-to-Everything (V2X) communications, comprising a planar reflector and a radiating element placed over the reflector, wherein the radiating element comprises segments, preferably straight segments, arranged to configure two connected quadrilateral frame antenna elements. Each quadrilateral frame antenna element having an inner pair of segments and an outer pair of segments, wherein the segments of the inner pairs are substantially parallel to the reflector, and the segments of the outer pairs are inclined with respect to the segments of the inner pairs. The segments of the outer pairs have one end connected with the reflector.

A cone-based multi-layer wide band antenna is provided, including a cone-based member having a multi-layer structure. The multi-layer structure includes a first layer conical structure, and the first layer conical structure has a height and a base radius configured to provide a desired impedance of the antenna.

Systems and methods improve tracking performance of an ultra-wideband (UWB) tracking tag positioned on a player on a sporting field. A UWB antenna is formed with power radiated disproportionately in forward and backward directions as compared to sideways. The UWB tracking tag is aligned with the UWB antenna when positioned on the player such that less power is absorbed by the player than radiated away from the player. The UWB antenna is monopole and may be folded from a single metal sheet forming: a flat top; a first side folded at an acute angle from one edge of the top; a second side folded at an acute angle from another edge of the top; a first solder tab folded at an obtuse angle from the first side; and a second solder tab folded at an obtuse angle from the second side, to join in parallel with the first solder tab.

An antenna system comprises a transmission member and an antenna at a distal end of the transmission member. The antenna includes a first conductive arm, an insulator extending around the first conductive arm, and a second conductive arm wound around at least a first portion of the insulator to form a second conductive arm coil. A property of the insulator varies along an insulator longitudinal axis of the insulator.
