摘要： Example apparatuses and methods relating to antennas are provided. An example apparatus in the form of an antenna assembly includes a first conductor structurally formed into a plurality of first conductor structural waves and a second conductor structurally formed into a plurality of second conductor structural waves. The first conductor and second conductor may be helically wound to form a bifilar helix structure having a proximal end and a distal end. The first conductor and the second conductor may be operatively coupled at the proximal end of the bifilar helix structure to form a signal feed point, and the first conductor and the second conductor are operatively coupled at the distal end of the bifilar helix structure to form a load point.

摘要： A helical antenna has a helix supported by a helix support. The helix support includes at least one piece of flexible sheet having its two surfaces covered with a layer antistatic material. The flexible sheet is curlable into a revolution surface configuration to form a revolution surface-shaped support section for at least partially supporting a portion of the helix component there around. A grounding mechanism electrically grounds the external sheet surface to the helix and the two sheet surfaces to one another when in the revolution surface configuration while a locking mechanism locks the flexible sheet in the revolution surface configuration. The combination of the helix and the flexible support renders the antenna structurally relatively rigid in all directions.
