  • Helical antenna
    Patent number: 7038636
    Abstract: 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.

  • RF microwave bellows tuning post
    Patent number: 5986526
    Abstract: An adjustable RF microwave tuning post for use in an RF cavity is disclosed. It is comprised of a flexible integrally-formed hollow tuning post disposed in the RF cavity. A drive shaft extending internally of the tuning post is provided to vary the dimensions of the tuning post. The drive shaft is connected to the tuning post at the top end thereof and connected at the other end of the drive shaft to an adjusting nut. The tuning post is made flexible by the use of bellows, which in a preferred embodiment of the invention is located along the side walls thereof.
