This excellent answer to First Ham Radio contact from space; what frequency, what kind of antenna, and how did they route the coax out the window? in Space Exploration SE contains the block-quoted material below.
Question: What might a "split-ring on a printed-circuit board" antenna for 144 MHz transmitting through a downward-looking Space Shuttle window look like? How big would it be?
This happened on the first Spacelab flight, STS-9.
The antenna (split-ring on a printed-circuit board) will be placed in the upper crew compartment window on the aft flight deck.
