Yep, that was the Art of Star Trek - the antenna was unopened and the backstory was:
John Eaves had to draw new comm(badges) for STVII, and since TOS, he hadn't seen the badges and the further development. So he drew some concepts including this, went to Herman Zimmerman (with other people in the room), presented these and... Herman was shaking his head, while other were laughing, and Herman asked him: "What is THIS?." "These are the comms concept you requested," answered John, a little bit taken aback, and others were going hysterical. "John, things had changed since you saw TOS..." said Herman and gave him a couple of tapes, where he could see, how a combadge looked like. He slunked back to his drawing board and made several concepts, which included the VOY combagde we saw on TV.
