This paper describes a compact, self‐complementary square‐spiral antenna on a GaAs substrate with a broadside high‐directivity (∼29 dB) frequency‐independent pattern when coupled through a silicon hyperhemisphere. The driving‐point resistance undulates between ∼100 and 300Ω from 200 GHz to 1 THz—much higher than the 72Ω value from Booker's modified formula, but quite beneficial for coupling to high‐impedance broadband devices. © 2006 Wiley Periodicals, Inc.
