✦ Synopsis

This paper describes a compact, self-complementary square-spiral antenna on a GaAs substrate with a broadside high-directivity (ϳ29 dB) frequency-independent pattern when coupled through a silicon hyperhemisphere. The driving-point resistance undulates between ϳ100 and 300⍀ from 200 GHz to 1 THz-much higher than the 72⍀ value from Booker's modified formula, but quite beneficial for coupling to high-impedance broadband devices.

## Abstract A compact antenna gain measurement system suitable for wireless devices is presented. The method needs the antenna under test, a planar electric conductor, and a vector analyzer. It is possible to obtain the total gain by a reflection measurement. Several simulations show a guideline to
