Abstract
The authors describe a 1 lambda slot antenna with a layered structure loaded with two 1-port reactive FET components electromagnetically. By changing bias voltages, the reactance of the FETs varies and the length of the slot is tuned electronically. The resonant points of S/sub 11/ measurements were shifted over a range of 1 GHz around 10 GHz. The antenna patterns are essentially unchanged in spite of this electronic tuning.Keywords
