Abstract
A low-noise active receiving antenna based on a printed dipole and a Si-SiGe HBT in the 5.8 GHz band is presented. A power gain of 8.3 dB compared to the respective passive antenna and a noise figure of 1.4 dB at center frequency were achieved. To improve the antenna gain, two of these components were combined with a small array with reduced beamwidth and comparable noise figure
