Abstract

In this paper, low noise amplifier(LNA), aperture coupled patch antenna and $4{\times}4$ array antenna are designed in the frequency range from 11.7㎓ to 12㎓. Array antennas with and without LNA at the antenna element are fabricated and the performances are measured including noise figure(NF). The noise figure calculation for overall system was conducted and compared with the measured data to verify our measurement method. The measured overall noise figure of the array antenna with LNA at the antenna element is lower than that of array without LNA as expected.
