Abstract
In this paper, A novel spatial power combiner with wideband printed dipole antennas and balanced amplifier is proposed. The wideband spatial power combiner is proposed to improve power capability and bandwidth by using balanced amplifier and wideband printed dipole antenna, respectively, The proposed 4${\times}$1 spatial power combiner with those components has the characteristics that the 3-dB bandwidth is 1.02 GHz (17 ％), and the effective isotropic power gain (EIPG) is 24.04 dB at 6 GHz. Also, power combining efficiency is 68.69％.
