A shaped-beam antenna is proposed using bifilar helix antenna. The antenna is fed by a notched balancer. The radiation pattern and the axial ratio changing with the helix pitch distance are simulated in the paper. The measured gain and |S11| are also given. The antenna has a wide bandwidth of more than 40% with conical radiation pattern and circular polarization. It can be used in outer space communications due to its low profile and high reliability.
