Phase shifter is a key component of electric tilt antenna. The loss and matching characteristics of a common phase shifter are analyzed in detail, thus the possible resonance loss and mismatch are pointed out. In addition, the measures which should be avoided and taken are put forward for designing this kind of phase shifter.
