In this paper, a new form of endfore, traveling wave antenna, is described in the form of a triangular line with a corner reflector. It consists of a conductor folded into elements each of which is an equilateral triangular loop with the length of the side larger than one half wave length. The radiation patterns are measured at X-band. The endfire radiation exists over a bandwidth of approximately 21 per cent with a sidelobe level better than 20 db for 3-loops. The half power beamwidth ranges approximately from 5°.1 to 7°.5 for 5-loops.
