This paper proposes a planar Log-Periodic Dipole Array(LPDA) antenna with light-weight supporting structure for installing on an aircraft. The proposed antenna is designed by applying a planar skeleton supporting structure that has light-weight for an aircraft and is capable of withstanding structural vibration. The material of the planar skeleton supporting structure is a Polyether ether ketone(Peek) which has excellent characteristics on strength and temperature. The proposed antenna is fabricated by attaching the radiating elements of the LPDA on both sides of the supporting structure. The changed input impedance due to the dielectric material of the supporting structure was compensated for by controlling the distance and length of several radiating elements. The 10-㏈ return loss bandwidths of the designed planar LPDA antenna with light-weight supporting structure are obtained as 0.4～3.1 ㎓(7.3:1) in the simulation and 0.41～3.5 ㎓(8.2:1) in the measurement. The average gains in 0.5～3 ㎓ band are 6.77 ㏈i in the simulation and 6.55 ㏈i in the measurement. Therefore, we confirm that the designed antenna is appropriate to be installed on an aircraft due to its light-weight structure and wideband directional radiation characteristics.
