Abstract
A compact and broadband Log-periodic dipole array antenna with curved bow-Tie elements is proposed to achieve endfire radiation. Curved bow-Tie elements are used for broadband frequency response and to decrease the size of the antenna in lateral direction. To reduce the size of the antenna along the boom length, the two end elements are made flat at one side and curved on the other side. The proposed antenna has a compact size (0.36λL × 0.1λL) and it provides 42.1% bandwidth for VSWR < 2, peak gain of 4.3 dBi and a better figure of merit.
