  Abstract

In this paper, a compact log periodic dipole array (LPDA) antenna operating from 1 to 6 ㎓ is studied. Inverted-L shaped dipole elements are used to miniaturize the lateral size of an LPDA antenna and the spacing factor is also decreased to reduce the total length of the LPDA antenna. As the top-loading length of the inverted-L shaped dipole elements is increased, the width of the LPDA antenna is decreased but the bandwidth and the gain of the antenna are decreased. The fabricated compact LPDA antenna is printed on FR4 substrate with a dielectric constant of 4.4 and a thickness of 1.6 ㎜, and its size is reduced to 32% in width and 49% in length compared to a standard LPDA antenna.
