摘要：
This paper presents a hybrid-log periodic dipole antenna (H-LPDA) which is a cost effective alternative to the regular planar-log periodic dipole antenna (PLPDA). In case of a PLPDA, required substrate dimensions increases with bandwidth as we have to accommodate dipoles of shortest dimensions to the longest. In order to make the antenna more cost effective in terms of the high frequency substrates used, a 3D structure is incorporated with the PLPDA while keeping the overall dimension as well as the performance same as the original PLPDA. In this paper, a PLPDA designed to operate over 700MHz - 4.5GHz is replaced by the proposed H-LPDA design. The design is simulated, fabricated and measured. The antenna is found to have performance similar to that of the original PLPDA antenna with good impedance matching (VSWR<2) and a stable radiation pattern with a gain of 6.5dB over the desired operating band.
