Miniaturization of log-periodic dipole array antenna using triangular meander structure

This paper has been designed the miniaturized LPDA antenna applying the triangular meander structure. To reduce the basic LPDA antenna, four dipole elements for low frequency band of the basic LPDA antenna were changed into triangular meander structure except for the other elements to keep the performance of high frequency band. The proposed antenna was miniaturized up to 60 % compared with the basic LPDA antenna. The average gain was measured as 6.69 dBi.
