Advantages and Disadvantages of Log Periodic Dipole Antennas
Antennas are of different kinds and work differently according to the radiation pattern, characteristics, and frequency range. Log Periodic antenna is a type of antenna that contains multiple dipoles with various lengths and spaces. It might look like a Yagi antenna but both of them have some differences. In a log periodic antenna, the dipole elements reduce in size and have different lengths. In this blog, we will discuss the Advantages and Disadvantages of Log Periodic Dipole Antennas in detail with other things. Construction of Log periodic antenna LPDA or log periodic antenna is constructed by using the different half-wave dipole elements with increasing length. It is designed in such a way that the electrical properties will show periodic repetition with frequency logarithm. In this antenna, the different dipoles of various lengths and spacing are put together. External excitation in an LPDA is given by using the balanced transmission line. This line is exchanged betwee
