Computation of radiation patterns of rhombic antennas with log periodic dipole array termination

In this letter, the effect of terminating resistance loss in the case of rhombic antennas has been studied. Generalized analysis has also been made to compute the radiation pattern of rhombic antennas with the log periodic dipole array termination. Theoretical radiation patterns are plotted and it is observed that this new method improves the directivity and lowers the sidelobe level.
