Redundancy Elimination of the Classic Log-Periodic Dipole Array Antenna by Resonance Point Optimization for a Miniaturized Structure

To axially miniaturize the microstrip log-periodic dipole array (LPDA) antenna, a new design method is proposed. The proposed method redistributes the LPDA’s resonance points, meanwhile reducing the number of dipoles required for a designated bandwidth. The length of each dipole is adjusted according to the proposed design formula to redistribute the resonance points while keeping the bandwidth un...
