Abstract

An optimized design of Microstrip Log Periodic Dipole Array (MLPDA) antenna with non-cross feed structure is reported in this paper. Particle Swarm Optimization (PSO) is utilized to reduce the size and enhance the bandwidth of proposed antenna. Proposed design employs an improved feed structure of non-cross feed array antenna to avoid complexity of conventional feeding with long coaxial line and creating Co Planar Waveguide (CPW) feed. A simple FR-4 substrate with thickness of 1 mm is utilized for simulation using CST. A fitness function based on S₁₁ parameter is used to achieve the optimization goal. A prototype of proposed PSO optimized antenna is developed to validate the simulation results. The proposed antenna offers higher bandwidth and significantly smaller size than cross feed LPDA antennas, with less complexity and low cost through parameter optimization, while maintaining the log periodic nature and gain.
