Based on 2D meander line methods, 3 times 3 times 3 point, symmetrical, 3D dipole antennas structure was investigated exhaustively to identify those configurations with the highest efficiency and lowest resonant frequency for a fixed length. Maximum efficiency and input impedance occurs when adjacent high current segments in the antenna are oppositely directed. The optimal antenna structure was compressed and the effect of a nearby conducting plane was investigated. The meander line structure greatly improves antenna performance with a resonant frequency of 498 MHz and an efficiency of 62% when located on a conducting ground plane.Based on 2D meander line methods, 3 times 3 times 3 point, symmetrical, 3D dipole antennas structure was investigated exhaustively to identify those configurations with the highest efficiency and lowest resonant frequency for a fixed length.
