Substrate influence on flat folded dipole bandwidth
Abstract
The theoretical influence of a dielectric constant on the bandwidth of a flat folded dipole is discussed. The dipole offers a large bandwidth, and performs best when a low dielectric substrate is used and when it acts at both third and fourth resonances. The dipole is compared with a rectangular patch of approximately equal metallic radiating area, substrate thickness, and resonant frequency. The results indicate that the dipole can be easily matched with the classical characteristic resistance of a shielded stripline. The theory and experiments are found to be in good agreement.
