Combined Bowtie-Peano Antennas for Wideband Performance

The concept of the folded bowtie wideband antennas is introduced in this paper. To this aim, the design procedure employs a Peano space-filling curve approach which leads to an entire family of combined bowtie-Peano antennas (BPA). The new structures efficiently blend the broadband performance of bowtie antennas with the compactness of Peano forms. In this context, two alternative devices are proposed and thoroughly investigated. Numerical results derived by means of a finite-difference time-domain (FDTD) technique clearly reveal the behavior and the merits of the novel radiators, signifying, also, the feasibility of bandwidth enhancement at specific resonances.
