Abstract

A class of volume-optimized pyramidal log-periodic antennas (PLPAs) with an adjustable ultra wideband performance is introduced in this paper. To this aim, a parametric analysis is initially conducted to decrease the total size of the prototype Euclidean-toothed PLPA. The new structures are based on the concept of meander curves, which leads to efficient substitutes of the conventional device with drastically reduced dimensions, but equivalent behavior. For the design procedure, the radiation features of all antennas are accurately evaluated via a 3-D finite-difference time-domain (FDTD) algorithm. Extensive investigation reveals that the prior volume-confinement method and the proposed radiators can provide very compact setups for a variety of modern communication systems.
