Design of Miniaturized Logarithmic-Periodic Antenna

Abstract

This paper presents a design of logarithmic-periodic antenna for frequency band 500 MHz to 4000 MHz. In order to decrease antenna dimensions, the longest radiation elements are bent. The antenna in the whole frequency band has a voltage standing wave ratio lower than 2 and achieves a gain exceeding 8 dBi, while its width was reduced by 7.89 %.
