Research On Load Compact Broadband Antenna

In this paper,a lumped loading compact broadband common-caliber planer antenna and a distributed loading travel wave linear antenna are designed and simulated.Some knowledge of compact and broadband about antenna is expounded,and the transforming relation between the linear antenna and the planer printed antenna is given.The loading antenna's theory is introduced and three integral equations used for analyzing the loading antenna are given in this paper.Because of distributed loading is hard to come ture in project ,a nearly distributed loading travel wave linear antenna is designed and simulated based on distributed loading theory.This antenna has good broadband character.Finally,a lumped loading compact broadband common-caliber antenna is designed and simulated,and the antenna has been made in fact.The electric character between the antenna model and the antenna practicality is similar.This antenna's specialty includes compact,broadband,low section and according with air dynamics.It can be used as airborne antenna.
