Review on the planar endfire circularly polarized antennas
In this article,we comprehensively review the history and milestones of the endfire circularly polarized antennas.Based upon the operation principles of orthogonally combined magnetic dipoles and planar complementary dipoles,we are able to insightfully analyze the general design approaches to the planar endfire circularly polarized antennas(PECPAs)and to clearly illustrate their configuration evolution.Furthermore,we introduce the broadband,beamwidth broadening,and high gain techniques to PECPAs,respectively.Finally,we prospect possible developing trends of future PECPAs.This survey is expected to provide beneficial design guidelines to the scientific researches,as well as the engineering developments of PECPAs.
