Novel broadband omnidirectional antennas

2012 Asia Pacific Microwave Conference Proceedings, 2012
Three types of novel broadband omnidirectional antennas are developed, including a circularly polarized antenna, a horizontally polarized antenna and a 45° linearly polarized antenna. All of these antennas have a bandwidth of about 30% with good omnidirectional radiation patterns.
