A tactical broadband omnidirectional antenna

2008 Asia-Pacific Microwave Conference, 2008
In this paper, a vertically polarized broadband antenna with an adjustable shape for specific applications in the VHF and UHF bands is proposed. This antenna is a compact monopole with a pseudo-conical shape set on a rectangular ground plane, partially made of wire netting.

A broadband microstrip antenna: SGMFP antenna

Microwave and Optical Technology Letters, 2003
AbstractA novel structure of broadband microstrip antennas, termed the SGMFP antenna, is proposed. It is consisted of a slot in the ground plane, a microstrip feedline supported on a substrate, a foam layer, and a patch. It can achieve broad bandwidth and high polarisation purity.

Broadband Antennas

2016
Apart from the sleeve monopole, this chapter discusses other broadband antennas as well, and the performance evaluation in terms of various measured and simulated parameters is also illustrated. This chapter will help antenna engineers get a better understanding of the antennas discussed and make a comparison with other broadband antennas.

Broadband semiloop antenna

Microwave and Optical Technology Letters, 2002
AbstractAn unbalanced loop antenna of simple construction is proposed for broadband linearly polarized applications. By introducing a gap in a half loop mounted vertically over a ground plane, the bandwidth of the antenna can be substantially increased relative to its classical balanced version.
