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.

Broadband antenna quality control

Upravlenie kachestvom (Quality management), 2023
This article discusses the main issues of quality control of broadband antennas. An algorithm for determining the gain, the importance of using the Helmholtz equation for determining the parameters of the electromagnetic field in the near zone of the antenna complex is considered.

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.

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.
