Broadband Circularly Polarized Antenna With Non-Planar Reflector
IEEE Access, 2020 In this article, a compact broadband circularly polarized (CP) antenna with non-planar reflector is presented. In this antenna, two fan-shaped cross-dipoles as the primary radiator and a stepped ground as a reflector are proposed to generate a broadband ...

Broadband Multilayered Array Antenna with EBG Reflector
International Journal of Antennas and Propagation, 2013 Most broadband microstrip antennae are implemented in the form of slot structure or laminate structure. The impedance bandwidth is broadened, but meanwhile, the sidelobe of the directivity pattern and backlobe level are enlarged. A broadband stacked slot

On the Design of Conical Antennas for Broadband Impedance Matching Performance
International Journal of Antennas and Propagation, 2017 In the scope of broadband radiators, the biconical antenna, or its monopole conical counterpart, is long known to be a proper choice. One common form of such radiator, the spherically capped conical antenna (SCCA), has closed-form solution to its input ...

A broadband horizontally polarised omnidirectional antenna with stable radiation patterns
The Journal of Engineering, 2019 A broadband horizontally polarised omnidirectional antenna (HPOA) with stable radiation patterns is proposed. The antenna is composed of two orthogonal broadband HPOA units fed by a wideband power divider.

Electronics Letters, 2006 A new class of reconfigurable antenna based on monopole structures containing liquid dielectrics is presented. It was determined that the operating principle of this class of antenna is essentially that of a dielectric resonator, where salt (in solution) modifies the dielectric properties. The resonator column height determined the operating frequency,
