A concept of frequency-reconfigurable circularly polarized (CP) antenna with
omnidirectional radiation characteristics is introduced. The antenna is based on a center-fed …

This paper presents a wideband reconfigurable circularly polarized (CP) antenna with
omnidirectional radiation pattern. The antenna is based on a shorted monopolar patch …

This communication introduces a polarization reconfigurable wideband circularly polarized
(CP) antenna, which consists of four radiating arms connected to a reconfigurable feeding …

This letter proposes the development of a polarization-reconfigurable omnidirectional
antenna combining a dipole and a loop radiators. The omnidirectional circular polarization …

A circularly polarized (CP) crossed-dipole antenna with switchable rotating sense is
presented. The proposed design has two main attractive features. First, a wide overlapped …

A simple compact circularly polarized (CP) cross slot antenna with a wide frequency tuning
range has been presented in this letter. Four identical varactors are loaded at the ends of the …

A novel polarization reconfigurable circularly polarized (CP) antenna is proposed in this
paper. The antenna is composed of a pair of rectangular loops and two parasitic rectangular …

A compact-size low-profile wideband circularly polarized (CP) omnidirectional antenna with
reconfigurable polarizations is presented in this communication. This design is based on a …

A pattern-reconfigurable slot-augmented patch antenna is reported that radiates circularly
polarized (CP) fields and is switchable between a broadside and a conical radiating mode …

A low profile circularly polarized (CP) antenna with reconfigurable polarization is designed
and presented, which can radiate omnidirectional patterns that can be switched between left …
