A novel omnidirectional circularly polarized (CP) slot array antenna with high gain is proposed, which is based on the coaxial cylinder structure, and the orthogonal slots radiated the circular polarization wave around the cylinder. Further, the improved dual circularly polarized (CP) omnidirectional antenna based on slot array in coaxial cylinder structure is presented too, and two ports are ... High gain waveguide slot array antenna for 60 GHz point-to ... High gain waveguide slot array antenna for 60 GHz point-to-point communication FARID HADAVY Department of Signals and Systems CHALMERS UNIVERSITY OF TECHNOLOGY Abstract The 7GHz license free allocated frequency band around 60GHz is very attractive for both indoors and outdoors communication such as 4G/LTE backhaul, wireless An Omnidirectional Circularly Polarized Slot Array Antenna ... Abstract: In this letter, a novel omnidirectional circularly polarized (CP) slot array antenna with high gain is proposed. The array is based on the coaxial cylinder structure. The omnidirectional radiation is realized by four perpendicular slot pairs surrounding the axis of coaxial cylinder in the outer conductor, which can be seen as a basic omnidirectional CP element.

The Steatite family of sinuous antennas simultaneously handle signals of any two orthogonal linear polarisations and simultaneous left and right-handed circular polarisations dependent on antenna design.. This provides intercept opportunities for a wide range of arbitrarily polarised signals, from devices also giving a wide bandwidth and broad beamwidth. Split-Beam Mode Four-Arm Slot Sinuous Antenna | Request PDF Request PDF on ResearchGate | Split-Beam Mode Four-Arm Slot Sinuous Antenna | A coplanar waveguide (CPW) center-fed four-arm slot sinuous antenna is introduced in this letter. The antenna A ultra wide band sinuous antenna design with enhanced Vivaldi antennas, which cannot be easily extended to polarization-agile applications. The sinuous antenna is both radiation efficient and can be used with polarization agility in its 4 arms version without excessive complications. However, conventional two-arms sinuous antennas do present a linear polarization which oscillates in frequency. Enhanced-Gain Planar Substrate-Integrated Waveguide Cavity
