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. Amazon.com: High Gain Free To Air TV Antenna - Portable ... Note: I just verified that the August DTA240 High Gain Digital TV Aerial may be a very good option to consider. This antenna has a gain of 3.0 which means it will make the signal three times stronger than the DTA180. For a few dollars more this may be an excellent option in areas where stations may be further away or more difficult to receive. Spiral antenna - Wikipedia In microwave systems, a spiral antenna is a type of RF antenna. It is shaped as a two-arm spiral ... Array of spiral antennas can be used to increase the gain. ...

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
