Vertically Polorized Omni Slot Antenna
wrote in message oups.com... So I guess the annular slot is the complement to a halo? Since I think of a halo as a loop in a plane parallel to the ground, it is difficult for me to make a comparison of it to a monopole antenna pattern. My suggestion would be for you to re-define your needs. There are some really good antenna designers contributing to this group. |

Vertically Polorized Omni Slot Antenna
I'm not the one designing the antenna. I'd build a collinear. I'm
just interested in the properties of the annular slot. What I mean by "I guess the annular slot is the complement to a halo?" is this: A halo as I know it is a half wave or so loop broken opposite the feedpoint and in a plane parallel to the ground. It has an omnidirectional azimuth pattern but radiates horizontally polarized radiation. It seems that the annular slot is a slot in a plane parallel to the ground, with an omnidirectional azimuth pattern, and vertically polarized radiation. So, is an annular slot antenna a halo cut out of a sheet? 73, Dan N3OX |
