dear all,
can any one help me to measure the radiation pattern of a horizontal polarized omnidirectional antenna. i have the radiation pattern test set up with me... i have some doubts..
1. A vertical polarized monopole antenna is mounted on a ground plane and connected vertically (azimuth plane / perpendicular to the ground) and the same is exited with a simple
log periodic antenna (as per fig 1).
Result: the pattern is omni-directional
2. The same antenna is mounted horizontally ( elevation plane / parallel to the ground) and the same is exited with a simple log periodic antenna (as per fig 2).
Result: the pattern is similar to "figure of 8"
3. Now i want to measure the azimuth radiation pattern of a horizontal polarized omni directional antenna. pls suggest me in azimuth plane & in elevation plane how to
fix the antenna? in which plane we will get omni patten? pls suggest which figure is azimuth? Pls seeFigure3 & 4
thanks for your time in advance
