Hello,
Can someone please check my radiation pattern for a multiband coaxial fed patch antenna and tell me if they are fine. If not, what should be the improvements?
1. Is it necessary that the radiation pattern be observed at phi=0 and phi=90 only ?
2. Is it fine to have a negative gain at phi=0 and positive at phi=90 ?
3. Is there a particular pattern to be observed ?
4. Should we check gain or directivity ?
