    Hello, everyone. How can man change the Gain pattern in Fernfield? for example, PIFA Antenna has often gain pattern upward to sky, I want to change the most Gain pattern to the elevation grad 90°, That means, polarisation from horizontal to vertical, how can man change the PIFA's polarisation? Have you any ideas?:starstruck:

    or another Questions: how assess the Performance from the stations antenna? we want to have a ominidirection antenna (vertical polarisation), but sometimes we can only develop not 100% vertical polarisiert antenna. then how can we know if it good Performance has?
