i) i need to use power divider to connect to array antenna.
how can i make each antenna radiate different phase (or was it pointing angle? maybe i wrong in term) if its come from one input feed. thank you
i hope, it can be realizeable without phase shifter, but if its really need the phase shifter to produce diferent phase, then at which part should i put it? is it between power divider and antenna?
thanx
ii)
i simulate my antenna and it gives negative gain, and radiation eff. of -6dB
i know the result is wrong, can anyone suggest, what can i do so that my antenna really can gives positive gain, thanx again
i and ii using microstrip technology , and CST software
