Abstract :
An approach to complex-plane field manipulation in an antenna element using amplitude-based control has been developed. Such a capability is expected to be especially useful in phased array applications. This specific example of the general approach uses a circular microstrip patch (CMSP) antenna. The theoretical basis for the approach is presented along with a summary of simulation data that validate the theory. A new accuracy analysis across angular space is presented.
