Abstract
An alternative configuration for an infinite coaxially endβfed waveguide phasedβarray antenna is explored. In the proposed configuration, the integration of the endβfed launcher and the output waveguide, rather than the waveguide in itself, acts as a basic radiator. This allows the design of more compact antenna elements. In order to analyze and optimize the structure, an accurate fullβwave simulation tool based on the multimode admittance matrix representation is developed. Results are validated against stateβofβtheβart commercial CAD software. Numerical simulations involving singly and doubly tuned configurations are presented and discussed to illustrate the potential convenience of the proposed configuration and of the CAD tool developed.
