Transformation Electromagnetics Miniaturization of Sectoral and Conical Metamaterial-Enhanced Horn Antennas

Résumé

The synthesis of compact metamaterial-loaded sectoral or conical horn antennas matching the radiation properties of larger layouts is addressed. Unlike state-of-the-art strategies, the metamaterial lens that fills the miniaturized horn is designed so that the radiated field coincides with that of the reference arrangement both in amplitude and phase. To this end, the synthesis is first recast as a 3-D transformation electromagnetics (TE) problem, then mapped into an equivalent 2-D one. This latter is numerically solved by means of a recently introduced 2-D quasi-conformal TE algorithm. Selected examples from a wide numerical validation and representative comparisons with state-of-the-art methodologies are illustrated.
