Various applications require an antenna to provide coverage in the azimuthal plane while still retaining a\nlow profile. Transformation Optics method can be used to provide novel solutions to fulfill this objective. In this paper,\nthe design of dielectric superstrate inspired from Transformation Optics has been reported which completely reorients\nthe electromagnetic waves emanating from a directive antenna in the azimuthal plane. The physical space is modeled\nusing a virtual space composed of two opposed quarter circles. It is shown analytically that a dielectric-only solution\ncan be obtained from the transformation relations. Use of shift and compression factors has been applied to the\nmaterial parameter profile to achieve the reorientation. A full wave solution has been presented which reorients\nthe radiation pattern of a classical patch antenna in the azimuthal plane. The solution can be fabricated from isotropic\ndielectric materials.
