In such situations, the waveguide power divider network is a suitable building block for this antenna array [20], and this literature uses the four-port equivalent magic tee waveguide as the splitter, but we employ the there-port H-T waveguide as the splitter, and magic tee acts as a directional coupler and a phase shifter formed compact topological structure to design the power divider network.
The magic tee and power dividers are connected to build a compact monopulse combining network.
In summing up the advantages and disadvantages of the power splitter mentioned above, this paper proposes a new type of waveguide magic tee splitter and a compact millimeter-wave solid-state power combining scheme.
The ideal magic tee is a lossless, reciprocal four-port network and constituted of waveguide double-T and matching components.
This property of the magic tee splitter mentioned above makes achieving high isolation and ideal match much easier than a single E-T or H-T junction.
The above analysis shows that the incident energy of port 1 through the electric field coupled to the magic tee can be equivalent to capacitive coupling, while the energy of port 4 through the magnetic field coupled to the magic tee is equivalent to inductive coupling, so E-arm must be deployed by inductive components, and H-arm be deployed by capacitive elements.
The operating principle and design of compact, non-standard, reduced height waveguide planar magic tee junctions are described.
A magic tee, being the ba sic building block of a monopulse comparator, plays a very important role in making such arrays lightweight and compact.
In this article, the designs of two different types of compact planar magic tee junctions -- a planar magic tee junction (PMTJ1) using a collinear transverse waveguide slot coupler and a planar magic tee junction (PMTJ2) with a longitudinal/transverse slot coupled difference port -- have been accomplished based on MoM analysis and FEM-based CAD high frequency structure simulator software (HFSS).
A double-balanced mixer can be constructed using a balun, magic tee and diode quad.
