Ka-Band Coplanar Magic-T Based on Gap Waveguide Technology

A coplanar Magic-T is proposed based on a combination of ridge and E -plane groove gap waveguides for Ka -band applications. All four ports of the proposed Magic-T are coplanar. The impedance bandwidth of the proposed Magic-T is about 43% covering the whole Ka -band from 26 to 40 GHz. The Magic-T i...

Zusammenfassung:	A coplanar Magic-T is proposed based on a combination of ridge and E -plane groove gap waveguides for Ka -band applications. All four ports of the proposed Magic-T are coplanar. The impedance bandwidth of the proposed Magic-T is about 43% covering the whole Ka -band from 26 to 40 GHz. The Magic-T isolation is better than 40 dB in the whole bandwidth while its insertion loss is about 0.25 dB.
