The diplexer connects the transmit (Tx) and the receive (Rx) frontend with an antenna element. It is comprised of a bifurcation and two second order bandpass filters with low insertion loss. The Rx-filter has additionally two transmission zeros in the Tx-band. The structure is implemented in multilayer printed circuit board (PCB) technology. This yields a compact design which can be integrated in an array with half-wave element spacing. The simulated diplexer performance is validated by measurements. The insertion loss in the Rx-band remains below 0.7 dB, while the Tx-/Rx-isolation exceeds 40 dB in a 1.2 GHz band at Tx.||URI:||http://hdl.handle.net/11420/2722||ISBN:||978-398203970-1||Institute:||Hochfrequenztechnik E-3||Type:||InProceedings (Aufsatz / Paper einer Konferenz etc.)||Funded by:||German Aerospace Center (DLR) on behalf of the German Federal Ministry of Economics and Technology (BMWi) under research contract 50 YB 1707.||Project:||Elektronisch schwenkbare Planarantenne für mobile Satelittenkommunikation im Flugzeug - SANTANA-Aero|
