LANFRANCO HERRERA, Pablo; CEPERO LLAUGER, Karen; MEDIAVILLA SANCHEZ, Ángel  y  MARANTE RIZO, Francisco. DESIGN OF A TM01 COMPACT MODE COUPLER FOR TRAKING MONO-PULSE SYSTEMS. EAC [online]. 2014, vol.35, n.2, pp. 1-10. ISSN 1815-5928.

A mono-pulse tracking mode coupler design for satellite communications and radio astronomy is presented. The device utilizes two parallel slots for sensing TM01 higher order mode which made the system more compact along with a very small size. The mode sensors are joined by an H plane T junction. A prototype was fabricated and tested for the Ku-band (12,3-13,8 GHz) for validate the theoretical results. The return loss obtained on the tracking port are better than -22dB. The return loss corresponding to the main signal are better than -25dB through the frequency band of work. These tracking systems utilize circular polarized signals.

Palabras clave : mode coupler; higher order mode; circular polarization; compact system; mono-pulse tracking system.
