Abstract

In un'antenna per dispositivi rice-trasmittenti o simili, allo scopo di eliminare la presenza di modulatatori e demodulatori separati e gli annessi circuiti l'invenzione prevede di associare un diodo rivelatore/miscelatore (6) alla struttura radiante (1) d'antenna, in modo tale da costituire un unico dispositivo che è alternativamente atto a ricevere un'onda portante modulata e a demodulare dalla stessa i segnali di modulazione in ricezione nonchè a modulare, con dei segnali di modulazione locali, un'onda portante, riflettendola ad esempio indietro verso la sorgente emittente. I segnali di modulazione in ricezione ed i segnali locali di modulazione in trasmissione, vengono rispettivamente prelevati ed alimentati alla struttura radiante (1) in un punto (P) della stessa, in cui il campo elettrico dell'onda portante è pari a zero. Il punto d'inserzione (I) del diodo rivelatore/miscelatore (6) nella struttura radiante (1) è determinato in modo da ottenere un ottimale adattamento tra l'impedenza della struttura radiante (1) nel punto d'inserzione (I) e del diodo rivelatore/miscelatore (6), in ricezione ed in trasmissione.
