Tuneable antenna arrangement
The present invention relates to a tuneable antenna arrangement (101) comprising a tuneable microstrip patch antenna means comprising conducting patch means, a dielectric substrate and a ground plane. It comprises a self -oscillating mixer arrangement (61) which is electro-magnetically integrated with or in the tuneable antenna means (11,21). The self -oscillating mixer arrangement (61) is tuneable and comprises a number of, one or more, tuneable oscillators, and the tuning means are adapted to tune both the tuneable antenna means and the self -oscillating mixer arrangement (61). The tuneable antenna arrangement comprising an input terminal and/or an output terminal for input/output of low frequency intermediate and/or baseband signals.
