Estimating the term…
An antenna array system which comprises at least one balanced antenna having an electric neutral point and two output end terminals positioned closely to each other, at least one unbalanced antenna having one end thereof dc-coupled with the electric neutral point of the balance antenna and the other end thereof positioned closely to the end terminals of the balanced antenna, first means for picking up a first frequency wave signal such as FM wave signal from the balanced antenna, and second means for picking up a second frequency wave signal such as an AM wave signal from the unbalanced antenna.
An antenna array system comprising at least one loop antenna having an electric neutral point and two output terminals positioned closely to each other, at least one rod antenna having one end terminal thereof electrically coupled with the electric neutral point of said loop antenna and the other end thereof positioned closely to the end terminals of said loop antenna, first means connected to the output end terminals of said loop antenna, for picking up a first frequency wave signal caught by said loop antenna, and second means connected to the other end of said rod antenna, for picking up a second frequency wave signal caught by said rod antenna and being different in frequency from said first frequency wave signal, said first means including balanced variable reactance circuit connected to the output terminals of said loop antenna and having a reactance variable with a first control dc voltage;
