ABSTRACT:
There are disposed first coupling conductors, which comprise a pair of coupling branch lines1and2connected to the first antenna conductor3and extend inward from the first antenna conductor. The coupling branch lines1and2have open ends1aand2adisposed so as to be adjacent to each other and be capacitively coupled to each other. The open ends1aand2aof the coupling branch lines1and2are located at closest or substantially closest portions to each other. The second antenna conductor13includes second coupling conductors, which comprise a pair of coupling branch lines11and12connected the second antenna conductor13and extending inward from the second antenna conductor. The coupling branch lines11and12have open ends disposed so as to be adjacent to each other and be capacitively coupled to each other. The open ends of the coupling branch lines11and12are located at closest or substantially closest portions to each other.
