发明名称 PORTABLE RADIO COMMUNICATION EQUIPMENT
摘要 PURPOSE:To obtain an antenna diversity branch with a small correlation characteristic by providing an antenna to both of two cases turnable at one connection part. CONSTITUTION:Antennas 121, 122 are provided to both of two cases 102, 103 freely-rotatable at one connection part and an antenna is selected based on the reception quality. That is, the 1st antenna 121 and the 2nd antenna 122 are connected to separate printed circuit boards 110, 111 and the printed circuit boards 110, 111 are covered by different chassis 102, 103. Thus, the distribution of a high frequency current flowing to the printed circuit boards 110, 111 or the chassises 102, 103 is different specially when the antennas 121, 122 are energized to acquire a different radiation characteristic. Thus, the portable radio communication equipment provided with plural antenna diversity branches and excellent correlation characteristic is realized.
