Title: Microstrip patch antenna
Inventor: YUGAWA HIDENORI
IPC: H01Q13/08
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized microstrip patch antenna of low loss. SOLUTION: A transmission system circuit of an antenna system consists of only a power distributor 12, transmission high frequency amplifiers 13a, 13b, isolators 14a, 14b and a patch antenna element 15. Since a signal with large power amplified by the two transmission high frequency amplifiers 13a, 13b is fed to the patch antenna element 15 not via a power combiner, the antenna system has a low loss. Furthermore, since the power distributor 12, the transmission high frequency amplifiers 13a, 13b, the isolators 14a, 14b and the patch antenna element 15 are integrated on a dielectric board 10, the antenna system can be miniaturized.

Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To conduct an incoming call notice depending on a state of existence of a slave set by storing in advance a master set number and call reception non-ringer information to the main device, sending this information to the master set and driving a vibrator when the slave set received reception data. SOLUTION: A number of a master set 4 and a call reception non-ringer information are stored in advance in a RAM 16 of the main device 1 and a CPU 14 sends the information to the master set 4 when the system is started. Otherwise, instead, a pushbutton telephone set 3 sends information to the main device 1 and also to the master set 4. Furthermore, when the master set 4 conducts position registration of the slave set 5, the master set 4 sends the call reception non-ringer information from the main device 1 to the slave set 5 together with position registration data.  Upon the receipt of the cell reception non-ringer information, the slave set 5 sets the information to a built-in memory and when the slave set 5 receives call reception data from the master set 4, the slave set drives a vibrator motor call reception device section without a call reception ringer by a buzzer for call reception indication. Thus, the call reception notice is made depending on a state of the slave set.
