Since the position of the partner station 13 is not recognized by the own station 12,
The power supply phase of the antenna 6a is controlled by the phase shift unit 10 to
Type (two types in Embodiment 1. Three types in Embodiment 2.)
Class) to form an antenna composite coverage
Was. ), The communication information 3a having the same content is repeatedly transmitted to the transmission unit 4.
Output to a plurality of modulated wave signals based on these communication information.
Without transmitting the signal continuously,
To transmit the communication information 3a of the station to the partner station as a radio signal.
Communication efficiency as well as communication quality.
Mobile communication device can be obtained. In addition, transmission capacity
Large transmission capacity, if it is possible to allow
The transmission system is composed of multiple modulated wave signals from its own station.
Communication quality by having the other station transmit
Of course, it is also possible to improve. Embodiment. 5 Next, according to another embodiment of the present invention.
This will be described with reference to FIG. Books according to the above embodiments
In the mobile communication device according to the present invention, the antenna unit
Although it was composed of two antennas, the present invention
Antennas are limited to two antennas
It is not a thing. FIG. 9 shows a mobile communication device according to the present embodiment.
FIG. 4 is an explanatory view schematically showing the arrangement. In FIG. 9, 17
a to 17d are the antenna coverage areas as shown in FIG.
A mobile body on which the mobile communication device is mounted so as to have a shape.
According to the present embodiment provided at predetermined positions of
This is the antenna of the moving body communication device. In addition, according to this embodiment
In a mobile communication device, the antenna unit is connected from four antennas.
The antenna section is configured by more antennas
May be configured. According to the mobile communication device according to the present embodiment,
If the mobile communication device according to each of the above embodiments is
Because of the large number of antennas in the
The range in which the contact portion occurs can be made smaller. Ma
In the case of the mobile communication device according to the present embodiment, the phase shift unit 1
0 is a pair of antennas arranged opposite to each other,
Connected to one of the antennas. For example, in FIG.
Is the antenna 17a and the antenna 17b or the antenna 17c and
Connected to antenna 17d. And connected like this
The phase shift unit 10 is connected to the mobile communication device according to the above embodiment.
Similarly, the output status of the communication information 3a output from the continuous sending unit 9
Antenna connected based on, for example, the antenna 17a or
By switching the power supply phase of 17c, this embodiment
As described in the above embodiments,
Compensating for interferences in the radiation characteristics to achieve the same effect
Can be. [0044] According to the present invention,Multiple identical received
The communication information transmitted from the partner station is compared by comparing the communication information of the contents.
Information,Reliability of communication quality between mobiles
Can be greatly improved. [0045] [0046]
