ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a notebook and, more specifically, to a notebook with a retractable antenna installed in a housing.
2. Description of the Prior Art
Notebooks are now commonly used for personal computing. Because they are small and light, notebooks are suitable to be taken out of the home or office for document processing. Because wireless transmission techniques are maturing, hard-wire connection with electric network lines is no longer needed to transmit electrical signals, and signals may be received or transmitted from anywhere in a wireless manner.
As wireless transmission techniques develop, antenna
112
design becomes important. Please refer to FIG.
1
and FIG.
2
.
FIG. 1
is a schematic diagram of a notebook
100
according to the prior art.
FIG. 2
is a function block diagram of the notebook
100
in FIG.
1
. The notebook
100
comprises a housing
102
, a memory
104
installed in the housing
102
for storing programs
105
and data
106
, a processor
108
electrically connected with the memory
104
for processing programs
105
and data
106
, a display panel
110
installed in the housing
102
for displaying picture images, and an antenna
112
. The antenna
112
is set on a motherboard inside the housing
102
of the notebook
100
. Therefore, the antenna
112
often does not receive signals properly, due to a limited bandwidth.
SUMMARY OF THE INVENTION
It is therefore a primary objective of the present invention to provide a notebook with a retractable antenna, installed in the housing, that has a higher bandwidth.
It is another objective of the present invention to provide a notebook of which the status of the antenna can be known.
According to the claimed invention, a notebook comprises a housing, a memory installed in the housing for storing programs and data, a processor electrically connected to the memory for processing programs and data, a display panel installed in the housing for displaying picture images, a retractable antenna installed in the housing and an LED for signaling on and off of the antenna.
It is an advantage of the present invention that the antenna protrudes from the housing, when in use, so as to achieve higher bandwidths.
It is another advantage of the present invention that the LED can signal on and off of the antenna so that a user can know the status of the antenna.
These and other objectives and advantages of the present invention will no doubt become obvious to those of ordinary skill in the art after having read the detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
