Problems solved by technology

[0005] However, as shown in FIG. 3, when the LCD display panel 32 of a PDA device 30 is 2.8 inches, 2.4 inches or smaller, the required width of the PDA device 30 is also reduced.
However, when the WLAN antenna 34 and the GPS antenna 36 need to be arranged on the top of the same side of the ground plane to obtain the best signal reception, the total length of the two antennas will exceed the width of the substrate required by the small-sized LCD display panel. Also resulting, such as the configuration of the substrate space and the saving of materials, the consideration of receiving signals, and the convenience of use

Embodiment Construction

[0038] The invention discloses an antenna configuration of a handheld communication device (such as a PDA device). In order to make the description of the present invention more detailed and complete, reference may be made to the following description together with FIG. 4 to FIG. 5 .

[0039] Referring to FIG. 4, which is an embodiment of the present invention, a schematic configuration of a PDA device is illustrated. A PDA device 40 includes a ground plane 42 , a first inverted-F antenna 44 , a second inverted-F antenna 46 , and an LCD display panel 48 . Wherein, the first inverted-F antenna 44 and the second inverted-F antenna 46 are respectively located on two sides of the ground plane 42 . The first inverted-F antenna 44 can receive signals within a first bandwidth, which includes a bandwidth for receiving GPS signals from the Global Positioning System; on the other hand, the second inverted-F antenna 46 can receive a Signals within a second bandwidth, the second bandwid...

Abstract

The invention provides a pocket communication device which includes an inverse F-shaped antenna capable of receiving and transmitting a signal in a first frequency width; a second inverse F-shaped antenna capable of receiving and transmitting a signal in a second frequency width; and a grounding plane which is connected to the first inverse F-shaped antenna through a first short circuit assembly, and is connected to the second inverse F-shaped antenna through a second short circuit assembly; wherein, the first inverse F-shaped antenna and the second inverse F-shaped antenna are respectively located at the both-side of the grounding plane.

Description

technical field [0001] The invention relates to a handheld communication device and an antenna module included therein. Background technique [0002] Hand-held communication devices with global positioning system (GPS) design are becoming more and more popular. Therefore, how to effectively arrange the GPS antenna in the hand-held communication device has become a major issue. However, in order to meet the needs of users and visual aesthetics, the importance of the appearance design of handheld communication devices such as mobile phones and personal digital assistants (PDAs) cannot be ignored, and the configuration of the antenna is a major factor affecting the appearance of handheld communication devices. one of the factors. [0003] The Inverted F Antenna (Planar Inverted F Antenna, PIFA) is widely used in handheld communication devices due to its relatively suitable shape and size. 1 is a configuration diagram of a conventional inverted-F antenna. An inverted-F antenna...
