Description

Palm type communication apparatus with rotable antenna

Technical field

The invention provides a kind of palm type communication apparatus, particularly a kind of palm type communication apparatus with rotable antenna.

Background technology

In recent years, with progressive, the popularity rate of palm type communication apparatus also raise successively in response to the flourish of mechanics of communication, and in present society, everyone on average has a kind of hand held communication apparatus at least.So-called palm type communication apparatus embraces a wide spectrum of ideas, for example mobile phone, personal digital assistant etc.Although these different types of palm type communication apparatus have different intrawares in response to function is different, basic outfit all comprises an antenna, be used for receiving and the transmission radio-frequency (RF) signal, and a transceiver, be used for handling this radio-frequency (RF) signal.For all communication devices on the market, good signal receiving/transmission quality is very important, and therefore, antenna is just being played the part of very important role.If the pairing direction of antenna can only receive faint radio-frequency (RF) signal, this signal just can't be given transceiver and handle, can cause whole communication apparatus to lose the most basic communication function like this, thus, function miscellaneous is of no avail even if this communication apparatus has other kind.

So that global positioning system (global position system to be provided, GPS) hand held communication apparatus is an example, belong to the high directivity antenna because be applied to the antenna of this kind communication apparatus, just the user need aim at the signal source with the normal direction of antenna place housing and just can receive satellite signals, so in order to promote the receptivity scope of antenna, prior art is to add a rotating shaft between communication device body and antenna, by this rotating shaft, the user can adjust the direction of antenna, allow its rotation in space once, the satellite-signal power that receives in order to adjustment.See also Fig. 1, Fig. 1 was for before having global positioning system (global position system, GPS) schematic diagram of the hand heldcommunication apparatus 10 of function,equipment 10 comprise first housing, 12, oneprocessors 13, be installed infirst housing 12, be used for deal with data, atransceiver 15 is installed infirst housing 12 and is coupled toprocessor 13, be used for handling radio-frequency (RF) signal, onedisplay panels 8 is installed on this first housing, is used for video data, onesecond housing 14, oneantenna 11 is installed insecond housing 14signal line 17, be coupled toantenna 11 andtransceiver 15, be used for transmitting radio-frequency (RF) signal, and a rotatingshaft 16, be connected infirst housing 12 in rotating mode, one side-line ofsecond housing 14 is fixed in the rotatingshaft 16, and thereforesecond housing 14 can rotate with respect tofirst housing 12 along with rotatingshaft 16.

Yet the antenna of previous hand held communication apparatus is because can only rotate on a two-dimensional space, so limited to its signal scope that can receive.See also Fig. 2 and Fig. 3, not have schematic diagram under the rotation situation, Fig. 3 be hand heldcommunication apparatus 10 to Fig. 2 rotates schematic diagram under 180 situations about spending at itssecond housing 14 at itssecond housing 14 for hand held communication apparatus 10.Label 18,22 onantenna 11 is the normal ofantenna 11, promptly is perpendicular to the direction of paper.As position such as Fig. 2, shown in Figure 3 ofsecond housing 14, and the direction that transmits of satellite signals is during withlabel 18 parallel (promptly perpendicular to paper), but thenantenna 11 receives the effect of signals with optimization.Yet, when satellite signals are to be transmitted toward the below by the top of paper, indicate asarrow 20, or be to transmit toward left by the right-hand of paper, when indicating asarrow 21, becauselabel 18,22 presents orthogonality relation witharrow 20 andarrow 21 respectively, so antenna can't receive the satellite signals that transmitted byarrow 20 andarrow 21 directions.See also Fig. 4, Fig. 4 is the schematic diagram of hand heldcommunication apparatus 10 under the situations of its second housing, 14 rotations, 90degree.Arrow 24 is the normal ofantenna 11, promptly be towards left and right directions, in this case, becausearrow 24 is parallel witharrow 21, butantenna 11 receives the effect of signal with optimization, yet becausearrow 24 andarrow 20 present orthogonality relation,antenna 11 will still can't receive the satellite signals thatarrow 20 is transmitted.

Comprehensive above observation, can learn that prior art is in the 10 added rotatingshafts 16 of hand held communication apparatus, owing to can only allowantenna 11 do the rotation of a two-dimensional directional, so satellite signals that transmitted for some direction (asarrow 20 directions), what can't receive arrives, unless the user changes the direction of ornaments hand held communication apparatus 10.But the user is for fear of spatial limitation sometimes, and can't change the direction of ornaments hand heldcommunication apparatus 10, therefore makes that the effect ofantenna 11 received RF signals can't optimization.

Summary of the invention

The present invention discloses a kind of palm type communication apparatus with rotable antenna, it comprises one first housing, and a rotating shaft is being coupled to this first housing with respect to the mode that this first housing rotates, one second housing, being coupled to this rotating shaft with respect to the mode that this rotating shaft is rotated, an antenna is installed in this second housing, be used for receiving and dispatching radio-frequency (RF) signal, and a signal line, be coupled to this antenna, be used for transmitting radio-frequency (RF) signal.
