The hybrid antenna system also includes a displaceable antenna, such as a whip antenna, that is selectively extendable from and retractable with the casing. The antenna system includes a mechanism for electrically connecting the displaceable antenna to internal RF circuitry of the portable WCD when the displaceable antenna is in an extended position and for electrically isolating the displaceable antenna from the internal RF circuit when the displaceable antenna is in a retracted position within the casing.
Description
Background of invention
Invention field
The present invention relates generally to antenna, relates in particular to a kind of hybrid antenna system that is disposed in the portable radio communication device and comprises replaceable telescopic antenna and concealed antenna.
Correlation technique
In recent years, at personal radio communication equipment (WCD), also quickened the demand growth of the suitable antenna aspect that is used for WCD simultaneously as the phenomenal growth of cell phone use aspect.This arrangement of antennas is being ordered about in some important requirements, comprises that lower antenna element cost and production cost, compact size, omnirange gain and suitable frequency bandwidth, high reliability, the attractive in appearance or outward appearance of pleasing the people and comfortable ergonomics external packing.
Normally used a kind of type of antenna configuration comprises elongation pull bar or one pole/dipole antenna.In a kind of known configuration, telescopic antenna can be stretched selectively or be collapsed into honeycomb telephone shell.Even when the his or her head, stretched telescopic antenna is still advantageously kept an omnirange gain diagram relatively uniformly at user's portable cellular phone, because stretched telescopic antenna stretches out from cell phone and user's head.Therefore, telescopic antenna is fit to be operated in the relatively low received power environment, for example, and the edge in signal covering area or sub-district.On the other hand, because the elongation of antenna also can bring disadvantage, the outstanding profile of telescopic antenna elongation makes it be damaged easily, and more sensitive consumer attractive in appearance is caused clumsy sensation.
Cell phone often comprises a helical antenna that is used in combination with telescopic antenna, and is energized when telescopic antenna is stretched from honeycomb telephone shell.The radiator length of this helical antenna usually and the same length of telescopic antenna, although helical antenna is compacter than telescopic antenna, the more happy people of outward appearance and more difficult being damaged.However, helical antenna still will outwards be given prominence to from cell phone in fact and always, will cause adverse effect to cellular outward appearance like this, and make helical antenna be damaged easily.
Thereby cell phone manufacturer provides other more happy people's in appearance antenna to substitute pull bar and helical antenna, as all placing within the honeycomb telephone shell, and is subjected to the inside antenna of its protection.A kind of so built-in antenna allows the cell phone manufacturer structure slicker and more sly, outward appearance more happy the people's and aspect ergonomics more gratifying cell phone.Because inside antenna is encapsulated in cell phone inside, thereby it is adapted to operate in the higher relatively or normal environment of received signal power, but is unsuitable for being operated in the relatively low edges cover zone of received signal power.Equally, though it is more acceptant than telescopic antenna in appearance, but hold the shell of close inside antenna the user, or hand-held housing is near his or her head, therefore and when making inside antenna near head, inside antenna (and above-mentioned helical antenna) is disadvantageous antenna gain variation owing to antenna load has formed.
Therefore, in the antenna system of Wireless Telecom Equipment (WCD), need get up the feature performance benefit of telescopic antenna with outward appearance and the ergonomics advantages relevant with inside antenna, and minimizing and every kind of shortcoming that antenna type is relevant.
Summary of the invention
The invention provides a kind of hybrid antenna system that is used for portable WCD.This hybrid antenna system comprises the concealed inner shield substrate antenna of integral installation regularly in portable WCD housing.Hybrid antenna system can also comprise removable antenna, and as telescopic antenna, it can be stretched selectively or collapses among the shell.This antenna system comprises and is used for when removable antenna is in stretch position removable antenna being electrically coupled to the internal RF circuit, and a kind of mechanism that when removable antenna is in punctured position in the shell removable antenna and internal RF circuit electricity is isolated.
In first embodiment, inside antenna is all worked and is coupled to the RF circuit when removable antenna is in the stretching service position or shrinks off-position.Like this, inside antenna and removable antenna are worked abreast and are linked together when removable antenna is in stretch position, and all are connected to the RF circuit by work, but when removable antenna is in punctured position, have only inside antenna to be connected to the RF circuit.
In a second embodiment, can only there be one in removable antenna and the inside antenna to be coupled to the RF circuit sometime.Particularly, when being in the stretching service position, have only removable antenna to be coupled to the RF circuit, and when removable antenna is in inoperative punctured position in the WCD shell, have only inside antenna to be coupled to the RF circuit.Second embodiment comprises the arrangement of two kinds of duplexers.First kind of arrangement comprises a kind of mechanical switch that is used for switching between antenna, and second kind of arrangement comprises the electronic switch that is used for switching between antenna.
Electric coupling can realize with direct electrical connection, inductance or conduction coupling or other effective means.
Feature and advantage
This hybrid antenna system gets up the feature performance benefit of telescopic antenna with outward appearance and the ergonomics advantages relevant with concealed inside antenna among the portable WCD.
At WCD between the normal operating period, just cover goodish the time at signal, telescopic antenna shrinks and hides in the WCD shell, and is in non operating state.The concealed inside antenna of work provides satisfactory performance in this case.Like this, most of the time, it is slick and sly that WCD can keep, more happy people's outward appearance.Yet, covering under the relatively poor situation at signal, the user can resist relatively poor signal covering by the higher telescopic antenna of tensile property effectively, and has therefore enlarged the usable range of WCD.
This hybrid antenna system makes up and arranges in direct mode with less relatively and known assembly, to reduce manufacturing complexity, cost and the size of antenna system.
