Description
Technical field
The utility model relates to a kind of tunable antenna and assembles the portable terminal of this tunable antenna.
Background technology
Mobile terminal antenna develops towards miniaturization, thereby causes the bandwidth wretched insufficiency of antenna.For solving this technical barrier, wherein a kind of technology is the tuned antenna technology, like " tunable antenna of wireless communication terminal " (number of patent application CN03802748.8), " tunable antenna layout " (number of patent application CN200880129992.0); " tunable antenna assembly " (number of patent application N02829928.0), " reconfigurable mobile phone built-in antenna and its implementation " (number of patent application CN200910215550.4).
Above-mentioned technical disadvantages:
The technology that the foregoing invention patent adopts all has some shortcomings, as resonance frequency changes easily when switching different coupling, but the impedance of antenna can not keep optimum, and just standing-wave ratio can shoal.This can cause antenna when some resonance condition, and it is optimum that coupling can not reach.Fig. 3 a adopts the standing wave pattern of this tuned antenna technology at different matching status, can see, resonance point resonance is when low more, and standing-wave ratio is high more.
The utility model content
For guarantee be tuned to all keep good coupling, the utility model that a kind of tunable antenna is provided during each state and assemble the portable terminal of this tunable antenna.
A kind of tunable antenna that the utility model provides comprises radiating principal, coupling feed element and switch switching device; Said radiating principal and said coupling feed element adopt slot coupling, and said switch switching device switches pin through switch and is carried on the said radiating principal.
This tunable antenna can also comprise the ground connection parasitic patch, and said radiating principal, said coupling feed element and said ground connection parasitic patch adopt slot coupling.
Preferably, said coupling feed element is provided with the antenna feed pin, and said radiating principal is provided with the radiating principal grounding leg.
Said switch switching device can be PIN diode, switch chip or other switching device.
The portable terminal that the utility model provides is equipped with the described tunable antenna of the next item up.
The mainboard of said portable terminal can be used as the ground plane of said tunable antenna.
Matching element can be inductance, electric capacity, microstrip line etc.
The radiating principal of ground connection is drawn near grounding leg when switching pin, switches the sensitiveness to frequency tuning with the far and near coupling that determined of the distance of grounding leg.
The grounding leg of radiating principal can omit, and this moment, the resonance frequency of radiating principal was determined by the coupling that switching device joins.When connecing perceptual device, resonance frequency reduces, and when connecing capacitive device, resonance frequency increases.
The utility model has been realized the tunable of antenna resonance; Guarantee that each tuning state can both reach Optimum Matching; Through frequency tuning and impedance matching, the utilized bandwidth of extended antenna; For being suitable for the antenna technology of ultra-thin all-metal portable terminal.
Further, the utility model adopts slot coupling mode feed, and current path changes for a short time on the coupling unit, and high frequency performance changes little.The antenna efficiency of slot coupling feeding classification is than higher.Tuning control manner is next tuning for only on the ground connection radiating principal, loading different couplings, and the ordinary load mode can be communicated with on the feed path, perhaps on parasitic patch, loads.The impedance phase complementation of the tuning and slot coupling unit of radiating principal is repaid, and still keeps best coupling when causing tuning big frequency deviation.In conjunction with the high parasitic technology, further reduce switch and switch the influence that high frequency is brought.
The tunable antenna of the utility model switches different coupling expansion low-frequency bandwidth through control, and is realizing five above frequently bandwidth coverings limited environment under, assurance simultaneously be tuned to all keep good coupling during each state.The tunable antenna of the utility model can be widely used in ultra-thin multifrequency portable terminal.
