Fig. 1, Fig. 3 and Fig. 4 show the exemplary reflector 108 that can use together with antenna module 100.As shown in Figure 3, reflector 108 comprises the surface 160 of general planar or plane.Reflector 108 also comprises relative to surface 160 outward extending baffle plates, antelabium or sidewall portion 164.Reflector 108 generally can be used for roughly towards gradual change type loop antenna element 104 reflection electromagnetic wave.

As for size and its spacing to antenna element of reflector, inventor notices following situation.The size of reflector and have strong impact to performance to the spacing of antenna element.Antenna element is placed to from reflector very close to antenna will be made to have good gain, but but have narrower impedance bandwidth and poor VSWR (voltage standing wave ratio).Although size reduces, such design is unsuitable for the broadband application expected.If antenna element is placed to from reflector too away from, then gain declines due to unsuitable phasing.If suitably select the size of antenna element and ratio, the size of reflector, baffle dimensions and the spacing between antenna element and reflector, then can produce a kind of like this structure of the best, namely, it makes full use of and is coupled with the near region of reflector element less in electric, thus produce the impedance bandwidth increased, alleviate phase place simultaneously and compensate for effect.Final effect is in impedance bandwidth, directivity or forms exemplary balance between gain, emission effciency and physical size.

In execution mode shown in this, reflector 108 is roughly has the square of four perimeter sides wall portion 164.Alternate embodiments can comprise the reflector with different structures (such as, difformity, size, less sidewall portion etc.).Sidewall even can be made to be inverted, to make the opposite side of its directional antenna element.The effect of sidewall is to increase a little effective electric size of reflector and improves impedance bandwidth.

In size, the reflector 108 of an illustrative embodiments has long and the wide general square shape surface 160 being about 228 millimeters.Continue this example, reflector 108 height that also can have relative to surperficial 160 is all about the perimeter sides wall portion 164 of 25.4 millimeters.The size (the same with all sizes illustrated by this paper) that this paragraph provides is only used to the object illustrated and the example provided, thus any antenna element disclosed herein such as can be configured with different sizes according to specific purposes and/or by the signal being received by antenna module or send.Such as, another execution mode can comprise the reflector 108 with the baffle plate, antelabium or the perimeter sides wall portion 164 that are highly about 10 millimeters.Another execution mode can have baffle plate, antelabium towards the rightabout reflector 108 of antenna element.In such execution mode, also can be unlimited box increases by a top, and this top can be used as the radome of receiver card or other electronic components.

With further reference to Fig. 3, otch, opening or recess 168 can be set in the perimeter sides wall portion 164 of reflector so that the installation of reflector 108 in housing 116 and/or the attachment of housing extremity piece 120.In an illustrative embodiments, reflector 108 can be positioned in housing 116 (Fig. 1) slidably.The fastener hole 172 of housing extremity piece 120 can be aimed at the opening 168 of reflector, thus securing member can be inserted through the opening 168,172 of aligning.Alternate embodiments can have the reflector not having above-mentioned opening, otch or recess.

Fig. 1, Fig. 3 and Fig. 4 show the exemplary Ba Lun 112 that can use together with antenna module 100, and this Ba Lun is used for changing balanced circuit into non-equilibrium circuit.In the illustrated embodiment, antenna module 100 comprises the printed circuit board (PCB) with Ba Lun 112.The PCB with Ba Lun 112 is connected to gradual change type loop antenna element 104 (Fig. 3) by securing member and fastener hole 132 and 136.Alternate embodiments can comprise for Ba Lun 112 being connected to the different device of gradual change type loop antenna element and/or the dissimilar transformer except printed circuit board (PCB) Ba Lun 112.

As shown in Figure 1, housing 116 comprises extremity piece 120 and middle part 180.In this special example, extremity piece 120 is detachably connected to middle part 180 by machanical fastener, fastener hole 172,174 and thread socket 176.Alternate embodiments can comprise have be integrally formed, the housing of fixing extremity piece.Other execution modes can comprise the housing with one or more dismountable extremity piece, and the middle part of these extremity pieces and housing is clasped, frictional fit or interference engagement, and does not need machanical fastener.

As shown in Figure 2, housing 116 roughly takes the shape of the letter U, and it has the isolated upstanding portion or component 184 that are connected by approximate horizontal component or part 186.In the present embodiment, these components 184,186 cooperatively define the roughly U-shaped profile of housing 116.

Housing 116 can be formed by various material.In some embodiments, housing 116 is formed by plastics.Be used as at antenna module in those execution modes of exterior aerial, housing can be formed by if weatherizing material (such as, the material etc. of waterproof and/or UV resistant).In addition, housing 116 (or bottom it) also can by the material of relatively high coefficient of friction being provided to be formed for the bottom surface of housing 116.Correspondingly, this contributes to again preventing antenna module 100 from sliding relative to the surface end face of TV as shown in figure 11 (such as, etc.) for supporting this assembly 100.

In some embodiments, described antenna module also can comprise built-in or be positioned at the digital tuner/transducer (ATSC receiver) of housing.In these illustrative embodiments, the digital signal that digital tuner/transducer can be used for antenna module receives is converted to analog signal.In an illustrative examples, the reflector with baffle plate and the lid be inverted can be used as the radome of ATSC receiver.Shielding box reduces the transmitting acted on tuner circuit or the effect receiving interference.Be placed on by tuner in this cover and saved space and eliminated the possibility that (or reduce) antenna element be coupled with tuner, their coupling script is by the impedance bandwidth of antenna and directivity generation adverse influence.

In various embodiments, antenna module 100 is tuned to (being optimised in some embodiments) receive frequency range about the signal of 470 megahertzes to HDTV (High-Definition Television) (HDTV) correlated frequency of about 690 megahertzes.In such execution mode, in narrower scope, this antenna module 100 tuning receives these HDTV signals and makes antenna element 104 can be less, but can also play function fully.By each physical size that this is less, the overall dimension of antenna module 100 can be reduced, thus reduce taking up room of antenna module 100, such as at indoor use antenna module 100 and when antenna module 100 is placed on (such as Figure 11 etc.) on TV, this point is favourable.

Now the object just to illustrating is provided the exemplary operating parameters of antenna module 100.These running parameters can be changed for other execution mode, such as, according to specific purposes and the signal that will be received by antenna module.

In some embodiments, antenna module 100 can be configured with running parameter substantially as shown in figure 12, and this Figure 12 shows the gain/directivity of the computer simulation of the illustrative embodiments of the antenna module 100 for the non-equilibrium coaxial feeder with 75 ohm and S11 to the relation of frequency (in units of megahertz).In other embodiments, the balance double lead of 300 ohm can be adopted.

Figure 12 roughly shows that antenna module 100 has the gain curve of the relatively flat in about 470Mhz to about 698Mhz.In addition, Figure 12 also shows, antenna module 100 has the maximum gain (decibels for isotropic gain) of about 8dBi and the output of about 75 ohmages.

In addition, Figure 12 also shows S11 in the frequency band of about 470MHz to about 698MHz lower than-6dB.Value lower than the S11 of this value ensure that antenna carries out good coupling and works under greater efficiency.

In addition, antenna module also can be configured to a certain extent without the need to pointing to target.In such illustrative embodiments, antenna module need not again point to target when each change television channel or redirect.
