fig4 illustrates an integrated yagi antenna and low noise amplifier system 100 in accordance with a preferred embodiment of the present invention . the entire system 100 is preferably located on one epoxy glass fiber printed circuit board 130 . the printed circuit board 130 can be manufactured with any suitable material and is not limited to epoxy glass fiber . the system 100 consists of an f - connector 120 which attaches to the antenna transmission line of the receiver such as the radio receiver 9 . the yagi antenna system 100 is comprised of a reflector combined with a low noise amplifier ( lna ) indicated at 118 which are implemented using surface mount device technology . the reflector and lna combination 118 are in turn connected to the radiator 122 . the reflector and the lna are co - located on the same printed circuit board . this design eliminates the cables and connectors used with conventional yagi antennas which produce signal loss in front of the low noise amplifier 118 and reduce antenna sensitivity . as described below in connection with fig5 surface mount device ( smds ) are used to facilitate the connection between the symmetrical dipole feed points 112 and 114 of the radiator 122 and the lna 118 . the smds are indicated generally at 50 in fig4 . this allows for the two dipole feed points 112 and 114 to be driven approximately 180 degrees out of phase with respect to each other . as this method avoids the use of a balun cable , the complete antenna and lna system 100 of fig4 can now be implemented on one substrate 132 and can be enclosed in one housing 134 having a single mount for connection to a receiver such as the radio receivers 9 . the smds can be mounted on the printed circuit board 130 , specifically substrate 132 , of fig4 and encased using a plastic material , for example , to more easily accommodate folding of the antenna . the encasing material is not limited to plastic , but can be any material that is appropriate . such a design is more compact than a conventional yagi antenna having coaxial sheath and core connections to the respective dipole feed points 112 and 114 . the preferred embodiment of the present invention employs a folded dipole as the driven element for ease with impedance matching , but an open dipole design could be used as well . further , the type of driven element is not limited to an open or folded dipole design , and any appropriate design can be employed . fig5 illustrates the smds 50 which are preferably two capacitors 52 and 54 and an inductor 56 . the capacitors 52 and 54 each have one terminal connected to opposite terminals of the inductor 56 and the other terminal connected to ground 62 ( e . g ., the backplane of the substrate 132 ). the feed line 60 , which is preferably implemented using micro - strip technology on the substrate 132 , is connected to the feed point 114 . the smds 50 allow for the signal on the feed line 60 directly connected to one of the dipole feed points 114 to be approximately 180 degrees out of phase with respect to the signal on the opposite feed point 112 of the folded dipole . the smds 50 are useful for antennas in a satellite broadcast system 100 , since such systems preferably use a limited bandwidth of about 1432 - 1512 mhz or in the s - band range of 2630 - 2655 mhz . the same design can be utilized in applications with higher or lower bandwidths , but the number of smds is adjusted to correlate to the bandwidth . to further reduce the cost of the antenna and lna system 100 , antenna operation is preferably linear , as opposed to circular , polarization . fig3 shows the circular polarization technique . as mentioned above , circular polarization employs costly and duplicate components to process the left - hand and right - hand polarized signals . in order to meet the need for a low cost receiver , many components are eliminated or at a minimum reduced in number in the present system 100 by employing a linear reception mode for the circularly polarized signals . benefits of a linear technique are the need for only one low noise amplifier input stage , and the elimination of the polarization switch and control logic to switch between the right - hand and left - hand polarized signal channels . in addition , one linear antenna can feed multiple receivers . the preferred embodiment of the present invention is able to employ this linear signal processing mode for left - hand and right - hand circularly polarized signals because the satellite broadcast system 100 does not require cross - polar separation . in addition to the difference in the polarization mode , the individual signals are displaced in frequency , thereby permitting the receiver tuning and selectivity to opt for either the right - hand or left - hand signal . since only one component of the circular radiation field is used , there is a signal loss of 3 db . this loss is compensated for by increasing the gain of the antenna by adding parasitic elements , thus enlarging the size of the antenna this is less expensive than using , alternatively , the configuration of fig3 . addition of these parasitic elements or directors is easily accommodated by the foldable design . the metallic axis within the fold of the antenna can be used as one of the magnetically coupled directors . this design allows for more room on the substrate 32 for placement of additional directors if needed . as an additional benefit , this higher directivity offers better protection against interference , especially in the case of a linear interfering signal where the antenna can be decoupled by orienting it accordingly . furthermore , users generally do not experience difficulties with antenna pointing , as the antenna lobe is still rather wide as shown in fig6 . the 3 db gain reduces the lobe width typically to 70 %. fig6 shows the polar rotational diagram of a beam pattern for the antenna and lna system 100 . the beam pattern demonstrates the ability of the antenna to deliver quality signals despite sub - optimum orientation by the user and further how much gain the antenna delivers if the antenna is turned slightly . for example , at optimum pointing , or 0 degrees , the antenna achieves a 9 db gain this does not drop off to 8 db until approximately 15 degrees away from optimum pointing . furthermore , the antenna gain reaches 0 db at approximately 40 degrees . this figure shows the antennas tolerant gain despite the users error during antenna orientation . the antenna system described herein offers many advantages since all of the components of the antenna and lna system 100 can be placed on one printed circuit board . there is no need for bulky cables or connectors or for impedance matching . this allows for a simple design that facilitates portability of the radio receiver . since the antenna can be placed on one printed circuit board , the present invention realizes reduced cost , and reduced likelihood for manufacturing tolerances and faults , allowing for the capability of excellent mass production . the preferred embodiment of the present invention employs linear signal processing as opposed to circular polarization processing to further reduce cost due to a reduction in the number of components in the system . although the present invention has been described with reference to a preferred embodiment thereof , it will be understood that the invention is not limited to the details thereof . various modifications and substitutions will occur to those of ordinary skill in the art . all such substitutions are intended to be embraced within the scope of the invention as defined in the appended claims .
