The present invention relates to an antenna and an antenna module for receiving a satellite signal or a gap filler signal on the ground, and more specifically, a GPS (Global Position System), a Digital Multimedia Broadcasting (DMB), and a Digital Audio Broadcasting (DAB). The present invention relates to a non-square patch antenna of a ceramic dielectric block for receiving satellite signals or gap filler signals, and an integrated antenna module including the same.

In recent years, the use of wireless communication is rapidly increasing, and in order to meet the popularization of wireless communication devices, a slim antenna that can be mounted inside a transceiver according to the trend of focusing on design and cost reduction and mass production while maintaining the performance of the antenna Demand is rising.

In general, a microstrip patch antenna is used in a vehicle receiver for using mobile multimedia information, a broadcasting service, or a current location and an electronic map service. The reason is that in order to minimize the influence of the ionosphere interference and the multipath signal (noise) reflected from the ground, the satellite transmits a right hand circular polarization and receives the GPS satellite signal. Circular polarization antenna is used because patch antenna is cheap and good reception rate among various kinds of circular polarization antenna. The patch antenna is a kind of antenna that is light in weight and has a flat structure that takes up little space but can have the largest gain and directivity in a given space. It is used as a communication relay antenna of various mobile communication devices and portable devices. .

1 is an exploded view showing the structure of a patch antenna according to the prior art as the top and bottom surfaces.

As shown in FIG. 1, the square patch antenna of a conventional feeding pin type includes an antenna module 12 and a printed circuit board (PCB) 14 separated therefrom. The antenna module 12 is coated with a conductive material on both end surfaces of the dielectric block 11, the feeding pin 13 is located on the top surface. In addition, one or more low noise amplifiers (LNAs) 15 are formed on the PCB 14, and the PCB 14 is attached to the bottom surface of the antenna module 12. The conductive surface of the top surface is coated with a conductive material in the same ratio of width and length to implement circular polarization characteristics. In addition, the feeding pin 13 is electrically connected to the conductive surface of the upper surface and penetrates the dielectric block, but is formed to be electrically separated from the ground surface made of the conductive material of the lower surface.

However, the problem of the patch antenna used in the conventional navigation and the like is that a ground plane, for example, basically a flat conductive surface is required, and the ground plane of the PCB must be secured to the sky in order to facilitate reception of satellite signals. . In addition, the size of the smallest patch antenna currently used is 18 × 18mm, it is difficult to mount in the user equipment due to the limitation of the width of the receiver and the antenna height problem. Thus, as can be seen in Figure 2 showing a navigation with a square patch antenna as described above, the antenna mechanism 18, which can be unfolded and folded from the body, is located behind the top of the navigation 17, and within Since there is no choice but to configure the patch antenna to be positioned, there is a problem that the antenna mechanism protrudes laterally as much as the width of the antenna when used.

In recent years, as the trend toward slimmer and smaller portable devices has been combined with the functions of products, for example, a car navigation company needs to develop a navigation device that can be mounted on a vehicle and is portable with a built-in battery. However, as described above, the conventional patch antenna does not become slim and increases the size of navigation and the like, and even when mounted in a vehicle using a small patch antenna of 13 × 13 mm or less, the antenna characteristics are not good, so it is received in a shaded area. There is also a problem of this instability.

Meanwhile, according to the miniaturization trend, there have been attempts to use a smaller patch antenna or a linear polarization antenna of 13 × 13 mm or less, but the smaller the antenna, the lower the performance and reception sensitivity of the antenna, for example, a signal of -130 dbm is used. In the case of existing GPS engines, signal processing is not possible. Therefore, in the current market, there is a demand for the development of an antenna or an antenna module that can be built to satisfy the miniaturization and portability while maintaining or exceeding a conventional antenna.

The present invention has been made to solve the structural problems and design problems of the receiver, such as navigation according to the use of the conventional square patch antenna described above, the patch is located on the non-square dielectric ceramic dielectric block and the non-square dielectric block By adjusting the conduction pattern of the antenna, the circular polarization characteristics are obtained by extending the conductive pattern on the top surface of the non-square patch antenna of the ceramic dielectric block having the circular polarization characteristic or the improved linear polarization characteristic, and the side of the non-square ceramic dielectric block. To provide a non-square patch antenna of a ceramic dielectric block having a linear polarization characteristic or a linear polarization characteristic, and to implement a conductive pattern formed with one or more grooves in the upper end of the dielectric block to mount a patch antenna having circular polarization characteristics inside the user equipment Facilitating It is an object to provide a body antenna module.

In addition, by implementing the integrated antenna module to attach the patch antenna and the low noise amplifier to a single PCB, and the integrated antenna module to attach the patch antenna and the GPS engine module to a single PCB, the reception performance of the antenna is as good as the conventional antenna The object of the present invention is to develop an antenna or an antenna module that can be maintained or more and can be built to satisfy miniaturization and portability.

Non-square patch antenna according to the present invention for achieving the above object, the antenna for receiving a satellite signal or a gap filler signal of the ground, comprising: a ceramic dielectric block formed in a non-square having a horizontal and vertical ratio; And a conductive pattern applied to the upper end of the ceramic dielectric block, and the circular polarization characteristic or the linear polarization characteristic is adjusted by adjusting the size of the conductive pattern.

Here, the dielectric constant of the ceramic dielectric block is preferably implemented with a dielectric constant of 3 or more.

An antenna module according to the present invention for achieving the above object, the non-square microstrip patch antenna for receiving a satellite signal or a ground gap filler signal; At least one low noise amplifier amplifying a signal received by the micro strip patch antenna to a signal level that can be processed by an engine; A printed circuit board to which the micro strip patch antenna and the low noise amplifier are attached; And a transmission line for transmitting the signal amplified by the low noise amplifier to the engine.

Hereinafter, a non-square patch antenna and an integrated antenna module according to the present invention will be described in detail with reference to the accompanying drawings.

3 to 5 illustrate embodiments of a non-square patch antenna of a ceramic dielectric block having a linear polarization characteristic according to the present invention, and FIG. 3 is a cross-sectional view of the non-square patch antenna of the ceramic dielectric block according to the present invention. The top surface, the side cross section, and the bottom surface of 1 Example are respectively shown.

As shown, the patch antenna according to the first embodiment of the present invention is a feeding pin type patch antenna, which is composed of a ceramic dielectric block 21 and a conductive pattern 22. Here, the ceramic dielectric block (hereinafter also referred to as 'dielectric block') 21 is formed in a non-square, the conductive pattern 22 is applied to the upper end of the dielectric block 21 when implementing a linear polarization characteristic. In this case, the ratio of the width and length of the conductive pattern 22 is less than 13mm in width, the length of the patch antenna to be mounted in the interior of the user equipment such as navigation, the vertical shape is 18 ~ 35mm or more than 35mm square shape If the set width space is allowed, such as 7-inch navigation, it is preferable to implement the antenna characteristics by increasing the width (shortening) of the ceramic dielectric block to 13-18mm.

When the circular polarization characteristic is implemented, the conductive pattern 22 applies the conductive pattern to the circular polarization characteristic regardless of the shape of the dielectric block 21 at the upper end of the dielectric block 21, and generally implements the circular polarization characteristic. Unlike a conductive pattern that implements linear linear polarization, the conductive pattern length in the long axis direction of the dielectric block 21 tends to be shorter than the conductive pattern length in the short direction of the dielectric block 21.

In addition, in order to implement a conductive pattern having a λ / 2 electrical length corresponding to a GPS frequency on the top surface of the dielectric block 21 within the size of the dielectric block 21, a powder having a dielectric constant appropriate for the dielectric block size is first selected. shall.

The feeding pin 23 is electrically connected to the conductive surface of the upper end in the conductive surface 22 of the upper end of the patch antenna, and penetrates through the dielectric block 21 and electrically to the conductive surface 24 of the lower end. It is formed to be separated.

Figure 4 is a view showing the top, side and bottom surfaces of a second embodiment of a non-square patch antenna of a ceramic dielectric block according to the present invention.

As shown, the patch antenna according to the second embodiment of the present invention is a surface mount technology (SMT) type antenna, and the front surface of the top surface of the dielectric block 31 of the patch antenna. Although the drawing 32 is electrically insulated from the ground surface of the bottom surface, the inside of the hole 34 is filled with silver (Ag) differently from the manner in which the feeding pin 23 of the first embodiment protrudes from the bottom of the dielectric block. As a result, the input / output terminal 33 and the conductive surface 32 of the upper end of the dielectric block are electrically connected to each other and penetrate through the dielectric block 31 and open to the ground surface 35 made of a conductive material at the lower end thereof. The shape of the dielectric block 31 and the conductive pattern 32 at the upper end is the same as that of FIG. 3.

5 is a view showing third embodiments of a non-square patch antenna of a ceramic dielectric block according to the present invention.

As shown, the patch antenna according to the third embodiment of the present invention is another patch antenna of the SMT type, wherein the conductive surface 42 of the upper surface of the dielectric block 41 is made of a ground material (conductive material of the lower surface). 43 and a conductive input / output terminal 44 electrically separated from the ground conductive surface 43 at the lower end thereof, and a conductive pattern 45 formed on one side thereof to match the input / output terminal. Is made by applying SMT. Also in this case, the shape of the dielectric block 41 and the conductive pattern 42 of the upper end is the same as described above.

The patch antenna may implement various types of patch antennas using various materials. However, the patch antenna according to the present invention uses a ceramic dielectric having a high dielectric constant of 3 to 60, thereby improving performance (gain x bandwidth and volume). However, since it can be small and have a low profile, it contributes to the miniaturization of a communication device and has an advantage of being built-in so that there is little risk of damage to external impact on the device. In addition, the ceramic antenna according to the present invention can exhibit a sufficient performance in the frequency range of several hundred MHz to several GHz used by most systems, such as wireless communication or mobile phones, the use area will be broadened in the future.

The square patch antenna according to the prior art has a narrower beam width of the antenna because the same width and length are reduced when the navigation width is narrow, and only a small frequency satellite signal is received. There was a problem. On the other hand, if the non-square patch antenna according to the present invention is designed to have the characteristics of circular polarization, the short axis direction has the same level of gain as the existing patch antenna, but the antenna gain and satellite reception rate are improved compared to the existing square antenna in the long axis direction. Therefore, despite the small size, it is possible not only to receive a wide range of satellite signals but also to compensate for the reception performance by using a GPS engine such as SIRstar 3 with improved signal processing characteristics.

The non-square patch antenna of the ceramic dielectric block according to the present invention has a circular polarization characteristic by forming a conductive pattern on the side of the dielectric block and the ceramic block having a different width and length, or the characteristics of the linear polarization according to the size adjustment of the conductive pattern. The non-square patch antenna of the ceramic dielectric block to be improved is also a miniaturized antenna than the conventional square patch antenna, can be mounted inside the user equipment and has an effect of improving the reception performance.

6 is a view showing a fourth embodiment of a non-square patch antenna of a ceramic dielectric block according to the present invention.

The patch antenna according to the present invention implements a conductive pattern 78 having a groove formed by removing one or more conductive patterns on both sides of the shorter side of the dielectric block 76 having different ratios of width and length, and feeding pins. 77 is located in the conductive surface 78 of the upper end of the patch antenna, and electrically connected to the conductive surface of the upper end of the patch antenna, penetrating the upper and lower surfaces of the dielectric block 76, and the ground conducting surface 79 of the lower end. ) Is electrically isolated. The patch antenna has two antenna characteristics of a linearly polarized wave type, each of which is separated by high frequency and low frequency at 13 mm on one side. As the grooves are added while removing the shorter side of the conductive pattern, the width of the conductive pattern narrows to less than 13 mm, shifting the characteristics of other linearly polarized antennas in the 1.8 Ghz band to approximate another low frequency linearly polarized characteristic. As a result, each linearly polarized antenna characteristic has a circular polarization characteristic with a frequency, magnitude, and phase angle of 90 degrees. Particularly, in the case of circular polarization characteristics, the polarization can be miniaturized while maintaining the reception characteristics of the conventional patch antenna, and polarization is realized by implementing a conductive pattern on a long-shaft dielectric ceramic block having a high quality (Q * f: Qulality characteristic of a material) characteristic. In addition to taking advantage of the low loss of circular polarization, it has better characteristics against noise than a square antenna.

In addition, when the high dielectric constant of 30 or more is used as the ceramic dielectric block 76a and the short side of the non-square ceramic dielectric block 76a is sufficiently large by 12 mm or more, the conductive pattern 78a disposed on the non-square ceramic dielectric block 76a. Unlike in FIG. 6, even if the conductive pattern is not formed on the side of the ceramic dielectric block 76a (side), or there is no groove in which the conductive pattern on the short side is removed, the circular pattern may be circularly polarized by the conductive pattern 78a on the top surface. do.

The patch antenna in which the groove is formed in the conductive pattern is not limited to the above-described specific embodiment, and by applying all of the embodiments according to the present invention, circular polarization characteristics can be realized by various types of non-square patch antennas of feeding pin type or SMT type. Can be. In particular, non-square patch antennas, such as 13 × 18mm or 13 × 20mm, can realize circular polarization characteristics by extending the conductive pattern to the side of the dielectric block, but the length of one side is considerably longer like a 13 × 25mm patch antenna. In this case, it is preferable to implement circular polarization characteristics by forming a groove in the conductive pattern of the upper end while extending the conductive pattern on the side.

According to the embodiment of the patch antenna according to the width of the user equipment such as navigation, the length of the patch antenna is 13mm, since the horizontal implements a linear shape of 18 ~ 35mm or more than 35mm, it can be mounted inside the user equipment. In addition, while reducing the size of one side, it is possible to improve Q * F by using a high dielectric constant of Er 60 or less. For example, a 13 × 18 mm patch antenna can use ceramic powder with a relative dielectric constant (Er) of 45 with a Q * F of 40,000 or more, while a 13 × 20 mm patch antenna has a dielectric constant of 35,000 with a Q * F of 35,000 ( By using ceramic powder of Er) 37, the loss caused by the raw material can be reduced, the antenna gain can be improved, and the reception characteristics are better than that of the conventional square patch antenna.

Signals up to the second amplification are sent to the GPS engine via a connected cable. The low noise amplifier has a problem of narrowing bandwidth due to miniaturization according to a high dielectric constant of an antenna that can be used in the antenna module, thereby amplifying the received satellite signal to be processed by a GPS engine. There is also a method of attaching the patch antenna directly to the GPS engine, but in this case, since the satellite signal is too weak to be vulnerable to noise, the GPS may be amplified by gain of at least 24 dB through amplification and filtering by a low noise amplifier as described above. It is desirable to have a signal input to the engine.

Thus, according to the configuration in which the patch antenna 81 and the low noise amplifier 82 are attached to different surfaces of the PCB 83, the effect of noise from the low noise amplifier generated from the signal transmission process to the non-square patch antenna is minimized. It also has advantages.

According to the antenna module of this configuration, the PCB stage 84 to which the low noise amplifier 82 is attached has an advantage of free 360 ° rotation. That is, when spatial constraints and bending in the receiver are required according to the use of the coaxial cable, not only an antenna module may be implemented as shown in FIGS. 11 to 13, but the present invention is not limited thereto. It is possible.

Thus, according to the configuration in which the patch antenna 81 and the GPS engine module 91 are attached to different surfaces of the PCB 92, the effect of noise on the patch antenna in the low noise amplifier of the GPS engine module generated in the signal transmission process is affected. It also has advantages that can be minimized.

16 is a view showing a sixth embodiment of an integrated antenna module according to the present invention.

Two blocks of the PCB 93 having the non-square patch antenna 81 attached to the ceramic dielectric block according to the present embodiment and the PCB 94 having the GPS engine module 91 connected thereto are connected to each other using a coaxial cable 95. do. In this case, both PCB stages may have a rectangular shape, but the present invention is not limited thereto, and may have a constant shape. The coaxial cable may be replaced with a flexible PCB. According to the antenna module of such a configuration, the PCB stage 94 to which the GPS engine module 91 is attached has an advantage of free 360 ° rotation. That is, when spatial constraints and bending in the receiver are required according to the use of the coaxial cable, not only the antenna module may be implemented as shown in FIGS. 21 to 23, but the present invention is not limited thereto. It is possible.

In this case, the GPS engine module may be implemented as an integrated unit of a low noise amplifier and a miniaturized GPS engine, a GPS engine itself without a low noise amplifier, or a band pass filter and a GPS engine. Therefore, those skilled in the art can design the GPS engine module as needed, and in general, it is preferable to integrate a miniaturized GPS engine, a band pass filter, and a low noise amplifier of one stage.

In the above described and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims Various modifications can be made by those skilled in the art, and such changes are within the scope of the claims. For example, the amplifier is not limited to the integrated antenna module or the integrated GPS antenna engine module according to the present invention, but the ground noise is shielded from the low noise amplifier stage or the GPS engine module with a conductive material to prevent noise and oscillation of the antenna. In this case, the noise effect on the antenna can be reduced.

The non-square patch antenna of the ceramic dielectric block (substrate) and the integrated antenna module using the same according to the present invention can be mounted inside the user equipment as a miniaturized antenna or antenna module than the commercially available square patch antenna and the effect of improving reception performance Has

That is, if the non-square patch antenna according to the present invention having the characteristics of linear polarization is used, the reception performance can be compensated for by improving signal processing of an engine such as SIRstar 3, but weak in a multipath signal (noise). The same antenna can be used regardless of star polarization, and the antenna module can be mounted inside the terminal by miniaturizing the size of the antenna module compared to the conventional square patch antenna.

In addition, by forming a conductive pattern on the side of the dielectric block of the non-square patch antenna according to the present invention that is different from the horizontal and vertical, it has a circular polarization characteristic or a non-square dielectric block using a high dielectric constant of 30 or more and the length of the short axis When it extends more than 12mm, it can have circular polarization characteristics by forming a conductive pattern on top of the dielectric block.

 In addition, the non-square patch antenna of the ceramic dielectric block, which improves the characteristics of the linear polarization according to the size adjustment of the conductive pattern, is also a miniaturized antenna than the conventional square patch antenna, which can be mounted inside the user equipment and improves the reception performance. Have

In addition, if one or more grooves are formed in the conductive pattern of the dielectric top surface of the non-square patch antenna, the width of the conductive pattern is narrowed, so that the characteristics of other linearly polarized antennas in the 1.8 GHz band gradually move to the low frequency and the other low frequency. It is close to the linearly polarized antenna of, and its frequency, magnitude, and phase angle are 90 °, which shows circular polarization characteristics.

In particular, when the non-square patch antenna has a circular polarization characteristic, the reception characteristics of the conventional square patch antenna can be reduced while maintaining the advantages of circular polarization with low polarization loss. As manufacturing becomes easier, the disadvantages can be solved while taking advantage of the conventional square patch antenna.

Next, an integrated antenna module for implementing the non-square patch antenna on a low noise amplifier and a single PCB, and an integrated GPS antenna engine module for implementing the non-square patch antenna on a single PCB may also be a conventional square patch antenna. While maintaining the reception performance of the present invention, it is possible to solve the design problem of the conventional terminal by positioning the inside of the user equipment according to the miniaturization.

Furthermore, the integrated antenna module or the integrated GPS antenna engine module may not only be positioned parallel to the transverse direction at the upper end of the user equipment, but may be slightly bent or inclined depending on the design of the terminal.
