The present invention relates to an antenna and an antenna module for receiving a satellite signal or a gap filler signal on the ground. More specifically, the present invention relates to a global positioning system (GPS), 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 a satellite signal or a gap filler signal, 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, which is shown in the top and bottom surfaces.

As shown in FIG. 1, the conventional patch pin type square patch antenna includes an antenna module 12 and a printed circuit board (PCB) 14 separated therefrom. The antenna module 12 has conductive materials coated on both ends of the dielectric block 11, a feeding pin 13 is positioned on an upper surface thereof, and one or more low noise amplifiers on the PCB 14. , 15) is formed 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 in order to implement circular polarization characteristics, and the feeding pin electrically connected to the conductive surface of the top surface passes through the dielectric block but It is formed to be electrically separated from the ground surface made of a conductive material.

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 should be secured with the sky cross section of the PCB to facilitate the reception of satellite signals. Is that. 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 reception in a shaded area is not possible. There is also the problem of instability. In addition, the square patch antenna has a characteristic of selectively receiving left hand circular polarization and right hand circular polarization when receiving a satellite signal with a circular polarization antenna. You need to redesign based on whether it is polarized or port polarized. In the case of designing a dual band antenna, the reception rate may be reduced due to the mutual interference effect according to the design of the left polarized wave receiving antenna and the star polarized wave receiving antenna.

On the other hand, according to the miniaturization trend, there have been attempts to use a smaller patch antenna or 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 patch antenna according to the present invention is another SMT type non-square patch antenna, which extends the conductive pattern 72 to both sides of the long side of the dielectric block 71 in the same manner as the patch antenna of the third embodiment. It is a structure. The conductive surface 72 of the upper surface of the dielectric block 71 of the patch antenna is electrically separated from the ground surface 73 made of a conductive material at the lower end, and electrically lowered to the ground conductive surface 73 at the lower end.

The non-square patch antenna of the ceramic dielectric block according to the fourth to sixth embodiments 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 conductive The non-square patch antenna of the ceramic dielectric block, which improves the characteristics of the linearly polarized wave according to the size adjustment of the 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. In addition, unlike the square patch antenna, it is possible to design a dual band. Particularly, when the circular polarization characteristic is used, the reception characteristics of the conventional patch antenna can be reduced while maintaining the reception characteristics of the conventional patch antenna, thereby enabling the transmission and reception of two or more channels at one frequency and taking advantage of the circular polarization with low polarization loss. .

5 shows a seventh 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, electrically connected to the conductive surface of the upper end of the patch antenna, and penetrates the upper and lower surfaces of the dielectric block 76, and the ground conductive surface of the lower end ( 79) 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, when the circular polarization characteristic is used, the reception characteristic of the conventional patch antenna can be reduced while maintaining the reception characteristic of the conventional patch antenna. Therefore, the timing adjustment can transmit and receive two or more channels at one frequency and take advantage of the circular polarization with low polarization loss. In addition, dual bands can be designed differently from square patch antennas.

The patch antenna in which the groove is formed in the conductive pattern is not limited to the above-described specific embodiments, and is applied to all of the second to sixth embodiments according to the present invention, thereby providing various types of non-square patches of the feeding pin type or the SMT type. Circular polarization characteristics can be realized with an antenna. 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.

Since the patch antenna according to the first to sixth embodiments implements a linear shape having a length of 13 mm and a width of 18 to 35 mm or 35 mm or more due to the width of the user equipment such as navigation, the user equipment Can be mounted inside. 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.

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.
