The present invention relates to an ultra-wideband antenna device and an antenna module including the same. More particularly, it relates to an antenna module including an antenna device including an antenna pattern suitable for ultra-wideband communication and a detachable antenna device.

With the recent development of the wireless communication industry, the development of an antenna capable of operating in a dual band or multiple bands is required. BACKGROUND ART Ultra wideband (UWB) wireless communication technology is attracting more and more attention in indoor short-distance communication because it provides a high transmission rate while using low power.

UWB communication technology is a technology that transmits information using a narrow pulse of 1 nsec or less instead of a radio frequency (RF) carrier wave. Transmission and reception are possible without interfering with the existing wireless communication system, and since the occupied bandwidth can be taken as an ultra-wideband, it is possible to obtain more than 100Mbps in transmission speed.

These features of UWB are attracting attention as a pivotal technology for the ubiquitous era, and a lot of research on the antenna field, which is the core technology of UWB, is in progress.

Accordingly, the need for the development of an antenna pattern for more efficient ultra-wideband communication and the development of an antenna module therefor is increasing.

10 is another view showing a cross-section of the ultra-wideband antenna device according to the present invention.

Preferably, according to FIG. 10 , the substrate 110 may include a first layer 110a, a second layer 110b, and a third layer 110c. The first layer 110a may be located on one surface of the second layer 110b, and the third layer 110c may be located on the other surface of the second layer 110b. The first layer 110a and the third layer 110c may be attached to the second layer 110b.

Due to the first layer 110a, the antenna pattern 120 and the second layer 110b of the substrate 110 may be spaced apart from each other by a predetermined interval. Through this, when electricity flows between the antenna pattern 120 and the second layer 110b, an electromagnetic field may be generated. It is possible to more effectively receive the ultra-wideband frequency by the influence of the generated electromagnetic field and the antenna pattern 120 according to the present invention. This may be the same for the third layer 110c, which is a configuration for separating the ground 140 and the second layer 110b.

The second layer 110b is a conductive layer, and it is assumed that any material that can be used by a person having ordinary knowledge can be used.

Preferably, the first layer 110a and the third layer 110c may have excellent mechanical durability along with insulating layer insulation. In the substrate 110 , the first layer 110a and the third layer 110c effectively block the electromagnetic field generated by the second layer 110b or set the antenna pattern 120 and the second layer 110b to a predetermined level. By spaced apart by an interval, effective reception for ultra-wideband frequencies can be achieved. However, in the case of the first layer 110a and the third layer 110c, physical resistance occurs during the insulation process, and in particular, the magnitude of the electromagnetic field transmitted to the second layer 110b or the continuously generated physical resistance lasts for a long time. As the temperature increases, the mechanical durability due to the first layer 110a and the third layer 110c decreases, which may lead to a problem of insulation deterioration.

Therefore, the durability of the substrate 100 is that the entire structure is supported by the insulating layers of the first layer 110a and the third layer 110c. This has to be kept high.

Preferably, the first layer 110a or the third layer 110c is an insulating layer, and may include 30 to 40 parts by weight of an insulator based on 100 parts by weight of the epoxy acrylate resin represented by Formula 1 below.

[Formula 1]

On the other hand, the insulator is specifically silicon dioxide (dioxide), Al ₂ O ₃ , Ta ₂ O ₅ , TiO ₂ , CrO ₂ , HfO ₂ , Y ₂ O ₃ Oxides such as PMMA and TEOS, silicon nitride (nitride) , tantalum nitride, nitrides such as titanium nitride, oxynitrides such as SiOxNy, high dielectric constant (ε≥30) metal oxides such as BaSiTiO ₃ , BaTiO ₃ , and SrTiO ₃ , xerogels and their It may consist of a combination, multilayer, or mixture.

[Production Example]

With respect to 100 parts by weight of the epoxy acrylate resin represented by Formula 1, 35 parts by weight of an insulator, 5 parts by weight of a curing agent monoamine, and 100 parts by weight of a solvent ethyl acetate (Ethyl Acetate) were mixed to prepare an insulation coating composition. The insulator was used by mixing Ta ₂ O ₅ , TiO ₂ , CrO ₂ , and Y ₂ O ₃ in the same ratio. The insulating coating composition was coated on one surface of the substrate to a thickness of 2 nm to form a uniform layer as a coating layer.

[Comparative Example 1]

A layer was prepared through a coating method in the same manner as in Preparation Example except that the epoxy acrylate resin was excluded from the insulation coating composition.

[Comparative Example 2]

A layer was prepared through a coating method in the same manner as in Preparation Example except that the insulator was excluded from the insulation coating composition.

[Experimental Example 1: Evaluation of Insulation Properties]

The surface resistance to the substrate was measured using a high resistance tester of Mitsubishi, JPN, Japan.

(O: surface resistance value more than 3x1010, ㅿ: surface resistance value lxlO9 to 3xl010, x: surface resistance value less than 1xlO9) have. Therefore, when the layer is formed according to the composition, it is possible to secure the desired excellent insulating properties, so that it can be applied to the first layer 110a or the third layer 110c.

[Experimental Example 2: Insulation film reliability evaluation]

In order to evaluate the peel-off characteristics, PCT evaluation was performed using a PCT chamber manufactured by Hirayama, Japan. The above-described PCT evaluation was performed under conditions of a temperature of 121° C., a pressure of 2 atm, and a relative humidity (RH) of 100%. In addition, in order to evaluate the peel-off characteristics, constant temperature and humidity evaluation was performed using COSMOPIA manufactured by Hitachi, Japan. The above-mentioned constant temperature and humidity evaluation was conducted under the conditions of 85 ℃ temperature and 85% relative humidity.

production example Comparative Example 1 Comparative Example 2 Peel-off or not (PCT Test) X X О Peel-off or not (constant temperature, constant humidity test) X О О

(О: The coating layer is detached from the substrate. X: The coating layer is not detached from the substrate) In order to check whether the coating layer is detached under the conditions of use of the substrate, a peel-off test was performed. As for peel-off, it can be confirmed that the coating layer according to the preparation example of the present invention does not detach, and in the case of the comparative example, Comparative Example 1 did not detach on the PCT test, but it can be confirmed that it detaches in the constant temperature and humidity test. Therefore, it can be confirmed that, when the first layer 110a or the third layer 110c is applied according to the composition, the durability of the entire substrate can be increased with excellent durability along with insulation.
