도 1은 본 발명의 일 실시예에 따른 광대역 안테나의 구성을 나타내는 사시도이다. 1 is a perspective view showing the configuration of a broadband antenna according to an embodiment of the present invention.
도 1에 도시되는 바와 같이, 본 발명의 광대역 안테나는 기판(110), 및 상기 기판(110) 상에 형성되는 방사 패치(130)를 포함한다. As shown in FIG. 1, the broadband antenna of the present invention includes a substrate 110 and a radiation patch 130 formed on the substrate 110.
본 발명의 광대역 안테나는 상기 기판(110)이 높은 비투자율 및 상대적으로 낮은 비유전율을 갖는 것을 특징으로 한다. 구체적으로 설명하면, 본 발명의 광대역 안테나에 포함되는 기판(110)은 비투자율이 비유전율보다 상대적으로 큰 값을 나타내며, 바람직하게는 비투자율/비유전율 ＞ 1 인 관계를 갖는다. 그러나, 비투자율/비유전율의 값은 약 1이 될 수도 있다. 즉, 비투자율/비유전율 ≥ 1 인 관계를 갖을 수 있다. 한편, 상기 (비투자율/비유전율)의 값이 클수록 대역폭이 넓고 소형화된 안테나를 얻을 수 있으며 이에 대해서는 후술하도록 한다. The broadband antenna of the present invention is characterized in that the substrate 110 has a high relative permeability and a relatively low relative dielectric constant. Specifically, the substrate 110 included in the broadband antenna of the present invention has a relative permeability that is relatively greater than the relative dielectric constant, and preferably has a relationship of relative permeability / relative dielectric constant> 1. However, the value of relative permeability / dielectric constant may be about one. That is, it may have a relationship of relative permeability / relative dielectric constant ≥ 1. On the other hand, as the value of the (permeability / relative dielectric constant) is larger, a wider bandwidth and a smaller antenna can be obtained, which will be described later.
상기 특징을 가지는 기판(110)은 페라이트(ferrite) 자성체로 구현될 수 있으며, 페라이트 자성체와 낮은 비유전율을 갖는 유전체와의 혼합물로도 구현이 가능하다.The substrate 110 having the above characteristics may be implemented as a ferrite magnetic material, and may be implemented as a mixture of a ferrite magnetic material and a dielectric having a low relative dielectric constant.
기판(110)의 전체 크기는 80mm×80mm×6mm 일 수 있으나, 이에 제한되는 것은 아니며, 구현하고자 하는 안테나의 크기 및 그 위에 형성되는 방사 패치(130)의 크기에 따라 적절하게 선택될 수 있다. The overall size of the substrate 110 may be 80 mm × 80 mm × 6 mm, but is not limited thereto, and may be appropriately selected according to the size of the antenna to be implemented and the size of the radiation patch 130 formed thereon.
방사 패치(130)는 기판(110) 상부에 형성되며, 전도성 금속으로 구현될 수 있다. 그 크기는 50mm×50mm 일 수 있으나, 이 역시 이에 제한되는 것은 아니다.The radiation patch 130 is formed on the substrate 110 and may be formed of a conductive metal. The size may be 50mm × 50mm, but this is also not limited thereto.
본 출원인은 본 발명에 따른 광대역 안테나의 성능을 실험하기 위해, 다양한 비유전율과 비투자율을 가지는 기판들을 이용하여 그 반사손실, 정재파비(VSWR), 및 이득을 비교하여 보았다.Applicant compared the return loss, standing wave ratio (VSWR), and gain by using substrates having various relative dielectric constants and relative permeabilities to test the performance of the broadband antenna according to the present invention.
제 1 기판으로는 비유전율이 1, 비투자율이 9인 기판을 이용하였고, 제 2 기판으로는 비유전율과 비투자율이 모두 3인 기판을 이용하였으며, 제 3 기판으로는 비유전율이 9이고 비투자율이 1인 기판을 이용하였다. As the first substrate, a substrate having a relative dielectric constant of 1 and a relative permeability of 9 was used. As a second substrate, a substrate having both relative dielectric constant and relative permeability of 3 was used. As the third substrate, the relative dielectric constant of 9 was used. A substrate having a permeability of 1 was used.
도 2 내지 도 4는 상기 3 가지 기판을 이용하여 안테나를 구현한 경우의 반사손실, 정재파비 및 이득을 각각 나타낸다.2 to 4 show return loss, standing wave ratio, and gain, respectively, when the antenna is implemented using the three substrates.
도 2 내지 도 4의 그래프 상에서 도면부호 (1), (2), (3)은 각각 제 1 기판, 제 2 기판, 및 제 3 기판을 사용하여 안테나를 구현한 경우의 특성을 나타내는 것이다. Reference numerals (1), (2), and (3) on the graphs of Figs. 2 to 4 show characteristics when the antenna is implemented using the first substrate, the second substrate, and the third substrate, respectively.
도 2 내지 도 4에서 알 수 있는 바와 같이, (비투자율/비유전율)의 값이 가장 큰 제 1 기판이 넓은 대역에서 가장 낮은 반사손실을 나타내며, 전 대역에 걸쳐 고루 낮은 정재파비를 보이며, 전 대역에서 고루 높은 이득을 보여 3 개의 기판들 중 최적의 성능을 보이는 것을 알 수 있다.As can be seen in Figures 2 to 4, the first substrate having the largest value of (permeability / relative dielectric constant) shows the lowest return loss in the wide band, evenly low standing wave ratio over the entire band, It can be seen that the optimum performance of the three substrates is shown by showing a high gain evenly in the band.
한편, 이하의 표 1은 상기 3 가지 기판을 이용하여 안테나를 구현하였을 경우 그 안테나의 크기, 대역폭, 및 이득을 비교한 것이다. Meanwhile, Table 1 below compares the size, bandwidth, and gain of the antenna when the antenna is implemented using the three substrates.

패치 사이즈(Patch size) 라는 것은 각 기판 상에 형성되는 방사 패치(130)의 크기를 나타내는 것으로 공기 중에서의 파장(lamnda0)에 대한 비율로서 나타내었다. The patch size refers to the size of the radiation patch 130 formed on each substrate and is expressed as a ratio with respect to the wavelength (lamnda0) in the air.
표 1에서 알 수 있는 바와 같이, 제 1 기판, 제 2 기판, 및 제 3 기판이 유사한 안테나 크기 및 최대 이득을 보이는 한편, 가장 높은 (비투자율/비유전율) 값을 보이는 제 1 기판이 다른 기판들에 비해 월등히 향상된 대역폭 특성을 보인다.As can be seen from Table 1, the first substrate, the second substrate, and the third substrate have similar antenna sizes and maximum gains, while the first substrate with the highest (permeability / dielectric constant) value is the other substrate. Compared to other devices, the bandwidth characteristics are significantly improved.
이상에서 설명한 바와 같이, 기판 및 상기 기판 위에 형성되는 방사 패치를 포함하는 광대역 안테나에 있어서, 비유전율에 대한 비투자율의 비가 높은 페라이트 자성체와 같은 물질 또는 혼합물 등을 기판으로 사용함으로써, 안테나의 소형화와 동시에 월등히 향상된 대역폭 특성을 얻을 수 있게 된다. As described above, in a broadband antenna including a substrate and a radiation patch formed on the substrate, the antenna can be miniaturized by using a substance or mixture such as a ferrite magnetic material having a high relative permeability ratio as a substrate. At the same time, significantly improved bandwidth characteristics can be obtained.
