본 논문에서는 연방 통신위원회의 UWB(Ultra-wideband)주파수 대역(3.1~10.6[㎓])을 만족하는 새로운 디스크 모노폴 안테나를 설계하였다. 제안된 안테나는 광대역화를 위해 원형 패치 안에 직사각형 슬롯을 삽입하였으며, 부분 접지기법을 이용하여 후면 방사에 대한 간섭을 줄였다. 제안된 안테나는 유전율이 4.4, 두께가 2㎜인 FR-4 기판으로 설계하였으며, UWB 전대역에서 2이하의 VSWR을 만족하였고 -10㏈ 이하의 양호한 반사 손실을 나타내었다. In this paper, a novel Disc monopole antenna is designed satisfying UWB(Ultra-wideband) frequency bandwidth(3.1~10.6[㎓]) of FCC(Federal Communication Commission). The proposed antenna of UWB application consists of putting circular patch on a FR-4 substrate with digging rectangular slot on circular patch and obtained to decrease the back radiation by a partial ground plane for extending bandwidth. The proposed antenna is designed on FR-4 substrate with a relative dielectric constant 4.4 and thickness of 2㎜. The designed antenna shows that VSWR is below 2 and has good return loss below -10㏈ over the bandwidth.

In this paper, we present a design of circular monopole antennas in a wire grid form. The circular plate antenna is one of the monopoles with very wide bandwidth characteristics. Due to its simple form, it is useful in ultrawideband applications. When it is to be used in low-frequency devices, the plate form may be too unwieldy due to its weight and wind resistance. To solve the problem, we propose a design of circular monopole antennas in a wire grid form.
