Wide Band Monopole Antenna by Modified Ground of Coplanar Waveguide

Abstract

-The printed wide band monopole antenna having characteristics of dipole by modified coplanar wave guide(CPW) ground plane is presented. We are called a slot-arm printed monopole antenna and investigated the effect of the surface currents of the radiator on ground plane. The proposed antenna is treated as two asymmetric dipoles with the included angle of 90 o degrees which lie along Z-direction symmetrically. It is observed that the effect of the surface currents on the radiation patterns is similar to that of the corresponding dipole. The length and width of the ground plane correspond the radius and length of the dipole respectively. This approach is also valid to general printed monopole antennas. The simulation impedance bandwidth of the proposed antenna the range of 2.4 to 4. 그림 1 제안된 안테나의 설계 구조 Fig. 1 Structure of proposed antenna.

“…CPW 급전구 조를 이용한 광대역 특성과 더불어 다중공진 특성에 대한 연구가 각각 진행되어 왔다 [5][6][7][8][9], [10][11][12]. 특히 CPW 급전이 적용된 WLAN 시스템용 안테나에 대한 연구도 많이 이루어졌다 [13][14][15][16][17][18][19].…”
