【Abstract】 A planar sleeve dipole collinear antenna array is presented in this paper, The proposed antenna is designed for operation at WLAN band(2.4GHz~2.485GHz),which can be used for point-to-point communication in wireless local area networks.The proposed antenna consists of two non coplanar planar printed dipole antenna elements, whic is used as a radiating element,arranged with a microstrip line to the balanced transmission line feeding, which are printed on the front surface of the substrate.The proposed antenna is simple in structure and easy to manufacture.Simulation results show that the Antenna VSWR≤1.5 impedance bandwidth is around 7.64%, with good horizontal omnidirectional radiation characteristics,and un-roundness is less than 1d B, the maximum gain is 5.6d Bi.更多还原
