Design of 2.45GHz Planar Meander Dipole Antenna

In this study, we propose the simple structure design of planar meander dipole antennas with various shapes of stubs. The antenna which operates at 2.45 GHz is designed and fabricated successfully. The influences of stub parameters of the planar meander dipole antennas on the resonant frequency, bandwidth, and gain are described. We use IE3D software to design planar dipole antennas and choose the better parameters to manufacture the proposed antenna with triangular stub. The proposed antenna with the size of 38mmx22mm has resonant frequency of 2.45 GHz, bandwidth of 174MHz, return loss of-35.3dB and gain of 1.99dBi. The fabricated antenna can be used in 802.11b frequency band.
