Abstract :
A broadband microstrip patch antenna with double-layer substrate structure is proposed in this paper. The proposed antenna is excited by a novel L-shaped coplanar waveguide (CPW) and the main motivation for this work is to achieve wide bandwidths for Wibro (2300-2390MHz), Bluetooth (2400-2484MHz) and S-DMB (2605-2690MHz) operation. The experimental result shows that the proposed antenna with three resonant frequencies at 2.25, 2.53 and 2.93GHz, provides 32.6% impedance bandwidth (2.18GHz~3.05GHz) with return loss less than -10dB. The size of the antenna is 70*70*8mm. The study shows maximum achievable gain of about 8.4dBi and gain variation of 1.4dBi between the frequency ranges of 2.18GHz to 3.05GHz. Details of this broadband antenna design is presented and discussed.
