In this paper, the authors presented to improve the bandwidth a W-slot technique is used, it is efficient to enhance the bandwidth of antenna. A broadband W-slot microstrip patch antenna is designed which attains a bandwidth of 22.74% at 10dB return loss with centre frequency of 4.5GHz and also it attains maximum directivity 8.78dBi. It is designed by cutting a W-slot into the patch of antenna, because of this resonant slot, the antenna gives broad bandwidth. A coaxial feeding technique is applied to microstrip patch antenna for impedance matching. This antenna is best suitable for C-band frequency spectrum. The proposed antenna is designed and simulated using IE3D software.
