Abstract: In this paper multiband U-shaped patch antenna is designed for C and S band applications. L-shaped slots introduced in the two corner of the patch antenna which improves the antenna performance to operate with multiband of frequencies and also provide notch characteristics at 3 GHz. The patch is operated at four bands of frequencies. Operating frequency of the antenna is from 1 to 10 GHz. FR-4 substrate with 4.4 dielectric constant is used for antenna design. Simulations results are carried out by ADS tool. U-shaped patch with L slot and stub which is placed on the defective ground plane achieves return loss upto -47dB at 1.7 GHz and 5 GHz. The gain of the patch antenna is about 6 dB.

Keywords: U Shaped Antenna, FR 4 Substrate, Multiband, ADS Tool, L Shaped slot, Notch Characteristics.
