The Industrial Application of Single Layer Dual-Band Antenna with Simple Structure

A single layer dual-band antenna with simple antenna is designed in the article. The designed antenna contain U-shaped patch, feeding line, shorting pins, substrate and metal ground. U-shaped patch and the feeding line can realize dual bands characteristic. Finally, the proposed can work at 2.39GHz and 3.18GHz, and the realize gain are 2.63dB and 3.49dB.
