Design of Non-Uniform Bending Dual-Band Monopole Antenna

In this paper, a non-uniform snake-shaped dualband monopole antenna is studied and designed using the equivalent circuit method. Based on the traditional monopole antenna, the non-uniform bending technique is applied to effectively improve the miniaturization and multifunctionalization of the antenna. The simulation results show that the antenna can work in DCS1800 band and UMTS2100 band, and return loss less than -10dB at 1747MHz-1878MHz and 2078MHz-2335MHz, showing good operation performance.
