Abstract

An U-shaped patches loaded with dipole antenna designed for multiband antenna is proposed. The antenna can be reconfigured as single band at 3.5 GHz and dual-band frequencies at 2.4 GHz and 5.2 as required in WiMAX and WLAN applications. The length slot and length of U-shaped patch can be varied to adjust the desired upper frequency as well as the bandwidth. Moreover, the lower frequency also can be tuned by varying the dipole arms for both elements. The gains are performed 2.1 dB, 2 dB and 5.54 dB for single and dual band respectively with total efficiency is greater than 90%. The design methodology and antenna measurement results are both presented and discussed in this letter.
