Dual band monopole antenna for wireless communication system
A dual band monopole antenna for Wireless local area network (WLAN) communication system is presented. The antenna has been designed with two meander branch monopole elements and the rectangular ground structure with simple configuration. The first branch is optimized by using a quarter wavelength of desired resonance frequency at 2.45 GHz. Meanwhile, additional branch of second branch brings resonance frequency of 5.8 GHz. This can easily suited by using 50 ohm probe feed with SMA connector. The proposed antenna is simulated by using Computer Simulation Technology (CST) software in order to simulate the return loss, bandwidth, gain, directivity, surface current and radiation pattern. The impedance bandwidth for return loss less than - 10 dB is 284 MHz and 267 MHz for first and second resonance frequency. In fact, second resonance can be adjusted by modifying the second branch length, LB1 with little effect on the first resonance.
