    This paper presents a lightweight antenna for wireless communication systems. The proposed antenna has been designed to be a dual-band and dual-polarized antenna by using a right-angled slot structure fed a by microstrip line. The designed antenna is composed of three right-angled slot radiators on the ground plane. The first two radiators are right-angled slots of similar scale which are added to generate circular polarization at 4.95 GHz, while the last one has been designed for linear polarization at 2.45 GHz. Furthermore, in order to achieve dual-band operation and dual polarization with good matching, a special arrangement is proposed. The results of simulation and measurements such as return loss, axial ratio, and radiation patterns are shown at the resonant frequencies of 2.45 and 4.95 GHz. Details of the experimental results are presented and discussed. In addition, the presented antenna can operate and cover the applications of a wireless local area network (WLAN IEEE 802.11 a/b/g/j/n). © 2014 Institute of Electrical Engineers of Japan.

    A novel compact and light weight antenna for dual band and dual polarized right angle slot antenna fed by micorstrip line use in wireless network technology is designed. The antenna composed of three right angle slot radiators on a same ground plane. Two right angle slots in the same size are arranged for circularly polarized at frequency 4.95 GHz and the other one is designed for linearly polarized at frequency 2.45 GHz. Therefore, in order to achieve dual band and dual polarized with good matching, the technique of arrangement is recommended. The simulation results of return loss, VSWR, gain, axial ratio, and radiation patterns are shown at resonant frequency 2.45 GHz and 4.95 GHz. ©ICROS.
