Abstract
Low side lobe level with low cost multilayer antenna for IEEE 802.16e applications such as WiMAX over industrial, scientific, and medical (ISM) band (5.725 – 5.875) GHz was presented shows high gain of 12.60 dB and fort-to-back ratio (F/B) of 18.55 dB with bandwidth around 163 MHz. The proposed multilayer antenna with reflector (MAWR) composed of a single plane feeding patch printed on Rogers RT/ Duroid 5880 substrate, covered with four Rogers RO6006 superstrates while a reflector layer located under feeding patch. Adding superstrate and reflector layers caused performance improvement by increasing gain and bandwidth with input reflection coefficient and side lobe level reduction. Computer Simulation Technology (CST) Microwave Studio was used as simulation environment.
