Abstract

Microstrip patch antennas are widely used in modern day communication devices due to their light weight, low cost and ease of fabrication. In this paper, we have designed and fabricated a Cross-Slotted Ring Microstrip Patch Antenna and array at 2.4 GHz for Wireless Local Area Network (WLAN) applications using Computer Simulation Technology, CST. The designed antenna consists of rectangular radiating patch on Rogers RT5880 substrate and is excited by using coaxial probe feeding technique. The cross- slotted ring has been designed on top of the radiating patch to improve bandwidth. The simulation and measurement results of the cross-slotted ring patch antenna are in close agreement with each other. The simulated and measured S-parameters shows -21dB and -15.6 dB at 2.4 GHz respectively. Then, the antenna has been formed into lx4 array in order to observe its beamforming capability. The proposed antenna array is suitable for 802.11b/g/n Wi-Fi standard which is proposed to be used for IoT.

2.4 GHz无线应用中交叉开槽环形贴片天线阵列的波束形成能力

微带贴片天线由于其重量轻、成本低、易于制造等优点，在现代通信设备中得到了广泛的应用。在本文中，我们利用计算机仿真技术(CST)设计并制作了一种用于无线局域网(WLAN)应用的2.4 GHz交叉开槽环形微带贴片天线和阵列。设计的天线在Rogers RT5880基板上采用矩形辐射贴片，采用同轴探针馈电技术进行激励。为了提高带宽，在辐射贴片的顶部设计了交叉开槽环。交叉开槽环形贴片天线的仿真结果与实测结果吻合较好。在2.4 GHz频率下，模拟s参数为-21dB，实测s参数为-15.6 dB。然后，将天线组成lx4阵列，观察其波束形成能力。该天线阵列适用于拟用于物联网的802.11b/g/n Wi-Fi标准。
