摘要

现代无线通信系统要求天线紧凑，带宽宽，可以与其他电路元件集成。宽频带下回波损耗低的微带天线是正确的选择。本文提出了一种优化的矩形槽超宽带八角单极天线。该天线采用缺陷接平面和辐射贴片中心的矩形槽进行优化。用50欧姆阻抗的微带馈电来激励天线。在整个范围内，天线的驻波比小于2。该天线适用于无线局域网，雷达成像，遥感应用。

An octagonal monopole antenna for ultra wide band applications

Modern wireless communication systems require compact antennas with wide band width that can be integrated with other circuit components. Microstrip antennas with low return loss over wide band width are the correct choice. In this paper an optimized octagonal monopole antenna with a rectangular slot for Ultra Wide Band (UWB) range is proposed. The proposed antenna is optimized with defected ground plane and a rectangular slot in the center of the radiating patch. A microstrip feed of fifty ohms impedance is used to excite the antenna. VSWR of the proposed antenna is less than two for the entire range. This antenna is useful for WLAN, radar imaging, remote sensing applications.
