摘要：
A stepped cylindrical antenna with a higher-order mode ring patch for wideband conical radiation pattern is proposed. To accomplish a low profile with wideband conical radiation characteristics, a stepped cylindrical monopole and a TM41 higher-order mode ring patch with four shorting pins are utilized. The proposed antenna has a monopole-like radiation pattern with a wide 10-dB return loss bandwidth of 11 GHz (2 GHz-13 GHz). It can cover various wireless services, such as wireless broadband (WiBro; 2.3 GHz-2.39 GHz), wireless local area networks (WLAN; 2.4 GHz-2.484 GHz, 5.15 GHz-5.35 GHz, and 5.725 GHz-5.875 GHz), digital multimedia broadcasting (DMB; 2.63 GHz-2.655 GHz), and ultra wideband (UWB; 3.1 GHz-10.6 GHz). The antenna has a height of only 0.12 lambda(0) at 2 GHz.
