Multi-objective Integrated Modeling of Resource Utilization For Stability of Port Operating System

Abstract

In this paper, a novel heart-shaped UWB antenna with quintuple band-notched characteristics is proposed and demonstrated. The proposed antenna has a small size of 26 mm by 34 mm and it consists of a heart-shaped radiating element, a microstrip feed-line and ground planes with round corners. The measured results show that the proposed antenna has an ultrawideband(UWB) frequency range from 2.23 to 10.75 GHz with VSWR (voltage wave standing ratio) less than 2, except in the frequency bands of 2.31 to 2.62 GHz, 3.35 to 3.79 GHz, 5.14 to 5.9 GHz, 7.12 to 7.76 GHz and 8 to 8.43 GHz for filtering some existing narrowband communication systems such as WLAN (wireless local area networks), WiMAX (worldwide interoperability for microwave access), downlink of X-band satellite communication and ITU (International Telecommunication Union) 8-GHz band, respectively. The simulated and measured results of proposed antenna are in good correlation. It also has good omnidirectional radiation patterns and gain characteristics in the required frequency bands.
