摘要：

Integrated antenna-source (IAS) systems depends on techniques that reduce the complexity of traditional separated antenna-source systems. The IAS has a number of advantages such as compactness, simplicity, and efficiency. However, the ultra wide-band (UWB) gain of IAS is low since the integrated system employs omni-diretional antennas. Here, we propose a new IAS system. We increase the size of capacitance and implement a smooth transition structure in the new system. As a result, the proposed IAS shows a UWB gain of 0.68. It is more than double compared to that of conventional IAS systems. The radiated electric field measured at 4 m from the system has a peak value of 80.8 kV/m and a center frequency of 350 MHz. The radiated power density decreases by half when the radiation angle is changed from 0 degrees to 60 degrees.
