Simultaneously transport multi-band ultra-wideband (MB-UWB) wireless signal and multi-level wired signal over single wavelength in wavelength-division multiplexing passive optical network (WDM-PON) is proposed, which can greatly improve spectrum efficiency and transmission ability of optical infrastructure.
In this paper, we propose a novel ultra-wideband planar inverse-F antenna (PIFA) using periodic metal patches ground plane. By applying the capacitive compensation for the input impedance of the PIFA in higher frequencies, the proposed PIFA has a working frequency band from 2.3 GHz to 9.0 GHz. The effect of geometric parameters of the periodic metal patches and antenna height on antenna performance...
