Among different matching topologies, the series inductive scheme demonstrated the best performance for X-band to DC energy conversion.

The recently published IEEE Std 802.15.6™-2012 includes IR-UWB and FM-UWB technologies. The IR-UWB transceivers for BANs are based on the transmission of a single and relative long pulse per symbol (new paradigm in UWB) or a concatenation or burst of short pulses per symbol (legacy), while FM-UWB transceivers are based on the concatenation of a CP-2FSK signal and a wideband FM signal.

The design is based on increasing the effective capacitance of the original quarter-wavelength combline resonator by engineering the loading interdigital capacitance at the open end of resonator, thus achieving the same resonant frequency by using a shorter physical length. The resonator structure is designed to confine the electric field in a smaller real estate to decrease losses and coupling interference with adjacent components.

To improve the skirt selectivity and out-of-band performance, two identical high-low impedance stubs are introduced into the design, without changing any resonant characteristic of the filter.
