RF Multi-Functional Input-Reflectionless Dispersive-Delay Structure With Sharp-Rejection Filtering Using Channelization Techniques
PublicationA class of RF multi-functional input-reflectionless dispersive-delay structure (DDS) with linear-type in-band groupdelay variation and sharp-rejection bandpass-filtering capability is reported. It exploits a two-branch-channelized/balanced-type circuit with similar low-order reflective DDS units inside its channels, which are connected through input/output 3-dB quadrature wideband couplers. The adopted DDS unit is based on a coupledresonator...

BADANIE ZABEZPIECZEŃ MODUŁÓW WYTWARZANIA ENERGII ZGODNIE Z WYMAGANIAMI KODEKSU SIECI RfG
PublicationCelem zapewnienia bezpieczeństwa systemu elektroenergetycznego w ramach systemu wzajemnie połączonego, niezbędnym jest ustalenie jednakowych wymogów mających zastosowanie do modułów wytwarzania energii. W tym celu ustanowiony został kodeks sieci RfG dotyczący wymogów w zakresie przyłączania jednostek wytwórczych do sieci. W pracy przedstawione zostały wymagania kodeksu sieci RfG wobec zabezpieczeń źródeł wytwórczych. Na stanowisku...

Dual polarization antennas for UHF RFID readers
PublicationThis paper presents various concepts of switching polarization in patch antenna dedicated for UHF RFID readers. Proposed designs allow for switching between linear and circular polarization. The first design does not require electronic switching as the polarization can be changed by choosing one of two available feeding terminals. Two remaining designs use PIN diode or FET SPDT switch.
