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. The filter is physically compact and has wide passband. An ultra-wideband UHF filter having bandwidth more than 20% is designed using full-wave solving software and fabricated in microstrip technology. Experimental results are in good agreement with the theoretical and simulated results.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129855794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper a reconfigurable software defined radio (SDR) transmitter specifically designed for IR communication tests is presented. The prototype offers the possibility to transmit arbitrary 4-ary modulated impulses with 1 GHz bandwidth over four channels in the frequency range from 6 GHz-10 GHz. For generation of intermediate frequency (IF) signals a subsampling concept with a multi-Nyquist digital to analog converter (DAC) and a field programmable gate array (FPGA) has been employed. Pseudo-coherent signals are synthesized at radio frequency (RF) by utilizing a mixer with a local oscillator (LO) frequency locked to the LO of the DAC. A comparison of theoretically derived signals and measurements shows that both are in close agreement.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130062237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods must be developed to protect UWB systems that are exposed to this negative impact of the narrowband interference (NBI). Most proposed solutions have been developed for coherent and transmitted-reference receivers but a very few of these principles are eligible with the noncoherent energy detector (ED) receiver. The work presented thereafter aims at proposing a novel method to identify and mitigate the narrowband interference in ultra wideband transmissions. We use an efficient algorithm with a modified but still simple energy detector, and the performance of the method is evaluated by means of computer simulations.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130471423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.
