Abstract—Design of an Ultra Wide Band (UWB) filter over 3.1GHz to 10.6GHz using broad side coupled and spur lines in microstrip medium suitable for UWB communications has been presented in this paper. Parameters of broad side coupled lines have been appropriately chosen to achieve ultra wide band response. Spur lines have been incorporated at the input and output feed lines of the filter to imp...

UWB is a very attractive technology for many applications. It provides many advantages such as fine resolution and high power efficiency. Our interest in the current study is the use of UWB radar technique in microwave medical imaging systems, especially for early breast cancer detection. The Federal Communications Commission FCC allowed frequency bandwidth of 3.1 to 10.6 GHz for this purpose. ...

Wireless Sensor Network (WSN) has gained popularity in recent times in residential, commercial and industrial applications. Several wireless technologies have emerged ranging from short and medium distances. Bluetooth, ZigBee and Impulse Radio Ultra Wide Band (IR-UWB) are three short range wireless communications. There are several features of IR-UWB signals which make them attractive for a sho...

With rapid development of multi-core processor, the communication becomes a bottleneck increasingly. Traditional electronic connections face a serious complexity restriction. The network on chip has been a prevalent solution in the present. However using the recent technology (ultra-wide band interconnection) technology, the over-all performance including delay and throughput can achieve a new ...

UWB system that utilizes the unlicensed 3.1 – 10.6 GHz UWB band, as regulated in the United States by the Federal Communications Commission (FCC) Regulations. It is a trend that UWB and Bluetooth Technology will be combined together for developing a next-generation low-power, low-cost ad hoc networking solution that will expand Bluetooth technology’s current success. In this paper, we propose a...

Since the first Report and Order by the Federal Communications Commission (FCC) authorized the unlicensed use of ultra wideband (UWB) which must meet the emission masks on February 14, 2002 [1], both industry and academia have paid much attention to R&D of commercial UWB systems. Among UWB system design, the UWB antenna is the key component. Recently, a considerable amount of researches have be...

The Federal Communications Commission (FCC) agreed in February 2002 to allocate 7.5 GHz of spectrum for unlicensed use of ultra-wideband (UWB) devices for communication applications in the 3.1–10.6 GHz frequency band, the move represented a victory in a long hard-fought battle that dated back decades. With its origins in the 1960s, when it was called time-domain electromagnetic, UWB came to be ...

Recently, an ultra wideband (UWB) impulse radio draws much attention due to its potential low cost and low power consumption properties. The Federal Communications Commission (FCC) is currently working on setting emission limits that would allow UWB communication systems to be deployed on an unlicensed band following the Part 15 rules for radiated emissions of intentional radiators [1]. The UWB...

SUMMARY With the rapid progress of electronic and information technology, an expectation for the realization of body area network (BAN) by means of ultra wide band (UWB) techniques has risen. Although the signal from a single UWB device is very low, the energy absorption may increase significantly when many UWB devices are simultaneously adorned to a human body. An analysis method is therefore ...

A novel planar circular Apollonian fractal shaped UWB monopole antenna with band rejection capability is presented in this paper. The antenna performs satisfactorily in the frequency range 1.8–10.6GHz which gives a wide impedance bandwidth of 142% for VSWR within 2. The proposed antenna has the capability to reject the frequency band 5.125–5.825GHz assigned for IEEE802.11a and HIPERLAN/2. This ...
