Small antennaCurrent distributionUltra-wideband antennaBandwidth enhancementSlotted antennaA few years after the early investigation on ultra-wideband (UWB) wireless system, considerable research efforts have been put into the design of UWB antennas and systems for communications. These UWB antennas are ...
This reduces the connection problems between the antenna and the chip during the encapsulation of the tag with its support (ticket, etc.). A tag unit cost of 0.3$ is reported, making it quite a competitive solution with a more considerable investment on the reading system (2,000$ for the...
The basis of the transmitting station is a programmable radio frequency generator (R&S SMU200A vector signal generator). The generated signal was filtered using a band pass filter, amplified by a power amplifier, and directed to the directional antenna transmitter using a circular connector. The am...

To evaluate the design and performance of a communication system, it is desirable to evaluate it in realistic situations. The experiments can be performed directly in a vehicle, driving through different environments. However, this is a time-consuming and expensive task and it requires the presence...
A compact VHF/UHF ultrawideband discone antenna with consistent patterns is proposed in this article. The proposed antenna consists of a disk, a modified cone, an inverted cone, four shorting probes, and two sleeves. To improve the radiation angular dist
Finally, our derivations show that the square roots of the bounds are two to three orders of magnitude below the carrier wavelength for realistic system parameters. Keywords: 5G; wideband direct position estimation; distributed antenna array; Cramér-Rao bounds; mmWave; massive MIMO...

VHF/UHF/PS700/800MHz Multiband Combiner(SMA-female, IP60) In the wireless mobile phone communication system, the main function of the combiner is to combine the input signals of multiple frequency bands together and output them to the same indoor d...
The size of the antenna is 57 mm × 50 mm, and it operates in the frequency band of 0.89–5.02 GHz with almost omnidirectional radiation from the H-plane. The simulation is performed with a single transmitter and single receiver sensor. The pitch angle of the sensor is set to 30°, ...
