摘要: According to the analyses of the moding properties of circular groove guide, the guide dimension for single mode operation is determined. Our results show that circular groove guide has the advantage of wide band.关键词: Theoretical or Mathematical/ circular waveguides waveguide theory/ ...
Mi-Wave’s 282 Serieslinear to circular polarizersconvert input linear signals to circularly polarized output signals. The circular polarization sense (RHCP or LHCP) and center frequency should be specified at the time of order. Note:Our website contains just a few types of Linear Polarizers we ...
Using a coplanar waveguide (CPW) feed with a short-circuiting stub, the fed circular slot antenna for W-band operation is presented. The obtained results show that the impedance bandwidth, which is determined by 10 dB return-loss of the proposed slot antenna, can reach to 21% with the ...

A W-band (75-110 GHz) Gunn oscillator realized with a resonant cap configuration in a circular waveguide is described. Output powers of more than 10 dBm and a mechnical tuning range of 8 GHz are obtained with the new ascilltor mount over the frequeucy range 75-90 GHz. These results ...
The complex permittivity measurements of a PTFE in the direction tangential to a plate are performed to investigate accuracy of a cut-off circular waveguide method in W band by using four resonators. Moreover, the novel 100GHz grooved circular empty cavities and newly developed excitation cable ...
In this paper, a novel dual-band substrate integrated waveguide (SIW) filter with perturbed circular cavity is presented. By introducing a pair of metallic via perturbations combining different angle of feeding lines, five resonant modes TM\n\nare perturbed to design the proposed filter. Two types...
When used with a certain type of antenna that conforms to indoor environments, such as a conventional waveguide and multilayer planar antennas [13,14,15], they can obtain a wide or broad IBW, omnidirectional radiation pattern, high antenna gains and a wide CP band. However, they suffer from...
