The digital channelized receiver is an efficient way to deal with broadband signal. In this paper, one kind of channelized algorithm based on poly-phase filter is derived. We discussed the realization of a multi-channel receiver applied to the software radio platform in details. The computing core of this platform is FPGA. Simulation result of the channelized receiver is given. The test in practical...
This article presents the multi-input multi-output (MIMO) antennas with the element of a polygonal loop. The antenna element consists of a half-wavelength inverted-U loop microstrip and an L-shaped ground plane, and has a low profile of 0.08λ0 at 2.6GHz. Due to the two coupling-currents, which are caused by radiation emission and conduction emission and are 180° out of phase, field cancellation clearly...
This study firstly investigates a printed rectangular monopole antenna with notched ground plane. The planar monopole was printed on an FR4 substrate and placed above a rectangular notch cut in a finite ground plane edge. By suitable separations of the patch from the left and right edges of the notch, two derived resonant modes are added to the lower band and upper bands respectively. Therefore, the...
