This passive device lets you steer signal beams for over-the-air wireless test systems. Vaunix Technology, a manufacturer of modular RF/wireless test equipment, has introduced the LBM-7250-4 Lab Brick Butler Matrix, a beamforming tool that works with phased-array antennas to steer beams between transmitters and receivers. The Butler Matrix has four passive inputs and four outputs…

The long-wire dipole antenna is effective for low-frequency systems. Adding LC traps makes a single-band dipole antenna into a multiband unit. The historically significant long-wire dipole antenna may seem like an anachronism in these days of compact, highly mobile wireless devices operating in the gigahertz spectrum, but that’s not the case at all. Due to…

Wireless InSite 4.0 from Remcom lets you simulate wireless channel conditions and analyze them based on antenna movement.
