Circular polarization (CP) requires the electromagnetic wave to rotate in polarization as it leaves the transmit antenna. Generating a rotating electromagnetic wave requires careful antenna design. If ...

SPX Communication Technology director of Advanced Antenna Systems Development John Schadler says circular and elliptical polarized DTV antennas are important tools in delivering a mobile DTV signal vi ...

So, in this simplified case, the direct signal arrives with its original rotation sense, say left-hand polarization, but the indirect signal arrives with right-hand polarization, and is rejected by ...

Neeraj Sood, a research at McMaster University‘s RFID Applications Lab, reports that the calculation of ERP and EIRP are independent of antenna polarization—which he says is related to the electric ...
