WebThe vertical and horizontal polarizations of the DRA are excited by CPW feed and slotline feed, which are switched by two p-i-n diodes. The design strategy is validated by simulations. The -10dB impedance bandwidth of the antenna is 20.4% for vertical polarization, and 18% for horizontal polarization, respectively. WebDec 1, 2014 · The characteristic impedance is established essentially by the width of the center conductor and the spacing between the conductor and the ground planes. For CPW, the characteristic impedance can typically be set between 20 and 250 ohms, compared to about 20 to 120 ohms for microstrip circuits and 35 to 250 ohms for stripline circuits. ef ef mマウントアダプター
