ANTENNA SYSTEM INCLUDING A CIRCULARLY POLARIZED ANTENNA
摘要
<p>An antenna system includes a circularly polarized (CP) antenna for receiving and/or transmitting a circularly polarized RF signal. The CP antenna includes a pair of radiating patches each having an elongated shape. An elongated axis is defined along a longest length of each of the radiating patches. The elongated axes are disposed generally perpendicular to one another to generate the circular polarization. A coplanar waveguide feeding element is disposed between the radiating patches for feeding RF signals from and/or to the radiating patches via electromagnetic coupling. A width of the slot of the coplanar waveguide is varied to provide impedance matching of the CP antenna with a transmission line.</p>
