A linearly polarized radial line slot antenna - IEEE ... Abstract: A design for linearly polarized radial line slot antenna (RLSA) is proposed. A novel slot arrangement is presented which couples to the rotationally symmetric guided waves to produce a uniform aperture distribution with linear polarization. Compact CPW-Fed Dual-Band Linearly and Circularly ... Figure 1 Potential radio filter locations. A compact dual-band linearly and circularly polarized monopole antenna employs an inverted L-shape and an asymmetric ground plane fed by a coplanar waveguide (CPW). The inverted L-shape strip produces an orthogonal component in the ground plane and monopole distinct from its original linear polarization (LP). A linearly polarised radial line slot array antenna for ...
A planar linearly polarized radial line slot array (RLSA) antenna is proposed to achieve a high gain with improved impedance matching and suppressed cross-polarization levels at a 270-GHz band.
