Abstract :
A technique for construction of a millimeter-wave antenna has been developed based on the high permittivity LSE-NRD guide technology. The novelty of the present technique lies in use of a simple radiator, which consists of tapered dielectric strip with the length of about a guided wavelength and has the broad radiation pattern. The folded planar antenna for the wireless LAN systems and car warning sensers has been fabricated by locating the radiator in the focal point of the cylindrical parabolic reflector. A pencil beam pattern with the half-power beam widths of 2° in H-plane and 7° in E-plane can be obtained.
