A coaxial-fed hexagonal dielectric resonator antenna (HDRA) producing circular polarization is investigated experimentally. Circular polarization is achieved by exciting the orthogonal HE 11β¦ modes of the HDRA in phase quadrature. The return-loss, impedance, and radiation characteristics are studied
## Abstract Experimental results are presented for the dielectric and radiation losses from flexible circular PTFE waveguides in the Qβband. The dielectric and radiation losses from rod and tube waveguides were found to depend strongly on the design parameters, such as the operating frequency, area
