A hemispherical dielectric resonator antenna excited by a microstrip feedline through a narrow slot in a thick ground plane is studied theoretically and experimentally. A numerical method based on a combination of the spectral Green's function, modal Green's function, and the method of moment is use

## Abstract In this paper, a simple design cylindrical dielectric resonator antenna (CDRA) with wide apertureβcoupled for broadband applications has been proposed. For improving impedance matching, microstrip feedβline was designed as a forkβlike to obtain two resonant modes excitation and lead to
Figure 6 Discrepancy between measured and actual disturbance positions obtained with the sensor is approximately 5 m for 200 m of sensing fiber. We believe that the measurement accuracy can be improved by developing a better signal processing technique and by using polarization-maintaining fiber.
