Abstract :
This paper discusses an antenna system composed of a fed metaspiral element and two dielectric slabs above the spiral. Analysis reveals that the slabs lead to an increase in the gain, in accordance with the formation of a narrow radiation beam. A gain of 6.5 dBi is obtained, which is 6.5 dB higher than the gain in the absence of the slabs.
