Abstract

We present terahertz performance of integrated lens antennas consisting of a complementary log-periodic planar feed and a synthesized elliptical lens. The radiation pattern and the impedance of the planar feed are computed using the method of moments; the action of the lens is evaluated using the physical-optics approach based on the Huygens principle. In the frequency range from 0.6 to 5 THz measured antenna efficiency and radiation pattern correspond fairly well with the results of simulations approving this simulation technique as a reliable tool for the antenna design.
