“…Presence of the metal at the substrate back side turns the antenna into the oscillatory contours with a high Q-factor. So far both the analytical theory of the log-periodic antennas [8], and numerical modeling [9] are developed. The distance between the antenna plane and metallization of the back side plays an important role.…”

“…In addition there is the difference between free space impedance and detector impedance result in high reflection losses. A bad coupling efficiency is consequence that that makes a detection of THz signals, even for high sensitive detectors like superconducting Hot-Electron Bolometers (HEBs), extremely difficult [1]. One solution to overcome the problems is to use an antenna structure.…”

In this paper a log-periodic terahertz antenna with metamaterial superstrate is proposed. A single-layer metamaterial structure, which utilized as a lens for the enhancement of gain of log-periodic terahertz antenna is used. The proposed metamaterial lens consist of an 8x8 matrix of Square Split-Ring Resonators (SRRs) and is placed above a probe-fed log-periodic terahertz antenna, resonating at 3.8 THz. The simulation result show that the proposed antenna achieves +9.991 dB gain at 4.521 THz, which is about +0.36 dB higher than the maximum gain of the conventional antenna. But proposed antenna provides a maximum gain enhancement of +1.11 dB at 3.846 THz frequency.

“…Log-periodic antennas have been used in wide frequency range of the electromagnetic spectrum [4][5][6][7][8][9]. In particular, integrated planar log-periodic antennas in the millimeter-wave and terahertz frequency bands have received much attention in order to be used in developing suitable and efficient signal sources in these frequency regions.…”

This paper presents a numerical simulation of a logperiodic antenna on an extended hemispherical lens. The overall performance of the antenna in terms of input impedance, radiation patterns, and radiation efficiency was studied and analyzed with the aid of a full-wave electromagnetic simulator. A hybrid method combining geometrical optics inside the lens and physical optics outside the lens was not necessary for calculating the far-field pattern of the antenna using this approach. This direct approach reduced the number of simulation iterations and was capable of characterizing the antenna characteristics accurately.
