Terahertz dual-band dipole antenna with novel small flat quartz-copper reflector

In this paper, we have proposed a Terahertz dual-band dipole antenna with a novel small flat quartz-copper reflector. The dimensions of reflector, which is located at a 80 μm distance from antenna, are 300 × 160 × 45 μm. The antenna supports maximum gain of 12.4 dB at 5.2 THz frequency with two main resonant frequencies at 2.58 and 5.33 THz. Also, the proposed Terahertz antenna is used as an array element in linear and planar sets of elements, which are evaluated by using array method. An array Terahertz antenna, which has maximum gain of 18.7 dB at 5.2 THz, is proposed.
