“…The need for high-speed data rate is raising rapidly and will influence the wired communication capacity limit much quickly. The coming generation would require data rate better than 100Gbps, maintaining the necessity of investing additional frequency band for wireless communication [2]. A special frequency band ranging from 100 to 10k Gigahertz termed as the Terahertz band is considered to be essential in answering the increasing data rate demand [2].…”

“…Several kinds of research have been done tremendously for implementing microstrip antenna in optical frequency bands in the last few years [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Optical antennas have been implemented in various applications like single band operation [1], triple band [2], wide band [3]- [4], multiband application [5] as well as WBAN [7]- [8], Bio-sensing [11], dual polarization [12] etc. Due to low carrier mobility, the optical antenna suffers many challenges like deficient gain, harsh attenuation and extremely weak efficiency that affect the commercial implementation of THz wireless communication systems [6].…”

Future wireless communication needs antenna with multifunctional operation. This paper focuses on Terahertz Antenna that could be easily integrated with micro and nano devices. In this paper, an octagonal shaped Microstrip Fractal Antenna loaded with the EBG structure is designed for tri-band terahertz application. Triple band characteristic achieved by fractal radiating patch is loaded with Electronic Band Gap (EBG). The antenna features with total size of 700x900 µm 2 and resonates on three bands at 0.948 THz, 0.984 THz and, 1.040 THz. The result and performance indicates that the recommended antenna will be suitable for compact wireless devices and Monolithic Microwave Integrated Circuit (MMIC). All simulation work has been completed using electromagnetic software Ansoft High Frequency Structure Simulator (HFSS) and CST studio suite. The electromagnetic features like S11 parameters, VSWR, gain, efficiency and the radiation characteristics of suggested antenna are also examined. The simulation results show that this antenna has 9 dB realized gain at 0.948 THz resonating frequency.

“…Bansal et al performed simulations on a variety of antennas and proved that the planar slot butterfly antenna is the best choice for wide-band applications. They also designed a graphene-based band-gap butterfly terahertz antenna with a radiation efficiency of 71%, directivity of 18.194 dB and gain of 17.529 dB at a resonant frequency of 11.1 THz [21]. Thakur et al designed a novel photonic bandgap substrate microstrip patch antenna for cancer detection that resonated at 0.198 THz with a reflection coefficient of -68.53 dB and a gain of 3.43 dBi.…”

“…The butterfly antenna is one of the commonly used antennas for terahertz detectors. Compared with other terahertz antennas, the butterfly antenna has a simple structure and a stronger energy coupling ability [20,21]. The structure of a butterfly antenna is similar to a dipole antenna, so it can be fed by an optical hybrid [24].…”

Design of Terahertz Detection Antenna With Fractal Butterfly Structure

Terahertz (THz) technology can be widely used in radar, remote sensing, homeland security and counter-terrorism, high-secret data communication and transmission, atmospheric and environmental monitoring, real-time biological information extraction, and medical diagnosis. It is the frontier of current research. However, most of highly sensitive THz detectors work in a relatively narrow frequency range. It attracts great attention to design a high-gain terahertz antenna operates in a wide spectrum range. In this paper we propose a new structure of fractal butterfly antenna with high gain which can be used for broadband THz detection. This fractal butterfly antenna is constructed by independent fractal unit groups on butterfly antenna, which simplifies the antenna manufacturing process and reduces the manufacturing cost. The antenna can operate in the 0.1-10 THz frequency band, with impedance bandwidth of 85% resonated at 4.9 THz, return loss of as small as -33.59 dB, and maximum gain of 16.95 dB. Among the antenna with 3 to 4 fractal unit groups, the best operation band of the antenna is 6.2-6.4 THz. The proposed fractal butterfly antenna can effectively improve the performance of terahertz detectors, and provide the possibility for detection research in higher frequency bands.
