“…From the antenna geometry, it is seen that the two layers of the dielectric material as substrate and superstrate have been used in the antenna design whose length ( L 1 ) and width ( W 1 ) are 4000 µm each. The dielectric attenuation constant for a single layer of the substrate ( α d ′) is calculated by using the following formula .

α_{normald}' = π \frac{ε_{normale} - 1}{ε_{normalr} - 1} \frac{ε_{r}}{ε_{e}} \frac{tan δ}{λ_{g}} Np / unit length and α_{dTotal} = 2 α_{normald}' L_{1}

SUMMARY In this paper, a probe‐fed rectangular microstrip patch antenna with metallic frequency selective surface as superstrate has been analyzed and simulated at terahertz frequency. In addition to this, a novel technique has been proposed to predict the directivity of the antenna at submillimeter and terahertz waves where far‐field measurement is a challenging task. Moreover, the effect of the size of the frequency selective surface array and the ground plane on the directivity of the antenna has been discussed. The concept of using two lateral sidewalls to improve the electrical performance of the antenna is also presented. The theoretical analysis has been supported by two different commercially available 3D electromagnetic simulators: (i) CST microwave studio (CST, Framingham, MA, USA) based on the finite integral technique; and (ii) Ansoft hfss (Ansoft Corporation, Pittsburgh, PA, USA) based on the finite element technique. Analytical and simulated results are comparable with each other. Copyright © 2011 John Wiley & Sons, Ltd.

“…In recent years, high-frequency technology has attracted the attention of a large number of researchers. This is due to its important role in the fields of biological imaging and sensing, detection of explosives, spectroscopy and high-speed wireless communications [1][2][3][4]. At the same time, with the increasing complexity in the electronic systems and in order to reduce the costs, manufacturers have moved towards integrated circuits technology [5,6].…”

The time‐domain simultaneous signal and noise analysis of mm‐wave/THz devices (diode) modelled as a transmission line is considered. For such devices, stochastic telegrapher's equations of a transmission line are extracted assuming a quasi‐transverse electromagnetic mode. Since the analytical solution for these equations does not exist, numerical analysis of such equations is presented here in millimetre‐wave and terahertz frequencies. These equations are analysed with two different numerical methods in the time domain, namely the finite‐integration technique and the Method of Moments. A semi‐distributed model in the ADS commercial software is used to validate the numerical results. Non‐linear effects in the model are introduced to simulate a Schottky diode. Using this non‐linear model signal and noise behaviour in a Schottky diode is analysed, resulting in the simulation of the noise figure of the device.

“…From the energy perspective, the infrared and microwave technology on both sides of terahertz band has been highly mature in the electromagnetic spectrum between electron and photon, whereas the terahertz technology is almost empty. This is because in this frequency band, it is not entirely suitable for optical theory to deal with, nor is it entirely applicable for microwave theory to study [1].…”

“…The advantages of terahertz wave lead to high research implication in many fields. In communication, terahertz wave exhibits higher frequency than millimeter wave terahertz wave, so terahertz wave can provide wider bandwidth and transmit more information when employed in communication [1]- [3]. As stimulated by the further maturity of terahertz technology, the application of terahertz technology in high-speed and short-range wireless communication has been achieved.…”

The study on terahertz radiators will not only boost the development of theoretical research, but also raise severe challenges to solid-state electronics and circuit technology. In the present paper, the transmission characteristics of microstrip-slot coupling structures are primarily studied in 1-3THz band.Based on the single-layer dielectric structure, a double-layer dielectric microstrip-slot coupling structure with air as one layer is presented. It is reported that adding air layer based on the single-layer structure helps reduce the loss. Besides, given the factors of Engineering processing, the structure of three-layer media is also proposed; it is found that the structure of three-layer media still has exhibits transmission loss when the engineering realization is satisfied. However, this study suggests that the loss of the three-layer structure is higher than that of the two-layer structure, whereas the effect is better than that of the single-layer structure.INDEX TERMS Terahertz, multilayer structure, transmission characteristics, odd mode, even mode.
