“…1,2 The unique combination of these attributes made FPRA a subject of intensive research, which has focused on improving their performance. [3][4][5][6][7] A FPRA is comprised of a resonant cavity formed between two parallel plane mirrors-a fully reflecting mirror that is typically a metal ground plane, and a partially reflecting mirror that is made out of dielectric slabs 8,9 or 2D/ 3D periodic structures.…”

This paper presents a quasi-analytical technique to design a continuous, all-dielectric phase correcting structures (PCSs) for circularly polarized Fabry-Perot resonator antennas (FPRAs). The PCS has been realized by varying the thickness of a rotationally symmetric dielectric block placed above the antenna. A global analytical expression is derived for the PCS thickness profile, which is required to achieve nearly uniform phase distribution at the output of the PCS, despite the nonuniform phase distribution at its input. An alternative piecewise technique based on spline interpolation is also explored to design a PCS. It is shown from both far-and near-field results that a PCS tremendously improves the radiation performance of the FPRA. These improvements include an increase in peak directivity from 22 to 120 (from 13.4 dBic to 20.8 dBic) and a decrease of 3 dB beamwidth from 41.5 to 15 . The phase-corrected antenna also has a good directivity bandwidth of 1.3 GHz, which is 11% of the center frequency. V C 2015 AIP Publishing LLC.

“…In this way, it is well understood that the directivity enhancement mechanism of a microstrip antenna must be studied at the submillimeter and terahertz frequency to make it compatible to the terahertz communication systems. To enhance the directivity of the elementary dipole and microstrip antenna in the microwave frequency regime of the spectrum, highly reflective surfaces as superstrate is widely used , and it indicates that such kind of structure is equally suitable at the terahertz frequency. Moreover, there are enough evidences to support the propagation of the terahertz electromagnetic wave over the metallic‐clad low dielectric permittivity substrate materials .…”

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.

“…It has aroused more and more attention [2][3][4] for several years, which results in some interesting conclusions based on different viewpoints and analysis models such as leaky wave model [5][6][7][8][9][10], EBG defect model [11][12][13][14][15][16], FP cavity model [1,2,17,18], equivalent refractive lens model [19,20] have been attained and proposed. A summary of this type of antenna is also presented in [19,21].…”

Abstract-In this paper, the transverse equivalent network (TEN) model based on the transmission line theory is employed to analyze and calculate the far-field radiation properties of the Fabry-Perot Resonator (FPR) antenna with perfect magnetic conductor (PMC) ground plane in detail, then the comparative study of the radiation property of FPR antenna with PMC and PEC ground plane is presented. The closed-form expressions for the radiated fields, field peak values, pattern beamwidths and pattern bandwidth of this type of antenna in the E-and H-planes are derived, respectively. The results demonstrate that in theory the radiation property of FPR antenna with two kinds of ground plane is not the same unexpectedly. An interesting characteristic of this type of antenna is that when the PMC acts as the antenna ground plane, the beamwidth and bandwidth of the antenna is increased by a factor of two in general cases, while its peak value of far field is the same as that of the conventional antennas of this class having PEC ground plane. Some results are validated through fullwave simulations of an actual antenna. The original results obtained here lead to a design method for getting the maximum directivity and keeping the bandwidth of this kind of resonant antenna, which is of great significance for antenna designing.
