“…Partly due to their very low surface impedance, smaller losses, smaller dispersion and smaller propagation time have been reported showing that HTS patches are good candidates for current rapid communications. Furthermore, greater performances have been obtained using anisotropic dielectrics or substrate/superstrate configurations for HTS rectangular [10][11][12] and circular patch [13][14][15].…”

Effects of a superstrate layer on the resonant frequency and bandwidth of a high Tc superconducting (HTS) circular printed patch are investigated in this paper. For that, a rigorous full-wave spectral analysis of superconducting patch in multilayer configuration is described. In such an approach, the spectral dyadic Green's function which relates the tangential electric field and currents at various conductor planes should be determined. Integral equations are solved by a Galerkin's moment method procedure, and the complex resonance frequencies are studied with basis functions involving Chebyshev polynomials in conjunction with the complex resistive boundary condition. To include the superconductivity of the disc, its complex surface impedance is determined by using London's equation and the model of Gorter and Casimir. Numerical results are compared with experimental results of literature as well as with the most recent published calculations using different methods. A very good agreement is obtained. Finally, superstrate loading effects are presented and discussed showing interesting enhancement on the resonant characteristics of the superconducting antenna using combinations of Chebyshev polynomials as set of basis functions.

“…Two different cases have been investigated. First, the DRA without superstrate and then DRA with superstrate (Barkat, 2012;Yaduvanshi, 2012). Antenna gain was optimised for circular patch size and arrays (Guha et al, 2012;Petosa et al, 2003).…”

Antenna high gain, wide bandwidth, reconfigurability and compact design has been long requirements in the field of mobile communications and aeronautics. This paper experimentally investigates superstrate layer of arrays placed above the dielectric resonator antenna (DRA), which can largely enhance the gain of antenna. Experimental and simulated results of gain with and without superstrate have been investigated. The superstrate arrays placed on DRA has improved the antenna gain, i.e., 8.7 dBi to 12.27 dBi. The effect of high permittivity material has been studied for gain and bandwidth improvement. Barium strontium titanate (BaSrTio 3) mixed with silicon oil was used in DRA. Superstrate array have resulted into gain improvement to the extent of 28%. The design frequency was kept at 6.59 Ghz and verified theoretically using MATLAB. Height of substrate and dielectric constant affected the gain and bandwidth. Theoretical, simulated and experimental results have been compared and found in good agreement.

“…This papers looks into the possibility of monolithic behaviour of an active slot-ring antenna that is manifesting transmission, reception, and demodulation at the same time [16][17][18][19][20][21][22]. Specially, these papers demonstrate that (1) an active microstrip slotring antenna can act as a tracking demodulator while it is receives with excellent noise squelching capability, and (2) it can act as an aid to the development of a software defined discriminator which can adapt to different radio environment.…”

A Gunn mounted active microstrip slot-ring antenna (ASRA) has been investigated for the reception of FM microwave signal. Current well/valley phenomenon has been successfully utilized to demodulate the modulation information. The monolithic behaviour of an active slot-ring antenna as a lock-in amplifier, FM (Frequency Modulation) to AM (Amplitude Modulation) converter and square law detector has been demonstrated in this paper. Theoretical analysis coupled with experimental results has been presented. The proposed receiving scheme is unique in the sense that it does not require IF electronics for the purpose of demodulation. It also works well in a multi-channel environment due to the excellent noise-squelching property of an Injection Locked Gunn Oscillator.
