A coplanar waveguide (CPW) fed rectangular loop antenna with dual frequency characteristics applicable Wi-Fi bands is presented. The studies to calculate the dependency of frequencies on the antenna structure is carried out using ANSYS HFSS. From this, the antenna is optimized to have an enhanced gain of ~ 8 dBi at 2.45 GHz and 3.83 dBi at 5.32 GHz. The radiation characteristics of the antenna are studied and the radiation pattern confirms the monopole characteristics at both the frequencies. The optimized antenna performance is confirmed by measurements using Vector Network Analyser. Since energized using coplanar waveguide the proposed antenna finds applications in Microwave Monolithic Integrated Circuits (MMIC) also.

An antenna is an integral component in a wireless communication system. The choice of the antenna geometry of these systems depends on the preferred specifications. Depending upon the variation in the geometry and feeding technique, the performance of the antenna can be modified. For any communication system design an antenna with a better transmission range, improved reflection and radiation characteristics at the designed frequencies is desired. An asymmetric coplanar strip fed antenna is designed and analyzed in this paper. This structure gives better performance compared to microstrip and coplanar waveguide (CPW) fed omni-directional antennas. The proposed antenna is compact with reduced complexity, providing appreciable gain. A monopole antenna system with a metamaterial ground plane on the same plane is proposed. This antenna operates in the 2.45 GHz Wi-Fi band. The radiating element and the metamaterial ground plane are optimized for the best performance of the antenna system. For optimum performance of the antenna, open loop resonator is also studied as the ground plane. Miniaturization is achieved with metamaterial ground plane without changing the characteristic of the monopole antenna structure. The monopole antenna with the metamaterial ground plane is found to be compact with resonance at 2.45 GHz offering a 2 : 1 VSWR bandwidth of 217 MHz. The radiation pattern of the designed antenna is omni-directional with a gain of 3.124 dBi at the resonant frequency. The antenna is designed and optimized using ANSYS HFSS 14. The optimized antennas are fabricated using FR4 substrate and are experimentally validated using Vector Network Analyzer E5080A.

Present work proposes an Asymmetric Coplanar (ACPW) fed antenna providing wide band and omnidirectional radiation. Gain enhancement is achieved by the introducing perturbations on the shorted ground plane. The proposed antenna offers a 2 :1 VSWR bandwidth of 741 MHz at 5.2 GHz with the enhanced gain of 6.4 dBi. The parametric analysis and optimization of the antenna is done by using ANSYS HFSS. Optimized prototype is analyzed experimentally using Keysight E5080A Vector Network Analyzer. The proposed antenna will have wide range of applications in different wireless communication systems

Summary form only given. Strong light-matter coupling has been recently successfully explored in the GHz and THz [1] range with on-chip platforms. New and intriguing quantum optical phenomena have been predicted in the ultrastrong coupling regime [2], when the coupling strength Ω becomes comparable to the unperturbed frequency of the system ω. We recently proposed a new experimental platform where we couple the inter-Landau level transition of an high-mobility 2DEG to the highly subwavelength photonic mode of an LC meta-atom [3] showing very large Ω/ωc = 0.87. Our system benefits from the collective enhancement of the light-matter coupling which comes from the scaling of the coupling Ω ∝ √n, were n is the number of optically active electrons. In our previous experiments [3] and in literature [4] this number varies from 104-103 electrons per meta-atom. We now engineer a new cavity, resonant at 290 GHz, with an extremely reduced effective mode surface Seff = 4 × 10-14 m2 (FE simulations, CST), yielding large field enhancements above 1500 and allowing to enter the few (<;100) electron regime. It consist of a complementary metasurface with two very sharp metallic tips separated by a 60 nm gap (Fig.1(a, b)) on top of a single triangular quantum well. THz-TDS transmission experiments as a function of the applied magnetic field reveal strong anticrossing of the cavity mode with linear cyclotron dispersion. Measurements for arrays of only 12 cavities are reported in Fig.1(c). On the top horizontal axis we report the number of electrons occupying the topmost Landau level as a function of the magnetic field. At the anticrossing field of B=0.73 T we measure approximately 60 electrons ultra strongly coupled (Ω/ω- ||
