“…Meta-material and electromagnetic surface design and development have contributed towards the evolvement of surface wave antenna which had effectively reduced the overall antenna size with total improvements in the overall performance. Various designs and shapes of EBG structures have been implemented on the metal surfaces of dielectric substrates in order to stop and propagate the surface wave [23]. Artificial periodic structures of EBG demonstrated the band stop features since no electromagnetic wave propagation is permitted.…”

An important issue in wireless communication systems, which is related to the antenna gain degradation in case of changing the main direction of the antenna radiation pattern, this variation is not approval in many communications systems. In order to improve antenna radiation performances, Electromagnetic band gap (EBG) - antenna with radiation pattern control capability is presented. Mushroom-like EBG structure for suppressing surface waves has been combined, with the switching diode to produce the radiation pattern control with improving antenna characteristics of gain, directivity and efficiency. EBG of several cells are surrounded the patch antenna and placed symmetrically for the two opposite sides, generating different radiation patterns control ability in both the elevation (E) (-20° < φ < 20°) and azimuth (Z) planes (−18° < θ < 18°). At the ground plane of antenna the diodes have been switched ON and OFF states, the EBG sector properties in stop band (connecting vias) and pass band (disconnecting vias) are altered. Using CST Microwave Studio (CST MWS) the results show the flexibility in radiation pattern control for the Z and E planes using only four diodes. Antenna directivity of 10 dBi, gain 9.86 dB and efficiency 96.5% at the operating frequency of 6 GHz, more results for all direction has been stated in Table1. Significantly, unlike a conventional beam steering, this method does not suffering from gain degradation and the main lobe gain is approximately constant for all steerig angles.

A novel compact Ultra-Wideband Multiple Input Multiple Output (UWB-MIMO) antenna with enhanced bandwidth is proposed. The bandwidth of the designed antenna ranges from 1 to 30 GHz which covers L, S, C, X, Ku, K bands and some part of Ka-band. A square slot & inverse L-shaped strip is used to improve the isolation amid antenna elements. The suggested antenna achieves Mutual Coupling and Envelope Correlation Coefficient below −17 dB and 0.15, respectively. MIMO performance parameters like Mean Effective Gain is around 0 dB, and Total Active Reflection Coefficient is less than −10 dB. The Channel Capacity Loss and Effective Diversity Gain are less than 0.3 bits/s/Hz and 9.2 dB, respectively. The radiation efficiency of the designed antenna is around 80% over the complete frequency range. The overall dimensions of designed antenna are 27 × 17 × 1.6 mm 3 .

The traditional method to achieve radar and IR bistealth is mainly to adopt the microwave absorbers coated by the metallic particles with high reflectivity in IR frequencies.

[26][27][28] Compared with traditional composite absorbers, metamaterial structures possess more freedoms for the realization of multispectral stealth. Recently, several metamaterial structures have been proposed to achieve multiple-spectral stealth performances. [29][30][31][32][33] In ref.[30], a dual-layer metasurface was adopted to realize microwave-IR bistealth performance, which can absorb the radar wave between 3 and 8 GHz and simultaneously realize a low IR emission of 0.2. Afterward, microwave transmission window and optical transparency have been integrated in single metamaterial. [31] However, these metamaterial-based stealth structures are typically rigid, which cannot be used for the applications on nonplanar surface. In ref.[34], a flexible microwave absorber with optical transparency has been proposed by employing indium tin oxide (ITO) film and polyvinyl chloride (PET) substrate, but the IR stealth property is disabled. As far as we know, there is no relevant report about the flexible and transparent microwave-IR bistealth materials.In this work, we propose a transparent and flexible microwave-IR bistealth metamaterial structure to avoid multispectral composite detection. Measured results prove that our structure exhibits high absorption larger than 90% from 7.7 to 18 GHz within a wide incident angle of ± 40°. Furthermore, a 10 dB radar cross section (RCS) reduction in 7.5-18 GHz is achieved when a metallic column is covered by our bistealth structure. In the IR atmosphere window, a low emission of 0.23 is obtained. In addition, the proposed metamaterial structure possesses excellent flexibility and optical transparency by utilizing ITO films and PVC substrates.A flexible and transparent microwave-infrared bistealth structure is proposed to avoid composite detection in the microwave and infrared bands. By combining intrinsic material properties with proper design, the proposed flexible metamaterial can simultaneously achieve high absorption in the microwave band, low emission the in infrared band, and optical transparency. The structure exhibits wide-angle (40°), broadband (7.7-18 GHz), and high-efficiency (>90%) absorption. Fu...
