“…However, the antennas in [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] do not have the band-notched function to avoid the interference. Recently, some antennas with band-notched function have been reported [22][23][24][25][26][27]. Unfortunately, the size of the antennas is still relative large in [22][23][24][25][26][27].…”

Abstract-A compact band-notched ultra-wideband (UWB) spatial diversity antenna is presented in this paper. The antenna is fabricated on an FR4 substrate and consists of two tapered microstrip feeding lines and two radiating elements. The wireless local area network (WLAN) for IEEE 802.11a operating in 5.15-5.825 GHz band-notched function is achieved by introducing two slits in the radiators as λ/4 resonators. The simulated and measured results show that the presented antenna has a broadband impedance bandwidth which covers UWB band and also has a band-notched characteristic. Additionally, the antenna has a good transmission coefficient better than −15 dB across the UWB. The radiation patterns, peak gain, and envelope correlation coefficient are measured and discussed.

Abstract-A MIMO/Diversity antenna with triple notch characteristics is proposed in this article. The proposed antenna has triple notches in the WiMAX band (3.3-3.6 GHz), WLAN band (5-6 GHz), and X-band satellite communication (7.2-8.4 GHz) band. Defected Ground Compact Electromagnetic Band Gap (DG-CEBG) is a design used to accomplish band notches. Defected ground planes are utilised so as to achieve compactness in conventional EBG structures. The proposed WiMAX band, WLAN band, and X-band satellite communication band DG-CEBG structures show a compactness of around 46%, 50%, and 48%, respectively, over a conventional EBG structure. In these structures, decoupling strips and a slotted ground plane are used to enhance the isolation between two closely spaced UWB monopoles. The individual monopoles are 90 • angularly separated with a stepped structure which helps to reduce mutual coupling and also contributes towards impedance matching by increasing the current path length. |S 21 | or mutual coupling is found to be less than 15 dB over the whole UWB frequency range. The Envelope Correlation Coefficient (≤ 0.5) is within the acceptable limits over the whole UWB frequency range. Notched frequency depends on the parameters of DG-CEBG structures; when there is a change in these parameters notch frequency is also changed. A low cost FR-4 substrate with thickness (h) = 1.6 mm, permittivity (ε) = 4.4 and loss tangent (δ) = 0.02 is used for the proposed antenna, and it has a compact size of 58 × 45 × 1.6 mm 3 .

“…This solution is new and unique by making it possible to produce antennas using a conductive layer of prepared silver nanoparticles and consequently, it is possible to make additional reproductions without changing the geometry of the antenna. Silver nanoparticles are applied to the PET substrate using inkjet printing technology so as to incorporate them directly into plastic casings used for the protection of wearable electronics [5][6][7][8][9]. The presented solution for printing the antenna by means of the inkjet printing on the basis of silver nanoparticles is unique because a low weight flexible microstrip antenna is produced using a polymer stabilized silver nanoparticles ink obtained by the solvothermal synthesis method that has not been used in any previous research.…”

This work describes the use of inkjet printing technology to fabricate a flexible microstrip antenna. The antenna is printed on a flexible PET foil (Polyethylene terephthalate) using silver nanoparticles. Silver nanoparticles were synthetized by the solvothermal precipitation technique. The diameter of the prepared silver nanoparticles ranges from 20 to 200 nm measured with the help of the SEM analysis. In addition, the ink formulation for printing of a homogenous and electrically conductive layer was further prepared using silver nanoparticles. The printed antenna operates in two frequency bands of 2.02 GHz (-16.02 db) and 2.3 GHz (-19.33 db). The antenna is flexible and weigh is only 0.208 g and is suitable for electronic devices of a very low weight, such as wearable electronic devices.
