A new type of fractal-shaped microstrip patch antenna for ultra-wideband (UWB) applications and with sufficient rejection in the WLAN band is presented. The radiating patch is placed on a 1.6 mm thick low-cost FR-4 epoxy substrate and is fed using a symmetric coplanar waveguide. The size of the proposed antenna in terms of wavelength is 0.189λ 0 × 0.197λ 0 . A sectorial-circular slot in the patch is used to create WLAN band notch. An impedance bandwidth of 11.76 GHz (from 2.19 to 13.95 GHz) is achieved, along with achieving WLAN band rejection from 4.67 to 6.21 GHz. Nearly omnidirectional radiation pattern with the maximum gain of 5 dB in the passband is achieved. In the rejection band, the gain drops to −3 dB. The simulated results are verified against experimental data and a good agreement between the two sets of data is seen. The proposed antenna covers both the unlicensed 2.4 GHz band and the UWB.

This work presents the two port ultra-wide band MIMO antenna with novel isolation structure and dual band RF Rectifier for 3.3 GHz and 4.65 GHz frequencies for RF energy harvesting applications. The anticipated antenna is systematically examined within the ultra-wideband (UWB) range from 3.1 GHz to 10.6 GHz design frequency with four different steps: Antenna 1, Antenna 2, Antenna 3 and Antenna 4 (optimal design) are chosen for comprehensive study. A unique isolation structure was developed between two identical elements separated by 10 mm, resulting in an enhanced isolation of −23.5 dB at 3.15 GHz, −27 dB at 5.8 GHz, −28 dB at 9.26 GHz and greater than −34 dB at 7.5 GHz. The suggested antenna resonates at UWB band and have fractional bandwidth of 118.66 % and a peak gain of 4.1 dB at 3.15 GHz, 3.68 dB at 5.8 GHz, 6.4 dB at 7.5 GHz and 3.2 dB at 9.26 GHz has been obtained. Radiation efficiencies of 92.5 %, 95 %, 90 % and 84.5 % at 3.15 GHz, 5.8 GHz, 7.5 GHz and 9.26 GHz were obtained respectively. The recommended MIMO performance is simulated using HFSS in terms of ECC, DG, MEG and CCL. The results adhere to specified requirements and confirmed by experimentation. An HFSS simulated dataset of reflection coefficient is used as input for the various ML algorithms namely, Support Vector Machine (SVM), Ensemble, k-nearest neighbors’ algorithm (KNN) and Gaussian Process Regression (GPR) models are trained with 80 % of the data and testing with 20 % of the data. The test results are compared and corresponding performance values of MAE, RMSE, MSE & R 2 are 0.00029, 0.00197, 3.87e−6 and 1.0 validation results and corresponding test results are 0.00031, 0.00229, 5.20e−6 and 0.999. Finally, the proposed dual band rectifier with a shorted stub is tested for harvesting applications at 3.3 GHz and 4.65 GHz frequency and it attained RF to DC conversion efficiencies of 69 % and 55.40 % respectively.

The ﬁltering antenna provides both radiation and ﬁltering features and is an important component for the RF front-end of wireless devices. The main function of a ﬁltering antenna is to reject out-of-band signals, thus reducing the interference from adjacent channels. The aim of the present work is to design a 2.6 GHz microstrip ﬁltering antenna for 4G and 5G global mobile services. The ﬁltering antenna is designed using a hairpin bandpass ﬁlter integrated with an elliptical microstrip aerial. Good impedance matching is obtained by using appropriate dimensions of the hairpin bandpass ﬁlter. The 10 dB return loss bandwidth of the ﬁltering antenna is approx. 5.7%, with the maximum gain for the elliptical ﬁltering antenna of approx. 2.2 dB. Good agreements between the measured and simulated results are obtained for the proposed ﬁltering antenna and the bandwidth covers almost the entire 2.6 GHz band.
