Objectives: To design high gain square slots loaded dual-band rectangular microstrip patch antenna having harmonic suppression capability and rectifier circuit (Rectenna (Antenna + Rectifier) for Radio Frequency Energy Harvesting (RFEH). Methods: To achieve the objectives, the square slots are loaded on the four corners of the rectangular microstrip patch in order to enhance the current distribution which resulted in improved impedance matching at desired frequencies with dual isolated bands. The proposed antenna is simulated in Computer Simulation Technology (CST) Studio Suite Three-Dimensional Electromagnetic Simulation (3DEM) software. A rectifier with an LC impedance matching network is designed, simulated, and optimized in Agilent Advanced Design System (ADS) software. Findings: The overall size of the proposed antenna operating at 2.49 GHz and 3.73 GHz (WiMax) is 57×48×2.5 mm 3 . The proposed antenna is assessed in terms of its simulated performance parameters: Return loss (S1,1), Impedance (Z1,1), Voltage Standing Wave Ratio (VSWR), Gain, Directivity, and Efficiency. The proposed antenna exhibits improved performance over the conventional rectangular patch antenna, in terms of (S1,1), Impedance (Z1,1) and Gain. The results obtained from the simulation indicate -35.47 dB and -37.42 dB of S1,1 at 2.49 GHz and 3.73 GHz respectively with the Gain of 4.74 dBi and 3.62 dBi respectively. Further, a rectifier circuit is proposed at 2.45 GHz. The complete rectenna system is simulated over a range of input power levels (1dBm-10dBm) for 4.7 kOhm load resistance. The simulated rectenna result presents the maximum output voltage of 3.34 V. Novelty and Applications: The proposed rectenna design with its harmonic suppression capability can be used for RFEH to drive the Internet of Things-Sensor Network (IoT-SN) and Wireless Sensor Network (WSN). The novelty of the proposed work is harmonic suppression capability. harmonic suppression capability is achieved by inserting the square slots at the four corners of the conventional square patch. https://www.indjst.org/

“…With a wide development in the wireless communications system and a large amount of devices that require a wideband of operating frequencies, the fifth-generation (5G) system has been occurred to increase the capacity, speed, energy efficiency, and reliability of the network [1]- [7]. Due to that development in the network, the needs for wide-bandwidth, light weight, low-profile, and small size antennas with stable radiation and good characteristics are in increasing [8]- [11]. Conventional printed antennas, on the other hand, may not meet such criteria as wideband, high-speed data transmission; steady unidirectional emission over a broad frequency range; and high gain [10], [12]- [14].…”

In this paper, a planar multiple input, multiple output (MIMO) dipole antenna for a future sub-6 GHz 5G application is proposed. The planar MIMO structure consists of 4 antenna elements with an overall size of 150×82×1 mm3. The single antenna element is characterized by a size of 32.5×33.7×1 mm3 printed on an FR-4 dielectric substrate with εr=4.4 and tanδ=0.02. The suggested antenna structure exhibits good impedance bandwidth equal to 3.24 GHz starting from 3.3 to 6.6 GHz with an S11 value of less than -10 dB (S11≤-10 dB) with antenna gain varying from 5.2 up to 7.05 dB in the entire band, which covers all the sub-6 GHz frequency band of the 5G application. Good isolation is achieved between the MIMO elements due to low surface waves inside the MIMO antenna substrate. The radiation of the MIMO antenna structure can be manipulated and many beam-types can be achieved as desired. The high-frequency structure simulator (HFSS) software package is used to design and simulate the proposed structure, while the CST MWS is used to validate the results.
