In this paper a single fed microstrip patch rectenna for harvesting ambient radio frequency energy is presented. The antenna comprises of a clover shaped radiating patch operating at 2.4GHz ISM band. The rectifier circuit is placed in the same plane of radiating patch to minimize the overall antenna profile. The antenna is modelled and are fabricated on low loss roger dielectric substrate. Measured results show that the antenna achieves a peak gain of 7.19 dB in the operating ISM band with maximum RF conversion efficiency of 79%. The proposed antenna is suitable for wireless energy harvesting applications operating in ISM band.

Simulation Purpose

This article is about a single band microstrip patch antenna used for the 5G applications. And this antenna is suitable for the millimeter wave frequency. The patch antenna design consists of 2 E shaped slots and 1 H shaped slot. These slots are loaded on the radiating patch with the 50 ohms microstrip feed line. For the simulation purpose, Rogers’s RT5880 dielectric substrate with relative permittivity of 2.2 and loss tangent of 0.0009 is used. The design and simulation of the antenna is done using HFSS (High Frequency Structure Simulator) software. The results are simulated for the parameters Return loss, VSWR, 3D Radiation pattern. The proposed antenna has a return loss of -42.4383 at 59 GHz millimeter wave frequency.

Periodic Arrangement

The propagation of surface waves in the microstrip patch antenna proves to be proves to serious hindrance to radiation mechanism of the antenna. The periodic arrangement of shorting pins is embedded in the dielectric substrate at specific location to enhance the gain by around 4-5dB. The slotted perturbations have been done for achieving tri-band characteristics. The antenna is suitable for operation at three resonant frequency bands centered at 2.2421 GHz, 5.7632GHz and 7.7633GHz, which makes it suitable for WLAN applications.

Operating Bandwidth

Abstract Antenna studies on various wireless communication systems have been carried out by many academics. In this research, the omnidirectional microstrip patch antenna (MPA) is proposed, manufactured, and tested. The operating bandwidth of the antenna is quite suitable for the different applications. The proposed antenna fabricated on the flame retardant (FR-4) substrate with a volume of 75.85 × 57.23 × 1.59 mm3. Computer simulation technology (CST) studio used to design and simulate. Experimental results show that the return loss (RL), bandwidth (BW), voltage standing wave ratio (VSWR) and input impedance (Zin ) are -25.26 dB, 61 MHz, 1.12 and 54.46 Ω, respectively. The antenna operates at 2.42 GHz (from 2.39 to 2.45 GHz), which has good performance in the Wi-Fi, Bluetooth, and ZigBee communications.
