“…RFIDs are operated within various microwave frequency bands; among these, UHF-RFIDs provide specific significance in wireless technology. In the RFID domain, reader construction in the UHF band is widely used due to the long read range (1 m-10 m), and this is mostly applicable in container tracking, pallet tracking, parking lot access, and electronic toll fee collection [10][11][12][13][14][15][16]. e construction and design of RFID antennas comprise challenges such as size, read range, and bandwidth coverage.…”

The proposed RFID reader antenna progressed with perfect electric conductor (PEC) as the radiating element and FR 4 as the substrate to achieve circular polarization, enhancement in bandwidth, and read range. The design presents a CPW feed RFID antenna for near-field reading applications, between the range of 903 MHz to 929 MHz. The operating frequency of the proposed design is 900 MHz, axial ratio of the model is less than 3 dB, impedance bandwidth is 256 MHz, and axial bandwidth is 36 MHz, proving to be adequate for near-field RFID reader applications such as item-level tagging and smart shelf. The proposed antenna model is realized with fractal structure to achieve miniaturization. The developed antenna is optimized using EM software for numerical analysis. The designed antenna is fabricated, and the prototype is characterized in terms of dielectric constant and loss tangent. The obtained results indicate high correlation with simulation results.

“…There are multiple ways by which one can enhance the IBW and gain includes the use of low permittivity substrate [13], by increasing the height (thickness) of substrate material [14], by embedding the proper slot at appropriate location in patch as well as in ground termed as Defected Ground Structures (DGS) [15][16], using PBG or EBG [17], the introduction of parasitic patch in the same plane with the main radiating patch along the radiating or non-radiating edge and in a different plane [18][19], superstrate [20] etc.…”

In this article the radiation performance of coaxial feed dual band dual print microstrip patch antenna using Electromagnetic simulation tool IE3D (Integral Equation Three-Dimensional) and CST-MWS (Computer Simulation Technology Microwave Studio) is offered and discussed. The attempt is made to compare the antenna parameters such gain, impedance bandwidth and radiation pattern from both the Electromagnetic Software. It is observed that both the software has their own pros and cons. However, the features available from the CST make it more feasible in comparison to IE3D. With the presented geometry a wide impedance bandwidth 5.62GHz (1.86-7.48GHZ) with sustained gain is achieved. The antenna radiation parameters are also found as desired. A brief comparison of various EM software is also given for the interest of the readers.

“…Many techniques may be found in the open literature to overcome this issue of low impedance bandwidth. Some of the impedance bandwidth enhancement techniques include multilayer stacking arrangement of the antenna [3], the introduction of a low permittivity substrate [4] in-between ground and patch, different types of slots and strips introduced on the top metallic patch or/and on the ground [5][6], the arrangement of multiple resonators in the same plane coupled directly with each other or/and by some gap [7][8], etc. All these techniques have their own pros and cons and can be applied at the system's convenience.…”

The design evolution and investigation of a semi-elliptical patch antenna having a slot in the ground plane is discussed in this paper. The proposed prototype delivers extraordinarily wide impedance bandwidth ranges from 10.5GHz to 40.0GHz and beyond. In the design of this antenna, a semi-elliptical patch is fed by a tapered feed line, which is backed by a squareshaped ground plane that is slotted with an elliptical-shaped slot. The antenna is small in size, with a dimension (L*W*h) of 39.0mm × 39.0mm × 1.59mm and gives desired radiation characteristics including the stable radiation pattern. The gain value within the impedance bandwidth region is almost steady and positive. The antenna performance is optimized with CST Microwave Studio 2017. The designed antenna will be a useful candidate for the recent 5G technology as this technology requires a very high bandwidth with sustained gain to transmit the data at a high speed.
