“…The design of printed antennas for wireless communication is still an important issue on the antenna field as can be seen on recent publications [1][2][3][4]. Finite-difference time-domain method (FDTD) is a widely used technique to perform time and frequency domain analysis for printed antennas.…”

“…In the latter scheme, the RF power is directly offered to radiating patches via a microstrip line 13,14 . In the former method, EMF coupling is made for transmitting power among the radiating patches and microstrip lines 15 . The 4 renowned feeding approaches were the “microstrip line, coaxial probe (both contacting schemes), aperture coupling and proximity coupling (both non‐contacting schemes)”; nevertheless, their patterns differ based on frequency 16‐18 .…”

The antenna design for a specified resonant frequency necessitates the computation of optimal values of different sizes. This is a harder task for microstrip patch antenna (MPA) since there is no precise numerical formula that leads to accurate solutions for designing these antennas. Presently, bio‐inspired approaches are widely deployed in numerous antenna designs and it has revealed an immense assurance in handling the rising necessities of antenna engineering for overall cost, reduced size, and enhanced performances. This work aims to introduce an optimal MPA design, where the antenna elements like patch length, patch height, substrate width, and substrate length are optimally tuned by a new hybrid optimization model. For this, a new hybridized model known as shark smell integrated EHO is proposed. Eventually, the primacy of the suggested model is scrutinized via varied assessments.

“…1 Microstrip patch antennas are the most popular structures for realizing CPA's. Microstrip patch CPA (MP-CPA) can be designed as a single feed [2][3][4][5][6][7][8][9] and dual (multiple) feed types. [10][11][12][13] Ferrite-based CPA's [14][15][16][17][18][19] provide a number of attractive features like beam scanning, 20,21 low radar crosssection scattering, 22,23 frequency tunability 24 and possible surface-wave reduction.…”

We propose an accurate analytical model for a circularly polarized antenna comprising a normally magnetized, grounded ferrite disk with a metalized top surface. The antenna is assumed to be excited by a conventional current probe. In the case of a thin ferrite disk, the electromagnetic fields of the dominant mode of the antenna do not vary in the direction normal to the disk. However, with increasing thickness of the ferrite disk, higher order modes start to affect antenna characteristics such as resonance frequency. This work presents an analysis of the structure that takes into account all higher modes of the antenna. To validate the theoretical calculations, HFSS simulations are performed. The antenna can be tuned by changing the magnetic bias field.
