Formulation of resonant frequency for compact rectangular microstrip antennas

Abstract

The approximate equations to calculate the resonant length of various compact rectangular microstrip antennas like, C‐shaped, H‐shaped, and rectangular ring microstrip antenna, are proposed. The error in the calculated resonance frequency is <5%. © 2006 Wiley Periodicals, Inc.

An Application of ANN Model with Bayesian Regularization Learning Algorithm for Computing the Operating Frequency of C-Shaped Patch Antennas

“…It is clear from the Table 3 that our operating frequencies results are generally in very good agreement with the simulation. To demonstrate the validity and accuracy of the ANN-BR model, the model was tested against simulation data given elsewhere [3]. The test results are tabulated in Table 4.…”

“…By using the substrate materials with high dielectric constant, the smaller antennas can be achieved but this gives rise to decrease the bandwidth and efficiency performances [2]. C-shaped patch antennas (CPAs) formed by slot-loading technique are widely used owing to having better characteristics such as wideband and miniaturized structure [3][4][5]. In analysis of the traditional PAs techniques such as cavity model [6] and transmission line model [7] are used.…”

“…There exist several approaches which vary in accuracy and computational efforts have been proposed to analyze and design PAs. The most widely used can be listed as formulation methods [3][4][5] and artificial intelligent systems (AIs) [10][11][12][13][14][15]. Formulation methods are commonly derived with the aid of the optimization ASTESJ ISSN: 2415-6698 algorithm such as genetic, particle swarm, differential evolution etc.…”

H- Shaped Stacked Patch Antenna for Dual Band Operation

“…4(a), in which∆L 2 and ∆C 2 are the additional inductance and capacitance respectively which originate due to introducing the two notches and R H is resonance resistance after cutting the notches into the patch. The value of R H can be calculated using Equation (5) and the additional inductance and capacitance can be given as [16] …”
