Equivalent Circuit ModelMatlabPatch AntennaAlthough the square patch antenna is a well known printed circuit antenna, there are gaps in the publications that prevented accurate design for practical dual polarization patch antennas. This paper describes (without gaps) the steps that allow rapid design ...
Further, the antenna is remodeled by placing a defect on the copper ground plane in order to generate an additional resonant mode which also improves the impedance bandwidth at low resonant modes. The antenna equivalent circuit is derived by following relevant conformal FDTD numerical procedure ...
Equivalent circuit model of a patch antenna. A rectangular microstrip radiator can be modeled as an open cavity bounded by the patch and the ground plane. Assume the relative dielectric constant to be εr and the substrate thickness to be h,k then the total electric field in the leaky ...
patch antenna merged, for the first time, with a metasurface absorber acting as artificial ground. A methodology for the unit-cell design of the metasurface is proposed followed by an equivalent circuit model analysis, which makes it possible to transform a low-loss (tanδ=0.0015) unit-cell ...
equivalent circuitA simple but accurate equivalent circuit of an aperture-coupled cavity-fed microstrip patch antenna is developed. It consists of ideal transformers, admittance elements, and transmission lines, and the related circuit-element values are computed by applying the reciprocity theorem and ...
This paper introduces a new configuration of compact, triangular- and diamond-slotted, microstrip-fed, low-profile antenna for C/X band applications on polytetrafluoroethylene glass microfiber reinfo...
With the help of circuit simulation and full wave simulation, the equivalent circuit model of the antenna is established. The simulated and measured results show that the impedance bandwidths for VSWR less than 2 of the proposed dual-polarized antenna with a profile of are 27.3% (3.29-4.33 ...
The equivalent circuit model is applied to analyse and design the proposed antenna. This antenna exhibits monopole-like radiation pattern in the lower band and patch-like radiation pattern in the upper band. Simulation and experimental results are used to verify the theoretical prediction. 展开 ...
The antenna will use a resonant patch with two orthogonal axis of symmetry such as a circle or square placed centrally above the cross aperture which again will have two orthogonal axes of symmetry. FIG. 1 shows four feeds 6, 7, 8, 9, over the cross aperture and an equivalent circuit fo...
摘要: of the antenna is less than -10 dB between 3.06 and 5.49 GHz and the radiation patterns are found to be relatively constant throughout the band. A coaxial feed with Gaussian modulated pulse is used for this antenna.关键词: antenna radiation patterns equivalent circuits microstrip antennas...
