In this paper, the near-field characteristics of an L-probe patch antenna on a finite ground plane are presented. The objective is to thoroughly comprehend the effects of the L-probe on the performance of the patch antenna based on the computation using the finite-difference time-domain method...
Microwave near-field distribution of the GPS patch antenna was visualized by a thermo-elastic optical indicator microscopy (TEOIM) technique at 1.575 GHz. Visualization of the antenna radiation is realized to describe the electromagnetic field intensity and distribution ...
We can create a microstrip antenna forNear Field Communication(NFC) by creating an antenna consisting of two separate patches. A layer of foam separates these patches. Various degrees of freedom are available to the designer when constructing the patch antenna, including the relative permittivity of ...
In recent years, the evolution of vehicular safety systems and the burgeoning field of autonomous vehicles have underscored the need for advanced radar solutions tailored to these specific applications. By addressing this need, this paper presents an innovative radar antenna design—the Edge Truncated ...

Equation 11.37 provides a reasonable first-order estimate of the input impedance of the patch antenna near resonance. Note that there are many other simple models that also provide a first-order estimate of the input impedance. Often, the designer must either fabricate and perform measurements or ...
Hence, the efficiency of the antenna system becomes rather low if the antenna is surrounded by muscle tissue. As is apparent from the above expression, the power loss density Ploss is high in regions where the electric field is high. The electric field shows high values in the near zone ...
an auxiliary radiator control material near a radiator. CONSTITUTION:One side of materials for strip line which have copper foils 3 on both faces of a dielectric film 2 is etched to remove the copper foil except the part of a radiator 1, and the radiator 1 is formed, and an antenna feed...
An ultra-thin double-functional metasurface patch antenna (MPA) was proposed, where it can operate not only in the antenna mode but also can simultaneously act as perfect absorber for normal incident waves, suitable for RFID applications in the 868
NUMERICAL ANALYSIS OF STRIP ANTENNA BY A SURFACE PATCH TECHNIQUE - ScienceDirect The current distribution on a flat plate illuminated by a plane wave and the input admittance and current distribution of the strip dipole as the near field quantities have been investigated. The convergences of the ...
