Circular Patch Antenna Calculator

Theory about Circular Patch Antennas:

  • Structure: A circular patch antenna consists of a thin metallic disk (patch) mounted on a dielectric substrate.
  • Operating Principle: It radiates electromagnetic waves when fed with RF energy.
  • Key Parameters:
    • Frequency (f): The operating frequency, typically in GHz.
    • Dielectric Constant (εr): Indicates how well the substrate material can store electrical energy.
    • Substrate Thickness (h): Affects bandwidth and efficiency.
  • Patch Radius (a): Can be calculated using the formula:
    a ≈ F / √(1 + (2 * h * logTerm) / (π * εr * F))

Circular Loop Antenna Calculator Circular Loop Antenna Calculator Loop Antenna: A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor, usually fed by a balanced source or feeding a balanced load. Loop antennas are often used in direction finding and have applications in radio broadcasting and wireless communication systems. Types of Loop Antennas: Small Loop Antenna: Used for reception and is electrically small compared to the wavelength. Large Loop Antenna: Its circumference is comparable to the wavelength of the signal it transmits or receives. Formula for Circular Loop Antenna: The radius of a circular loop antenna is calculated using the formula: r = c / (2πf) Where: r = radius...
