Circular Patch Antenna Calculator 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)) For more details on calculating microstrip line parameters, refer to the EM Talk Mi...

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...
