Capacitor Selection and Design for Magloop Antennas
The second downside to air variable capacitors is the ratio of max to minimum capacitance they can provide is somewhat restricted. To reach my goal of 20m to 80m I needed to achieve approximately 15 pF to 542 pF (more on that later).
A parallel plate capacitor consists of two parallel conducting plates separated by a dielectric, located at a small distance from each other. The electrical capacity C of parallel plate capacitor is equal to the product of the vacuum permittivity ε 0, permittivity of the dielectric e and the area S of the capacitor plate, divided by the distance d between the …
