AN ACCURATE EDGE EXTENSION FORMULA FOR CALCULATING RESONANT FREQUENCY OF ELECTRICALLY THIN AND THICK RECTANGULAR PATCH ANTENNAS WITH AND WITHOUT AIR GAPS

A new and accurate edge extension formula based on the Taguchi method is proposed to calculate the resonant frequency of electrically thin and thick rectangular patch antennas with an air gap (RPAAG) and rectangular patch antennas without an air gap.Based on 3205 antennas data random distribution in the electrical Collections substrate thickness h/

Since the introduction of in vitro fertilization (IVF) in 1978, over five million babies have been born worldwide using IVF.Contrary to the perception of many, IVF does not guarantee measuring cup success.Almost 50% of couples that start IVF will remain childless, even if they undergo multiple IVF cycles.The decision to start or pursue with IVF is

Two unique bluff body flow control methods using a small rod have been proposed in previous studies.The first is the forced reattachment method, which is a type of separated Ballpoint pen shear layer control.This method reduces drag and generates a lift.The second is the front rod method, which involves the placement of a small rod upstream of the
