Approximate formulas for the far field and gain of open-ended rectangular waveguide
IRE Transactions on Antennas and Propagation
Abstruct-Approximate formulas are derived for the far field and gain of standard, open-ended, rectangular waveguide probes operating within their recommended usable bandwidth. (Such probes are commonly used in making near-field antenna measurements.) The derivation assumes firstorder azimuthal dependence for the fields, and an E-plan pattern given by the traditional Stratton-Chu integration of the transverse electric QElo) mode. The H-plane pattern is estimated by two different methods. Thedoi:10.1109/tap.1984.1143332 fatcat:mun7dwfzkzhqbp6h4xftstxawq
