Abstract :
A moment-method model is presented for the radiation characteristics of the tapered slot antenna. It overcomes the shortcoming of an earlier theory. The method is rigorous for the air dielectric antennas. For dielectric-supported antennas, the method is approximate but accurate. The method is particularly accurate for antennas etched on substrates that are electrically thin or have a low dielectric constant, within the limits of (εr-1)d /λ0⩽0.1. Numerical results are presented for the radiation pattern and compared with experimental results to validate the model
