GRANTE Corporation presents a novel slot antenna and a calculation technique on the 16th International Conference on the Computation of Electromagnetic Fields (Compumag 2007) in Aachen, Germany, June 24–28, 2007.

GRANTE Corporation and the Group of Electromegnetic Theory form the Department of Broadband Infocommunications and Electromagnetic Theory (Budapest University of Technology and Economics) introduce a novel slot antenna and describes a special calculation technique for the determination of the electromagnetic behaviour of the device.

In the paper we present a coupled calculation technique based on space segmentation for the calculation of radiation from tilted rectangular waveguide slot antennas. The basic idea of the method is the segmentation of the antenna into two space regions: an internal one, formed by the waveguide, and an external one, consisting of the half space where the slots are radiating into. The internal problem is solved using finite element method, while analytical calculations are performed in the external domain. Frequency-dependent behaviour of the analyzed antenna is also investigated. Measurements taken in the 2.4 and 5.8 GHz ISM frequency bands were found to be in a good agreement with the calculated results.
