Methods and apparatus for testing wireless devices. Devices being tested receive and transmit radio frequency test signals. These radio frequency test signals are received or transmitted using an antenna associated with the device, and then are transmitted or received using a unique wide-band tapered-slot antenna connected to a test system.

-j. Abstract. A Method of Moments (MoM) model for the analysis of the Linearly Tapered Slot Antenna (LTSA) is developed and implemented. The model employs an unequal size rectangular sectioning for conducting parts of the antenna. Piecewise sinusoidal basis functions are used for the expansion of conductor current. Moment Method Analysis of Parallel Plate Slot Antennas "Moment Method Analysis of Parallel Plate Slot Antennas" Manuel Sierra Castañer , Jiro Hirokawa , Makoto Ando Abstract: The authors propose a Moment Method Analysis for the Analysis of a Parallel Plate Slot Array, excited by a feed waveguide, based on the Flocket 's Theorem. Method of Moments Applied to Antennas Method of Moments Applied to Antennas 9 In the MoM, this measure is obtained in the following way. Both sides of equation (37) are multiplied by a known, properly selected function, referred to as the weighting function, wm, and the results integrated over a spatial region.

A slot antenna, as shown in Figure 6.16, is considered another basic radiating element. It is realized by removing a small area of metal from an infinite ground plane. For a practical design, however, the ground plane may be finite but large in size. Susceptance is difficult to calculate, with both moment methods ... An Introduction of Aperture Coupled Microstrip Slot Antenna An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The slot shape also affects the radiation patterns by choosing the proper shape of the slot.
