CST STUDIO: multimodal patch antenna

A rectangular patch (L = 76 mm, W = 50 mm, h = 1.524 mm, εr = 3.38) is powered by a coaxial probe. The central core of the connector is soldered to the patch at Dx = 29 mm, Dy = 15 mm from the bottom left corner.

Theoretically this position enables the four primary modes TM10 (1.075 GHz), TM01 (1.605 GHz), TM11 (1.955 GHz), and TM20 (2.145 GHz) to be excited with a correct matching.
