Batwing and corner antennas

Sheet-metal batwing antennas and circularly polarised corner antennas

Sheet-metal batwing, 200–400 MHz
Sheet-metal batwing, 200–400 MHz

Overview

Wideband sheet-metal antennas for EMC testing and scanning receivers. The model and its optimisation are ready; validation is in progress, so values are given on request.

From the simplest to the most complex: a 200–400 MHz sheet-metal batwing over a ground plane, a corrugated batwing, a meander version for a smaller size, a crossed pair for circular polarisation, the batwing as an array element; and a circularly polarised corner antenna: a dipole in a 45° or 90° dihedral, with size optimisation and tolerances.

Typical performance

Typical values describe the antenna class, not a guarantee for a unit; “computed” marks our own simulated example.
