Design of a Dual-Band, Quad-Element Dipole

A dual-resonance, quad-dipole antenna design is presented combining two dual-element dipoles, one of which is oriented in the YZ plane, and the other of which is in the XY plane. The antenna demonstrates a −10-dB IBW of 16.4% in the lower band, and 9.9% for the upper band. It demonstrates a peak realized gain in the lower band of 5.8 dBi in the
$+z$
direction, and the upper band of 5.4 dBi in the
$+x$
direction.
