Wideband low-profile null-filled monopole antenna for aircraft flush-mount applications

A wideband low-profile null-filled monopole antenna for aircraft flush-mount applications is presented. The antenna consists of a semicircular monopole and a direct-fed dual loop in a flanged cylindrical cavity. The zenith null in the monopole radiation pattern is filled by horizontal currents of th...

Zusammenfassung:	A wideband low-profile null-filled monopole antenna for aircraft flush-mount applications is presented. The antenna consists of a semicircular monopole and a direct-fed dual loop in a flanged cylindrical cavity. The zenith null in the monopole radiation pattern is filled by horizontal currents of the dual loop. Measurement shows that the proposed antenna has a reflection coefficient of
