Abstract: A panel-mountable header connector includes conductors and a housing. The housing holds the conductors in a cavity of the housing. The housing has a front end and a rear end. The housing has a latch set and a stop feature which define a panel mounting zone therebetween. The panel mounting zone is configured to align with an opening in a panel when the housing is mounted to the panel. The latch set is configured to engage a front side of the panel, and the stop feature is configured to engage a rear side of the panel to retain the panel in the panel mounting zone. At least one of the latch set or the stop feature is stepped such that a width of the panel mounting zone is variable to accommodate the panel having one of multiple thicknesses.

Abstract: A dielectrically-loaded antenna for operation at frequencies in excess of 200 MHz includes an antenna element structure disposed on a high dielectric constant core, which element structure comprises a pair of laterally opposed groups, of helical antenna elements. Each group comprises first and second mutually adjacent elements, of different thicknesses providing looped conductive paths on the antenna, formed by the first elements of each group and the second elements of each group respectively, which resonate at differing respective resonant frequencies to yield a relatively wide operating bandwidth. The helical elements of each group define, between them, part of an elongate channel which has an overall electrical length in the region of n&lgr;/2 within the operating frequency band to provide isolation between the looped conductive paths. The major part of each such channel is located between the elements so as to minimise intrusion with other parts of the antenna.
