Abstract

Apparatus for connecting the female connector end of a coaxial antenna lead to the members of a slot antenna includes a first connecting member having a flat base connected to one antenna member with a pair of arms at the base end farthest from the slot adapted to engage the female end of the coaxial lead and connect the outer conductor to the one antenna member. A forked extension projects from the base end nearest the slot, and the base flares outwardly in width from the arms to the forked extension to dissipate the radial electromagnetic field of the coaxial lead so it does not interfere with the slot. A second conducting member includes a conductor adapted at one end to engage the inner conductor at the female connector end of the coaxial lead and at the other end to engage the other antenna member. An insulator engages the forked extension to interlock the first and second connecting members.

Claims

1. A pair of physically interlocking connecting members adapted to electrically connect the inner and outer conductors of a coaxial antenna lead through connection to the female connector end thereof to the two members of a slot antenna while preventing interference by the radial electromagnetic field of the coaxial antenna lead with the electromagnetic field of the slot, the pair comprising, in combination:

a first electrically conducting connecting member comprising a flat base adapted for physical and electrical connection to one of said antenna members, a pair of arms projecting outwardly from the end of the base farthest from the slot and being adapted to physically engage the female connector end of the coaxial antenna lead and electrically connect with the outer conductor thereof, and a forked extension projecting outwardly from the end of the base nearest the slot, the base flaring outwardly in width from the end farthest to the end nearest the slot to dissipate the radial electromagnetic field of the coaxial antenna lead; and

a second connecting member comprising a conductor adapted at one end to physically engage the female connector end of the coaxial antenna lead and electrically connect with the inner conductor thereof and at the other end to electrically connect with the second antenna member, and further comprising insulating means adapted to engage the forked extension of the first connecting member to interlock therewith.

2. Apparatus for connecting the female connector end of a coaxial antenna lead to a slot antenna comprising two antenna members defining a slot therebetween, the coaxial antenna lead including inner and outer conductors and an outer annular end member electrically connected to the outer conductor and having a radial projection therefrom, said apparatus comprising, in combination:

a first connecting member comprising an electrically conductive material, said connecting member further comprising a pair of arms adapted to engage the outer annular end member therebetween, at least one of said arms having an opening adapted to engage the radial projection, the connecting member further comprising a flat base supporting said arms and adapted to be physically and electrically connected to the first antenna member, whereby the outer conductor is electrically connected to said first antenna member, the base extending from said arms to a slot end adjacent said slot and flaring outwardly from a narrow width by said arms to a wider width at said slot end, whereby the radial electromagnetic field of the coaxial antenna lead is dissipated and does not interfere with the slot electromagnetic field, the first connecting member further comprising a forked extension extending substantially perpendicularly from the slot end of said base; and

a second connecting member comprising a conducting member adapted to cross said slot and engage at one end the inner conductor of the coaxial antenna lead and at the other end the second antenna member, the second connecting member further comprising insulating means adapted to engage the forked extension of the first connecting member and thereby prevent accidental withdrawal of the conducting means from engagement with the inner conductor of the coaxial antenna lead.
