Abstract
An antenna of the present disclosure has a housing having a shallow cavity in a top of the housing and a shallow cavity in a bottom of the housing. The antenna further has a substantially circular radiating element disposed in the shallow cavity on the top of the housing, the radiating element having an arc shape slot. In addition, the antenna has a substantially circular parasitic element disposed in the shallow cavity on the bottom of the housing.
Claims10
An antenna, comprising:
- a housing having a top shallow cavity in a top of the housing and a bottom shallow cavity in a bottom of the housing;
- a substantially circular radiating element disposed in the top shallow cavity on the top of the housing, the radiating element having an arc-shaped slot and a central opening, the central opening disposed inwardly from the arc-shaped slot;
- a substantially circular parasitic element disposed in the bottom shallow cavity on the bottom of the housing;
- a tube affixed to the bottom of the housing;
- a substantially circular protrusion extending from the top of the housing, the protrusion extending through the central opening of the radiating element, the protrusion having an opening.

An antenna, comprising:
- a housing having a top shallow cavity in a top of the housing and a bottom shallow cavity in a bottom of the housing;
- a substantially circular radiating element disposed in the top shallow cavity on the top of the housing, the radiating element having an arc-shaped slot and a central opening, the central opening disposed inwardly from the arc-shaped slot;
- a substantially circular parasitic element disposed in the bottom shallow cavity on the bottom of the housing;
- a tube affixed to the bottom of the housing, the tube off center of the bottom of the housing;
- and wherein a balun having a first and second trace runs through the tube.

An antenna, comprising:
- a housing having a top shallow cavity in a top of the housing;
- a substantially circular radiating element disposed within the cavity, the radiating element having an arc-shaped slot formed therein;
- a substantially circular parasitic element separated from the substantially circular radiating element by an insulating material, the parasitic element disposed within a bottom shallow cavity in a bottom of the housing;
- and
- a cable electrically connected to the radiating element;
- wherein the cable is a coaxial cable and is connected to the radiating element across the slot such that a shield of the coaxial cable is electrically connected to a first side of the slot and a wire of the coaxial cable is electrically connected to a second side of the slot, wherein the cable is a balun formed by electrically connecting a shield of a coaxial cable to a first trace and a wire of the coaxial cable to a second trace.
