Abstract
A wideband phased array antenna is provided. The wideband phased array antenna includes a plurality of antenna cells. Each of the antenna cells is configured to communicate over a frequency band ranging from 24 GHz to 52 GHz. Furthermore, one or more of the antenna cells includes a driven element and a parasitic element. The driven element is disposed on a first substrate that includes a first dielectric material. The parasitic element is disposed on a second substrate positioned relative to the first substrate such that a gap is defined between the first substrate and the second substrate. The second substrate includes a second dielectric material that is different than the first dielectric material.
Claims19
A wideband phased array antenna comprising:
- a plurality of antenna cells, each of the antenna cells configured to communicate over a frequency band ranging from 24 GHz to 52 GHz, one or more of the antenna cells comprising:
- a driven element disposed on a first substrate, the first substrate comprising a first dielectric material;
- and
- a parasitic element disposed on a second substrate positioned relative to the first substrate such that a gap is defined between the first substrate and the second substrate, the second substrate comprising a second dielectric material, the second dielectric material being different than the first dielectric material,
- wherein a cross-sectional area of the driven element is smaller than a cross-sectional area of the parasitic element.
An antenna system comprising:
- a phase shifter circuit electrically coupled to a radio frequency (RF) source;
- and
- a wideband phased array antenna electrically coupled to the phase shifter circuit, the wideband phased array antenna comprising a plurality of antenna cells, each of the antenna cells configured to communicate over a frequency band ranging from 24 GHz to 52 GHz, one or more of the antenna cells comprising:
- a driven element disposed on a first substrate, the first substrate comprising a first dielectric material;
- and
- a parasitic element disposed on a second substrate positioned relative to the first substrate such that a gap is defined between the first substrate and the second substrate, the second substrate comprising a second dielectric material, the second dielectric material being different than the first dielectric material,
- wherein a cross-sectional area of the driven element is smaller than a cross-sectional area of the parasitic element.
