Abstract:
This paper introduces a wideband star-shaped
planar antenna with a liquid crystal (LC) material at Ka-band.
The antenna array consists of the LC cavity and planar antenna
elements with a microstrip feedline. Planar antenna array is
designed with eight star-shaped patches. To check the LC
dielectric constant at Ka-band, the designed antenna is fabricated
and measured result of reflection coefficient(S11) ≤ -10 dB shows
across the wideband (27 GHz – 40 GHz) without DC biasing with
bean scanning from -62° to +5° and gain ≥ 8.15 dBi. The frequency
range can be tuned with applied biasing voltage on the LC cavity.
