Area of Science:

Electrical Engineering
Materials Science

Background:

Traditional antennas often lack frequency tunability and compactness.
Liquid crystal (LC) materials offer unique dielectric properties for tunable RF devices.

Purpose of the Study:

To develop a compact, frequency reconfigurable antenna with enhanced bandwidth using a multilayer liquid crystal structure.
To investigate the performance of an inverted microstrip line antenna integrated with an LC-injected cavity.

Main Methods:

A three-layer stacked structure incorporating liquid crystal material was designed.
An inverted microstrip line served as both a radiating element and bias electrode, in contact with the LC.
A parasitic patch was added for bandwidth enhancement, and a bias tee was integrated for signal integrity.

Main Results:

The proposed antenna demonstrated excellent impedance matching and stable radiation patterns across its operational frequency range.
Bandwidth was tripled at a center frequency of 30.3 GHz compared to existing LC antennas.
The effective area was reduced by 75.4% (154 mm² vs 625 mm²).

Conclusions:

The multilayer LC antenna offers significant improvements in bandwidth and size reduction.
The design is suitable for applications requiring compact and tunable RF components.
