Abstract
An all-fiber antenna with a piezoelectric polymer-coated circular-core D fiber has been characterized by finite-element analysis. The response of the D-fiber antenna was determined over a wide frequency range from 1 to 500 MHz. The modeling predicts an electric-field-induced phase shift of 2.43 x 10(-5) rad/(V/m)/m at 5 MHz. At frequencies higher than 8 MHz the optical response is dominated by radial resonances of the D-fiber-coating composite. From the simulation results a minimum detectable electric field of 41-muV/m has been achieved with a 1-km length of coated D fiber. In addition, a D-fiber antenna network intended for microcellular communications has been analyzed by shot-noise-limited detection.

Main findings
Finite-element modeling of a piezoelectric polymer-coated circular-core D-fiber antenna predicted an electric-field-induced phase shift of 2.43 × 10^-5 rad/(V/m)/m at 5 MHz. The response was modeled from 1 to 500 MHz, with optical response dominated by radial resonances above 8 MHz. Simulations indicated a minimum detectable electric field of 41 µV/m using a 1-km length of coated D fiber, and a D-fiber antenna network for microcellular communications was analyzed under shot-noise-limited detection.
Outcomes measured
- Optical phase shift response to electric field (rad/(V/m)/m)
- Frequency-dependent optical response/resonances (1–500 MHz)
- Minimum detectable electric field (µV/m)
- Shot-noise-limited detection performance for D-fiber antenna network
Limitations
- Finite-element simulation/modeling study; no experimental validation described in abstract
- Key parameters (e.g., field strengths used in simulations, coating properties, boundary conditions) not detailed in abstract
