New antenna model could speed up wireless device design
Researchers have developed a faster way to simulate how antennas respond to electromagnetic pulses, potentially cutting design time for wireless communications systems. The circuit-based approach offers manufacturers a practical alternative to expensive computer simulations, making it easier to test antenna performance before building prototypes.
Originaltitel: Transient Plane-Wave Response of a Dual-Loaded Small-Loop Antenna: A Time-Domain Approach Using Quasi-Static Thin-Wire Partial Elements
<p>An accurate circuit model of a two-port square-loop antenna is presented in this article. The circuit consists of equivalent lumped elements based on the quasi-static partial element equivalent circuit (PEEC) method, under the thin-wire approximation. The introduced model is applied to calculate the transient port response for an impulsive electromagnetic (EM) plane-wave excitation, enabling separate electric and magnetic effects analysis. The presented results are validated with the aid of both state-of-the-art analytical solutions and PEEC method, and with a commercial EM tool.</p>
