摘要
An antenna is an essential element of wireless communication systems, used to transmit and receive electromagnetic waves. Out of several types of antennas, reconfigurable antennas are particularly interesting. They can change their operating parameters based on changing needs. A reconfigurable antenna has the capability to change its operating parameters dynamically applying external control signals. This flexibility minimizes the use of multiple antennas in one system, thereby conserving space, cost, and complexity. A frequency-reconfigurable bow-tie shaped microstrip patch antenna is proposed in this research. It aims to provide wide frequency coverage while keeping compact dimensions and efficient operation. The antenna is made on an FR4 epoxy substrate, which is chosen for its low cost and good electrical properties. The structure is simulated using HFSS software to study and improve its electromagnetic performance. The antenna uses a coplanar waveguide (CPW) feed and includes two PIN diodes along with a shorting pin for frequency switching. Varactor diodes are also added for continuous tuning of the resonant frequency. The antenna can operate at different frequencies—4.55 GHz, 7.45 GHz, 4.51 GHz, and 6.88 GHz—demonstrating its reconfigurability with respect to frequency. Additionally, using varactor diodes expands the antenna's tuning range from 3.04 GHz to 5.89 GHz.
