Abstract: In this letter, a frequency and linear-polarization (LP) reconfigurable antenna is proposed. The antenna consists of two pairs of printed dipoles as the primary radiating patches. By independently controlling the direction of the flowing current using loaded PIN diodes, the dynamic reconfiguration of both frequency and linear polarization can be realized. In addition, a dual-band artificial magnetic conductor (AMC) reflector is added under the radiator, which can effectively reduce the antenna profile to 0.1λ0 (12.4mm, where λ0 is the wavelength at low operating frequency). Both simulated and experimental results show that the proposed antenna can operate in four modes: 0° LP low-frequency (2.36-2.77GHz) state, 0° LP high-frequency (3.25-3.68GHz) state, 90° LP low-frequency state, and 90° LP high-frequency state. The antenna exhibits stable radiation patterns, with gain values of 7.56 dBi in the low-frequency state and 8.03 dBi in the high-frequency state. This antenna is suitable for ISM band applications, such as Wi-Fi (2.4-2.48GHz) and Bluetooth (2.4-2.48GHz), as well as TDD Band 42, meeting the requirements of modern wireless communication systems.
