A High-Performance Antenna With Simultaneous Frequency and Polarization Reconfigurability
This letter presents a reconfigurable antenna designed for base station applications. The antenna employs PIN diodes controlled by a spider-shaped dc bias circuit to achieve both frequency and polarization reconfigurability. It has four contiguous tunable frequency bands, operating within the frequency range of 2.20 GHz to 3.50 GHz. These bands cover the mobile communication frequency bands

78. Each frequency band offers 16 polarization directions, providing a versatile range of options for polarization configurations. The antenna exhibits gains higher than 8 dBi, radiation efficiencies greater than 70%, front-to-back ratios exceeding 19 dB, and half-power beamwidths ranging from 53° to 62°. This antenna not only covers the majority of mobile communication frequency bands but also offers the advantages of cost savings and channel contamination reduction.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
