摘要：
A microstrip-fed truncated monopole antenna with radiation pattern and polarization reconfigurability is presented. The antenna fabricated on a substrate of dielectric constant 4.4 and thickness 1.6 mm is highly compact with an overall dimension of only 0.25 lambda(s) x 0.25 lambda(s). The pattern of the antenna is omnidirectional and is reconfigurable with the polarization in the orthogonal planes. The proposed antenna is suitable for 2.4-GHz wireless applications with a bandwidth of 95 MHz. The measured gain of the antenna is -1.1 dBi at the resonant frequency. The simulation (Ansoft HFSS) and measurement (R&S ZVB8 Vector Network Analyzer) results are also discussed.
