In this paper, a novel dual-band, dual-polarized, miniaturized and low-profile base station antenna operating in the frequency bands of 820–960 and 1710–2170 MHz is designed. Elements are arranged such that high-frequency elements are embedded in low frequency elements to reduce volume. A baffle is used to reflect the transmitted power density in the forward direction and also improve isolation between...
A radio frequency identification (RFID) tag antenna mountable on metal surfaces is designed. It operates in the UHF frequency band (usually called UHF RFID tag) and is matched to the Alien Higgs-3 chip (a kind of RF IC chip). Based on the special structure of the microstrip antenna—two conducting surfaces: the antenna plane and the ground plane, we embed a pair of E-type slot to obtain broadband characteristics...
