Tuneable dual-band antenna for sub 1 GHz cellular mobile radio applications

摘要

In this paper, a compact tuneable dual-band slotudantenna operating over the frequency range from 560 MHz to 1udGHz is presented and evaluated through a hardware-in-the-loopudtest-bed. The co-existence of high order modulation schemes isudinvestigated in DTT and low LTE bands. EVM results show thatudthe proposed antenna can support two operating frequencyudbands simultaneously where each band can be tunedudindependently for carrier aggregation with negligible crosstalk.
