摘要：
This letter exploits a dual feature of rectangular open-ended ground slot to design an integrated 4G/5G antenna for mobile devices. In the proposed configuration, the antenna footprint of the 4G module is used for the installation of a 5G antenna module. While the entire rectangular slot is structured to operate at 800 MHz and 2 GHz, an array of 4-element Vivaldi antenna operating at 28 GHz is added within the slot space. This array provides end-fire radiation with 11 dBi peak realized gain. To validate the design concept, a prototype is fabricated on a RO-5880 substrate with an overall size of. The results show that the design covers two low frequency bands (from 770 to 810 MHz and from 1.9 to 2.6 GHz) with less than dB reflection coefficient and a wideband millimeter-wave frequency range (from 26 to 32 GHz) with less than dB reflection coefficient. A multiple-input-multiple-output (MIMO) configuration of the antenna is also realized with diversity performances verified.
