Multi Bands Antenna for Wireless Communication System with Slots
Rapid growing of user in mobile communication and limited of spectrum created many frequency band used by operator. This letter propose a new antenna design with slots that covered multiple bands common used in mobile communication and Long Term Evolutions (LTEs) system. A single patch antenna operating at 2.6 GHz for LTE band was first designed and then optimization by introducing slots on antenna patch has been done to improve the antenna's Band Width (BW). As a transmitter antenna requires high gain for effective transmission, air gap and aluminum plate are used as ground element in order to achieve high gain performance.
