| Summary: | A triple band hybrid rectangular dielectric resonator antenna (RDRA) in place of multiple antennas to cover different bands of 4G long term evaluation (LTE) application is presented. An integrated approach using the combination of radiating slot and higher order mode techniques is employed to increase the number of resonances of a single RDRA. Multiple radiating modes are implemented to achieve three resonance bands 1.8, 2.6 and 3.4 GHz. The triple resonances are created simultaneously due to resonant modes of radiating rectangular ring slot feed coupled together with TE111x and TE131x modes of RDRA. A parametric study is carried out to investigate the triple resonances characteristics and to obtain optimal design parameters. The obtained optimized design is fabricated and validated experimentally. Impedance bandwidth (|S11| < − 6 dB) of 70% is achieved, fulfilling the broad coverage of LTE-time division duplex bands of (33–43). The measured return loss and radiation pattern are in good agreement with the simulated results. |
