Quasi-Isotropic Hybrid Dielectric Resonator Antenna—Bow-Tie Patch with Harmonic Suppression

This paper proposes a quasi-isotropic hybrid dielectric resonator antenna (DRA) and bow-tie patch with harmonics suppression. The suggested consists of DRA, patch, microstrip seventh-order Chebyshev low-pass filter. By loading on the designed pattern is realized. filter was applied to feed line, were reduced in section separate operating band remove generated by proposed antenna. simulated S11 that satisfies below −10 dB 3.09–3.3 GHz (6.25%), measured 3.10–3.28 (5.64%). gain difference considering all radiating regions (0∘≤φ≤360∘ 0∘≤θ≤180∘) 7.211 dB. Compared without filter, harmonic 10.847 15.774 isolation second third are 10.10 18.94 dB, respectively. considered be applicable applications require radio wave reception directions such as wireless point access points, internet things frequency identification, expected contribute reducing size RF system.
