In this paper, a compact, wideband, printed antenna is proposed for millimeter-wave fifth-generation communication systems. The proposed design is a patch antenna with a defected ground structure, in which ground plane defects are utilized to reduce resonance and achieve wideband operation. The optimized antenna dimensions are 2.5 ㎜ × 4.5 ㎜ with a substrate thickness of 0.203 ㎜. A prototype antenna was fabricated and measured to verify the performance, and it was established that the simulated and measured results were in good agreement. The measured bandwidth was approximately 6.4 ㎓ (26.5–32.9 ㎓) with a peak gain of 5.62 ㏈i and an efficiency in operational bandwidth of 84%. The compactness, wide bandwidth, and decent gain suggest that the proposed antenna is a potential contender for forthcoming communication systems.

An electrically small ultra-wideband antenna for modern compact devices is presented in this paper. The antenna is constructed using a low-cost FR4 substrate, where etching slot and stub loading techniques are utilized to achieve miniaturization. The antenna comprises of simple geometrical structure with an overall size of 0.13 λ o × 0.19 λ o × 0.02 λ o ( λ o is the free-space wavelength at 3.5 GHz). A sample prototype was fabricated and tested to validate various performance parameters of the antenna. The antenna has measured 10 dB impedance bandwidth ranging from 3.55–12.16 GHz with a stable gain having a maximum value of 4.52 dBi. The performance comparison with state-of-the-art works shows that the proposed antenna off ers the advantages of miniaturized size, simple geometry along with competitive bandwidth and stable radiation characteristics.
