Summary
This study introduces a novel wideband patch antenna for 5G sub-6 GHz networks, achieving stable gain and high efficiency in a compact design. The antenna utilizes parasitic stubs, L-slots, a meandered feed line, and a defected ground structure for enhanced performance.
Area of Science:
- Electromagnetics and Antenna Design
- Wireless Communication Technologies
Background:
- 5G sub-6 GHz networks require compact, wideband, and efficient antennas with stable gain.
- Existing designs often struggle to balance these requirements within limited dimensions.
Purpose of the Study:
- To present a gain-stabilized wideband patch antenna for 5G applications.
- To systematically integrate multiple design elements for optimized performance.
Main Methods:
- A six-stage design approach was employed, integrating circular parasitic stubs, L-slots, a meandered feed line, and a defected ground structure.
- These elements were interactively optimized for multi-frequency impedance matching and resonance mode control.
Main Results:
- The optimized antenna exhibits dual resonances at 3.6 and 6.1 GHz, covering a wide operational band of 3.2-6.6 GHz.
- It achieves a consistent realized gain of 2.6-2.7 dBi (±0.8 dB), radiation efficiency above 90%, and low group delay variation (<0.5 ns).
Conclusions:
- The systematic integration of complementary techniques enables simultaneous wideband operation, exceptional gain stability, and low group delay.
- The proposed antenna design is highly suitable for compact 5G wireless devices.

1.1K
Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.

01:15Standing Electromagnetic Waves
2.5K
Electromagnetic waves can be reflected; the surface of a conductor or a dielectric can act as a reflector. As electric and magnetic fields obey the superposition principle, so do electromagnetic waves. The superposition of an incident wave and a reflected electromagnetic wave produces a standing wave analogous to the standing waves created on a stretched string.

01:24IR Frequency Region: X–H Stretching
1.8K
In IR spectroscopy, signals produced by the X−H bonds (such as C−H, O−H, or N−H) can be observed in the frequency range of 2700–4000 cm–1. The C−H stretching vibration forms sharp bands in the region 2850–3000 cm–1. The presence of the O−H stretching vibration leads to the forming of an absorption band in the frequency range 3650–3200 cm−1. At the same time, N−H stretching can be confirmed by absorption bands in...

01:17Bandpass Sampling
627
In signal processing, bandpass sampling is an effective technique for sampling signals that have most of their energy concentrated within a narrow frequency band. This type of signal is known as a bandpass signal. The key principle of bandpass sampling involves sampling the signal at a rate that is greater than twice the signal's bandwidth to prevent aliasing.
A bandpass signal has a spectrum with a lower frequency limit, denoted as ω1, and an upper frequency limit, denoted as ω2....

01:24Characteristics of Series Resonant Circuit
806
Series resonance occurs in a circuit containing inductive (L), capacitive (C), and resistive (R) elements connected sequentially. At the resonance frequency, the inductive and capacitive reactances are equal in magnitude but opposite in sign, effectively canceling each other. This causes the circuit's impedance is minimal, primarily determined by the resistance R. The resonant frequency of an RLC circuit is defined as:
