At present, the proposed microwave power detection systems cannot provide a high dynamic detection range and measurement sensitivity at the same time. Additionally, the frequency band of these detection systems cannot cover the 5G-communication frequency band. In this work, a novel microwave power detection system is proposed to measure the power of the 5G-communication frequency band. The detection system is composed of a signal receiving module, a power detection module and a data processing module. Experiments show that the detection frequency band of this system ranges from 1.4 GHz to 5.3 GHz, the dynamic measurement range is 70 dB, the minimum detection power is −68 dBm, and the sensitivity is 22.3 mV/dBm. Compared with other detection systems, the performance of this detection system in the 5G-communication frequency band is significantly improved. Therefore, this microwave power detection system has certain reference significance and application value in the microwave signal detection of 5G communication systems.

In the present article authors propose the design and analysis of an octagonal shape multiband metamaterial loaded antenna with implementation of hybrid fractal geometry for wireless applications. Multiband features in the antenna structure is realized by applying the slotted and hybrid fractalization of Moore and Koch curve approach in radiating section along with introduction of two metamaterial SRR cells. The frequency band reconfigurability characteristics in proposed design is achieved by placing the PIN diode inside the connecting strip between the central hybrid fractal geometry and feedline. During forward bias condition of PIN diode antenna structure resonates at hepta (seven) band mode at WiMAX (3.5 GHz)/Lower C-band (4.41 GHz)/WLAN (5.4/5.8 GHz)/Lower X-band (8.26 GHz)/Upper X-band (10.48 GHz)/Lower Ku-band (13.35 GHz)/Middle Ku-band (14.42 GHz) wireless standards with S11 ≤ −10 dB. Proposed antenna represent the hexa and hepta band features during reverse bias (OFF-state) and forward bias condition (ON-state) of PIN diode respectively. A stable and consistent radiation patterns, appropriate impedance matching and an acceptable gain are achieved at all the operating frequencies of the proposed antenna.

In this article, the authors present a hepta band metamaterial inspired hybrid fractal octagonal shape antenna for wireless applications. Multiband characteristics in the proposed design are achieved by hybrid fractal form of Moore curve and Koch curve with metamaterial loading. A well matched impedance bandwidth (S 11 ≤ −10 dB) is accomplished at seven microwave frequency bands, Upper L band (1.93 ∼ 2.08 GHz), S band, WiMAX (3.3 ∼ 3.7 GHz), C band, WLAN (5.4 ∼ 5.9 GHz), C band, IEEE INSAT application (6.5 ∼ 7.2 GHz), X band terrestrial broadband, space communication and Radio Navigation (RN) application (8.51 ∼ 11.05 GHz), Lower Ku band direct broadcast satellite service (12.2 ∼ 12.7 GHz), and Middle Ku band satellite communication operating band (14.73 ∼ 15.84 GHz) covering various wireless applications. The antenna achieves hexa/penta band characteristics during switching ON/OFF state of PIN diode placed between the Moore curve structure (attached with centered SRR cell) and feedline. Radiation patterns are found in stable forms at all the resonant frequencies. Measured results of the proposed design are compared with simulated ones indicating good agreement between them.
