“…To increase impedance matching, the ground plane width has been reduced and adjusted by loading four slots with the appropriate dimensions at the appropriate locations. Also in Maity et al, 14 another hybrid shape super broadband (2–95 GHz) microstrip patch antenna was proposed with measurement result up to 40 GHz. The suggested antenna's radiating patch has been designed by overlapping reference rectangle shaped patch with two ellipses and also two notches.…”

SummaryIncorporating the better impedance matching capability of planar curved radiating patch, a miniaturized broadband planar antenna has been designed, analyzed, and integrated with frequency selective surface (FSS) to accomplish higher gain for various short‐range and long‐range modern wireless communication applications. Physical and electrical volume of the presented antenna is 25 × 20 × 1.6 and 0.25 × 0.20 × 0.016, respectively. The proposed radiating patch is constructed from a conventional rectangular patch by transforming the upper side of the patch into a semi‐circular shape and the lower side of the patch into a staircase‐like shape. Measured outcomes of the designed antenna show a very large operating bandwidth of 19.8 GHz (3–22.8 GHz) with a fractional bandwidth (FBW) of 153.5% and bandwidth dimension ratio (BDR) of 3070. An equivalent circuit model (ECM) of the proposed antenna is developed using an advanced design system (ADS) circuit simulator. The frequency responses of the ECM are compared with the simulation done by CST Microwave Studio Suite software and measurement results, which show good agreement. An FSS structure with stop band from 2–28 GHz is positioned beneath the proposed antenna at optimal position (27 mm below the antenna) to enhance the gain up to 8.9 dBi. The presented antenna and FSS are fabricated on FR4 substrate and experimentally verified using standard microwave measurement setup.

“…The reflection coefficient is good, but the impedance bandwidth is narrow, only 73.8MHz. Single-layer structures are easier to design, but multilayer structures offer higher gains [11]. Using a single Frequency Selective Surface (FSS) substrate to improve efficiency can significantly reduce the return loss and effectively reduce the antenna size by 80.3%.…”

This study proposes a Taiji-shaped microstrip patch antenna without affecting its size and design complexity. The radiation patch adopts a Taiji-like shape design, and the traditional Chinese Bagua-shaped parasitic element is loaded on the periphery of the radiation patch on the surface of the dielectric substrate to optimize the impedance matching further and improve the gain. The software HFSS15.0 is used to simulate the antenna and compare the results. The results show that the antenna achieves dual-band characteristics at 2.45GHz and 5.04GHz, has an impedance bandwidth of 110MHz and 250MHz, and has a positive gain of 7.13dB. The proposed antenna is suitable for the field of wireless communication.

Herein, the microwave transmission method is proposed that demonstrates such advantages as non-invasiveness, excellent penetration performance, and fast detection. As a key component of the microwave method water content measurement instrument, the antenna is required to have a smaller radiation size than the inner diameter of the oil pipe. To address this technical challenge, a small-sized microwave projection method based on water content measurement antenna is designed in this study for the water content measurement of oil-water mixtures in downhole pipelines. Also, the half-cut antenna with a size of [Formula: see text] is proposed to operate in the frequency band of 2–6 GHz (The measured gain of the antenna varies from 2.48 dBi to 4.98 dBi). Then, the designed half-cut antenna is applied to the established water-content test environment for analysis as to the relationship between water content and the variation in transmission coefficient of the half-cut antenna. According to the test results, the relative water content error is about 0.31% between the simulation and measured results for the transmission coefficient [Formula: see text] in the range of 0%–30%, while that is about 0.16% for the transmission coefficient [Formula: see text] in the range of 40%–100%. The experimental results can be extended to the measurement of the part with high water content of the oil-water mixture in the pipeline, which provides a practical reference for field tests and basic research.
