Low Profile Microstrip Resonator Dielectric Sensor for Development of Artificial Phantom

Metamaterial‐inspired miniaturized and broadband U‐slotted patch antenna for the 5G communications covering the full N78 band

“…This work shows a low-cost MUPA using the conceptual combination method (as the mushroom metamaterials 20 and U-slotted patch 25 ) for the N78 band mobile communication. In addition to this design, it is promising as well by synergistically utilizing some other metamaterials [13][14][15][16][17][18][19][20] and broadband techniques, [21][22][23][24][25][26][27][28][29][30][31] still to realize a compact and broadband MSA. A similar example was numerically reported in our previous work, 32 by jointly designing the C-slotted (arc shaped slotted) circular patch 27 and sector mushroom metamaterials.…”

“…Another common miniaturization technique is to cut meander slots 10–12 on the antenna patch (or ground) since the meandered structures can physically increase the current path. In recent decade, an alternative method was proposed by loading new artificial metamaterials 13–20 . These metamaterials are made of low‐cost low‐dielectric‐constant (low‐dk) dielectrics but exhibit effective high‐index, which can successfully shrink the MSAs as well 13–20 .…”

Material characterization by using T- stub based microstrip patch sensor

“…But some of these methods have certain limitations like in coaxial probe method repeated calibration is required to get error free results, in transmission line method sample preparation is difficult which leads do less accurate results, in free space method errors occurs due to diffraction. In recent times, microstrip patch sensor which is type of resonant methods used for material characterization because of its planar geometry, low cost, conformability and easy fabrication [1]. Microstrip patch sensor contains top layer, middle layer and bottom layer.…”

“…Using patch antenna sensor, refection and transmission response of the sensor is analysed depending upon number of ports used in design, like in single port, sensing is done by analysing reflection of EM waves and for dual port, reflection as well as transmission response can be analysed as observed in ref. [1,6,9]. This article presents, a single T-stub based structure for analysing the properties of material.…”
