“…For miniaturizing the MPA's dimensions and enhancing its performance, a thin-film material with very high dielectric permittivity (ε r2 = 250) and low loss (tan δ = 0.02), i.e., ferroelectric material (B 0.8 S 0.2 TiO 3 ) [40,41] is loaded into the patch. The flowchart in Figure 1 shows the processing steps to integrate the thin-film material in the antenna.…”

“…For this reason, a thin-film material with high dielectric permittivity has been used. In this study, a ferroelectric material that has a relative permittivity ε r2 = 250 has been used [38,41]. However, the use of a high relative permittivity substrate results in a narrow bandwidth.…”

“…The first substrate (lower substrate) is FR-4 with thickness D 1 equal to 1.58 mm and permittivity ε r1 equal to 4.4. The second substrate (upper substrate) consists of a thin film of a ferroelectric material B 0.8 S 0.2 TiO 3 (BST) of thickness D 2 and is characterized by a very high dielectric permittivity (ε r2 = 250)[39,41].…”

The main objective of this work is to propose an approach for improving the performance of miniaturized microstrip patch antennas (MPAs) that are loaded with a thin film consisting of a high relative permittivity material. The method uses a thin film to decrease the antenna’s resonance frequency while keeping the antenna’s patch dimensions. For the enhancement of the antenna’s performance with a thin film, the dimensions of the patch of the designed antenna are optimized utilizing genetic algorithms (GAs). The resonance frequency of the microstrip patch antenna was changed from 5.8 GHz to 4.0 GHz, and the area of the proposed antenna was minimized by around 60%, especially in comparison to a conventional antenna alone without thin film. Most of the performances of the proposed antenna such as the return loss, bandwidth, and voltage standing wave ratio (VSWR) were improved.

“…This is well suited to the system requiring static changes but there is lot of issues faced due to the hybridism so the authors in [31] reported the design with elimination of glass and clubbed two container. Recently in [32] investigated the hybrid effect of oil and water, interestingly to make the antenna tunable they used the principle of communicating vessels, however more investigation is required on this topic to improve their utilization in real world application.…”

The major aim of this paper is to collate the information on application oriented performance of DRA. Here we dominantly discussed on multi functional performance of antenna as a package material along as oscillator and filter and multi aspects of transparent DRA. A glimpse on On-Chip-DRA considering difficulty of the process to encourage the knowledge to overcome discrepancy. A note on Material and geometry influence in different application including RADAR, RFID is discussed. The advantage of small ground plane is discussed and markedly we produced details on Biomedical application of DRA that contrived a significant distinct compared with other Review articles of DRA.
