Design of Microstrip Patch Antenna on Rubber Substrate with DGS for WBAN Applications

Design a compact CPW monopole antenna on rubber substrate for ISM band application

“…The patch width and length calculated by ( 1) and (2). Furthermore, the ground width (Wg) and ground length (Lg) calculated by using (3) and ( 4) resultant value inserted in Table 1.…”

“…In addition, the thickness of the dielectric layer and the copper were 1.88mm and 0.035mm, respectively. In the existing work [2], a microstrip antenna with three layers was developed to consist of a copper sheet, a dielectric substrate and a ground plane. In contrast, the proposed CPW antenna consists of two layers where the ground structure was designed on the same layer with patch shape.…”

“…The width of the ground gap is referred as Wfg. Furthermore, the optimized dimensions have been calculated by (1)(2)(3)(4) and presented in Table 1. The antenna geometry was calculated using the following equations.…”

“…In this proposed antenna, it is aimed to enhance the expected outcomes from the design mentioned in [2]. The antenna gains in [2] was lower than proposed antenna. It is also a wealthy development that the efficiency can be increased by using CPW structure.…”

“…In [2], a microstrip patch antenna on rubber substrate with defected ground structure (DGS) was designed while, antenna bandwidth at 101 MHz. Enclosed with this bandwidth, antenna showed some positive performances that the improvement of surface current, radiation efficiency and return loss, however it reduced other performances that was lower bandwidth and larger dimensions which ultimately reduced the gain (3.42 dBi) whereas, these performances can be improved by designing a CPW antenna.…”
