Abstract
In this paper, a planar small size coplanar waveguide (CPW)-fed wideband antenna is presented for wearable applications. The antenna operates for 1395–1400 MHz and 1427–1432 MHz wireless medical telemetry service (WMTS) bands. The center frequencies of the two bands are 1397.5 MHz and 1429.5 MHz. The antenna occupies a volume of 48 mm × 52 mm × 0.8 mm. The simulated and measured reflection coefficients, radiation patterns and gain are calculated and found to be in good agreement, validating the proposed antenna design. The simulation results for SAR and bending are also presented to demonstrate that the proposed antenna operates within the approved limits and can be fabricated on a flexible substrate.
