This paper presents the evaluation of two antenna designs aimed for a Step Frequency Continuous Wave (SFCW) radar capable of non-invasive fall detection in a pseudo-static radar configuration. The performance of a dual-band rectangular planar monopole is compared against a conductor-backed coplanar waveguide (CBCPW) fed bowtie slot antenna in free space. Two elements of the better performing CBCPW fed bowtie antenna are then combined, separated by a metal plate, and evaluated on the level of SFCW radar operation. It is shown that the performance of the novel CBCPW fed bowtie slot antenna is superior compared to the rectangular planar monopole antenna in terms of person scanning capability. © 2013 IEEE.

Abstract
This paper presents the evaluation of two antenna designs aimed for a Step Frequency Continuous Wave (SFCW) radar capable of non-invasive fall detection in a pseudo-static radar configuration. The performance of a dual-band rectangular planar monopole is compared against a conductor-backed coplanar waveguide (CBCPW) fed bowtie slot antenna in free space. Two elements of the better performing CBCPW fed bowtie antenna are then combined, separated by a metal plate, and evaluated on the level of SFCW radar operation. It is shown that the performance of the novel CBCPW fed bowtie slot antenna is superior compared to the rectangular planar monopole antenna in terms of person scanning capability. © 2013 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
