Design of a Compact Reconfigurable Antenna with Hybrid Polarization and Frequency Control for Geofencing Application

A frequency reconfigurable antenna for location monitoring is proposed. The antenna developed can be reconfigured at two frequencies with suitable polarization and radiation pattern which designed for geofencing application, thus it either can operate at 1.575 GHz band or 2.45 GHz band. The expected outcome of this work is that when the user is within the geo-fence area it will use WIFI, while when the user exits the geo-fence area, GPS application will be selected. With the use of two switches, the antenna can operate either at band from 2.335 GHz to 2.593 GHz for S
11
< -10 dB and from 1.546 GHz to 1.588 GHz at S
11
<-6 dB. The axial ratio results of less than 3 dB is achieved at 1.575 GHz with a bandwidth of 20 MHz.
