Abstract

The manuscript reports a simple reconfigurable inset-fed Microstrip patch antenna using defected ground structure (DGS). The DGS serves two folds in the proposed design; first it eliminates the higher order resonance and second, supports the resonance at other band with the incorporation of switching diode in it. Initially, the patch antenna has been designed to operate at 5.6 GHz. With the incorporation of the switch, a resonance at 3.36 GHz was obtained. The measured prototype shows a return loss (S11) better than −12 dB in each case with a gain of 4.2 dBi and 2.2 dBi at ‘OFF’ and ‘ON’ condition, respectively. The proposed antenna is specially designed to cater the needs of portable human non-invasive vital sign detection (NIVSD) system for medical and defense applications. Low cost, high directivity and light weight are desired for antenna used in these applications.
