摘要：

In this communication, an ameliorate textile circularly polarized (CP) rectenna for harvesting the emitted RF energy in INSAT band is presented. The textile antenna is bendable, robust, and low mass so that it can be weaving into clothes of the smart soldier to charge the portable electronic devices in the battlefield. Weight burden on the soldiers is significantly reduced; indeed power handling capacity is increased by integrating the textile rectifying antenna into soldier clothes. The proposed textile rectenna has a 10-dB return-loss bandwidth of 1200 MHz (6.6-7.8 GHz) with the maximum gain 8.14 dB an overall size of 50 x 50 1.076 mm(3). This antenna is suitable for INSAT band (6.725-7.025 GHz) RF energy harvesting operations. Measurement results are also shown with theoretical predictions, both of which are in quite good agreement.
