Abstract
In this paper, a modified log spiral antenna for multi-band application with co-axial feed mechanism is proposed. Two optimized Slots Ring Resonators (SRR) have been added around the log spiral antenna to expand bandwidth at low frequencies without increasing its initial size. The proposed antenna operates in the frequency range of 0.7 GHz-1GHz/1.1GHz-1.4GHz/1.5GHz-3GHz. The proposed antenna shows omnidirectional pattern in elevation plane and dipole type radiation pattern characteristics in azimuthal plane. Gain of the proposed antenna lies between 3.5 dBi–5.1 dBi. The Antenna is fabricated on FR4-epoxy substrate of dimension 116 × 116 × 1.6 mm3. Simulation and analysis of the proposed structure has been carried out by using HFSS EM simulation software. Simulation results have been confirmed in measurement. The presented structure can be utilized for RF energy Harvesting for GSM-900 (921 to 960 MHz), GSM-1800 (1805 to 1880 MHz), UMTS (2110 to 2170 MHz) and Wi-Fi (2400 to 2480 MHz).
