Summary:
This paper discussed antenna size reduction with CRLH - TL metamaterial and partial ground plane techniques. This antenna is designed to work at frequency 3.3 GHz. Two types of antennas working in the same frequency, which are a half wavelength patch antenna and a CRLH - TL Antenna, are designed, simulated, fabricated and measured. From the simulation result of the CRLH - TL antenna, it is shown that a 470 MHz bandwidth with VSWR less than 2 on 3.3 GHz operating frequency, and Gain 1,49 dB can be be achieved; whilst from the measurement result, acquired 250 MHz bandwidth with VSWR less than 2 on 3.3 GHz operating frequency. Therefore, using the CRLH - TL technique a size reduction of 61,11% is achieved. A wide bandwidth antenna is also obtained by reducing the ground plane of the antenna.
