Abstract:
A multi-band microstrip antenna, based on a cheap FR-4 substrate and with thickness of 1.6 mm is proposed in this paper. A 50 ohm female SMA connector is welded to antenna and the antenna is fed by coaxial cable. The antenna has 8 bandwidths between 2.2 GHz and 11 GHz frequency region. -68.04 dB return loss has been measured at 3.099 GHz in the second bandwidth. Finally, the antenna is used as array elements in 6 different linear and planar geometric arrangements. 17.2 dBi directivity is achieved at 7.9 GHz by 4 elements linear array antenna. The antenna has a simple structure and is suitable for microwave wireless applications such as energy harvesting. The voltage standing wave ratio (VSWR), return loss, radiation pattern and directivity are provided
