A HIGH GAIN ANTENNA ARRAY FOR WIRELESS HANSETS

Abstract

The paper proposed an antenna array consisting of four bow-shaped dipole elements. The antenna array operates at a center frequency of 5 GHz with a bandwidth of 332 MHz. By utilizing the reflector and the directors, the antenna obtains a high gain of 10.6 dBi at 5 GHz and over 10.3 dBi across the operating bandwidth. Meanwhile, the antenna array still obtains a compact size of 134 × 60 × 0.8 mm³. The antenna is designed on RO5880 substrate and simulated by CST studio software. The antenna can be suitable for stations in Indoor Positioning Systems, or transceivers as handsets for long distances.
