Substrate integrated waveguide (SIW) slot array omni-directional antenna with balanced feeding;

Design of a L-band omni-directional antenna for electronic warfare decoy;

Traditional horizontal polarization waveguide double-slot omni-directional antenna arrays have various disadvantages,such as narrow bandwidth and high cost.

According to the structural characteristics of Wireless Sensor Network(WSN),a novel range-free and distributed positioning algorithm(PBSAO) is proposed based on anchor s sectored antenna and sensor s omnidirectional antenna.

The calculation result shows that this kind of configuration could resolve the problem of non-circle degree,which usually occurs in the omnidirectional antennas.
