Allowed eight wood (Quasi-Yagi) antenna is a kind of based on the traditional wooden antenna broadband plane eight microstrip antenna, have good gain characteristics.
The simulation and test the results show that: must have eight wooden antenna realize effectively ultra-wideband, miniaturization, high power gain, and in a horizontal antenna energy radiation range is fairly large, and in vertical direction energy radiation relative concentration, thus in the distance the ground communication effectively increase the utilization rate of radiant energy, may realize the directional distance ground broadband communication
Based on the structure of the eight wooden antenna is designed and produced a prospective eight wooden type broadband high power gain microstrip antennas, using 3 d electromagnetic simulation software (Ansof t HFSS) simulation software, in the light of the single to the structure, and on the basis of the number by adding to realize the high power gain and more wide bandwidth. The actual test show that the antenna working band in 4. 8 ~ 6.4 GH z, 5.6 GHz place in the center frequency, peak gain of around 10.2 dB, than before and after about 21 dB, and the simulation results with the experimental data.

Yagi (Quasi-Yagi) antennae are a based on traditional broadband Planar microstrip antenna Yagi antenna, with good gain characteristics.
Simulation and test results showed that effectively Yagi antenna for ultra-wideband, small size, high gain, and in the horizontal direction of antenna energy radiation than larger, and relative concentration of energy radiated in the vertical direction, resulting in a long distance communications effectively increases the utilization of radiant energy in the ground, you can implement a directed distance terrestrial broadband communication
Based on structure design of Yagi antennas and produced a high gain Yagi-type wide-band microstrip antenna using three dimensional electromagnetic simulation software (Ansof t HFSS) for design simulation, on top of the existing structure of lead single, by increasing the number of Director to achieve a high-gain and wide bandwidth. Practical tests showed that antenna frequency band 4. 8~6.4 GH z, in the Center frequencies 5.6 GHz, peaking approximately 10.2 dB gain, than before and after ~ 21dB, and simulation results of basic line.
