A wideband antenna is designed and implemented by using air filled stacked structure on thin PTFE substrate for millimeter wave personal network area (WPNA) application. The optimized antenna achieves more than 22% impedance bandwidth and more than 9 dBi gain over the frequency band 57 – 66 GHz.
In this paper, stacked patch antenna with different topologies fabricated on 0.127 mm-thick substrate were investigated and measured. It was found that the bandwidth and gain of stacked antenna fabricated on 0.127 mm-thick substrate are less than that on 0.254 mm-thick substrate. To increase the frequency bandwidth, a small slot is inserted into the lower substrate driving patch to cover at least...
Recent years, more and more intensive researches have been done widely for the application of high speed, short distance millimeter wave wireless personal area network (mmWPAN) in the unlicensed frequency band of 60GHz. An antenna with high gain (more than 10dBi) is expected in such a system to provide enough link budgets and compensate high propagation loss. Most of the researches were focused on...
Beam steering antenna is expected in 60 GHz wireless communication system to improve the signal to noise ratio and obtain high gain with wide cover range for high speed WPAN application. In this paper, patch antenna arrays with planar topology are investigated by synthesizing the network losses and devices such as phase shifters. The investigation results can provide a valuable guide line for the...
