A novel kind of optically transparent, low cost and wideband water patch antenna is demonstrated and analyzed. A significant feature of the proposed linearly polarized antenna is that both the patch and the ground plane are made of water. Thus, the whole structure becomes optically transparent except the small central feeding probe. The main radiators are made of water, which is available everywhere,...
In this paper, two investigations of transparent patch antennas are demonstrated. One is using the liquor serving as the antennas while another is the study of the temperature influence of the distilled water on the antenna's radiation performances. The measured results show that the liquor has wide impedance bandwidth of more than 30% for |S11| < − 10 dB and the temperature variation of the water...
A new kind of water patch antenna for omnidirectional radiation pattern is proposed and designed. Different from the previous water patch antenna model, this kind of water patch antenna is completely made of distilled water except for the feeding probe. Results show that an impedance bandwidth of 40.5% for SWR < 2, a gain up to 4.8 dBi at maximum radiation direction and omnidirectional conical...
A novel kind of water patch antenna for conical beam application is designed and analyzed. The difference between this antenna design and traditional conical beam antenna design is that the pure water is utilized to serve as radiation patch instead of the metal patch. The pure water patch is excited by a disk-shaped probe to achieve wide bandwidth. The simulation and measurement are carried out and...
The first demonstration of a four-port integrated polarizing beam splitter is reported. The device was fabricated on a silicon-on-insulator platform and exhibits crosstalk level < −10dB over a 150nm bandwidth.
