The antenna structure may be a GPS patch antenna, or any other antenna adapted to receive broadcast signals. The ground plane is made from radar absorbing material (RAM) in electrical contract with conductive radials. The RAM inherently acts to suppress surface currents on the ground plane, ...
PURPOSE: An antenna and method for manufacturing the same is provided to serve beamwidth control by mechanically adjusting the reflector angle. CONSTITUTION: The electrical device patch antenna includes a patch element(32), a finite ground plane(34), and a microstrip feed line(36) lying on parall...

Improving radiation-pattern distortion of a patch antenna having a finite ground plane This paper presents a very useful and yet simple method of improving the radiation-pattern distortion of a patch antenna having a finite ground plane. The ......
A microstrip patch antenna (MPA) has been fabricated using a conducting polymer, polypyrrole (PPy), as a ground plane. The bulk conductivity level of the PPy ground plane is 2000 S/m and its thickness is 330 mum. The antenna is designed to operate in the 11 GHz region. The measured and...
Data transfer of passive RFID systems at UHF frequencies is based on backscattering: tag antenna reflects back a part of the energy received from reader. That reflected energy is also modulated by the microchip of a tag. 展开 会议名称: IEEE Antennas and Propagation Society Symposium: June 20-...
A patch antenna is also known as a panel, flat panel or microstrip antenna. Techopedia Explains Patch Antenna A patch antenna has a curved path of coverage; hanging on a wall, it can spread to a width of 30 to 180 degrees. This type of antenna is usually lightweight and can be easily...
正規設計patch antenna的步驟,patch size與ground plane size並非任意畫,再靠模擬軟體最佳化,事實上是有式子可以計算的。首先,利用下面公式,由介電係數與天線操作頻寬(諧振頻點),先算出patch寬 再用以下的式子,定義出適合的ground plane size;(ground plane的長與寬,要大於patch size六倍板厚) ...
antenna. This paragraph is critical to understanding the patch antenna. The current adds up in phase on the patch antenna as well; however, an equal current but with opposite direction is on the ground plane, which cancels the radiation. This also explains why the microstrip antenna radiates ...
