Novel micromachined patch antenna for mobile communication
The rapid development of wireless communications worldwide results in a huge demand forminiaturized antenna with excellent performance to send and receive wireless signals to and from com-munication devices. Microstrip patch antennas are used in a variety of applications for their salient fea-tures. By sandwiching a layer of Teflon between the silicon wafer and the ground plane
the novel mi-cromachined shortened stacked patch antenna printed on high-index wafer has superior performance o-ver those of traditional design
while its bandwidth has been increased by as much as 8.6 %
and itslength of patch has been miniaturized to only an eighth wavelength. The radiation patterns show thateven if the antenna is on a ground plane of approximately the size of a handset phone circuit board
most of the radiation is directed away from the user's head
and the wide beamwidth can ensure wideangular coverage. The antenna micromachined in a silicon wafer can also be integrated with Si andGaAs IC without affecting any of the circuit requirements.
