This example demonstrates how XFdtd simulates a 60 GHz cylindrical dielectric resonator antenna that is constructed on a silicon base to emulate on-chip designs. The antenna could be used for a wireless personal area network (WPAN), which would provide communication in the immediate vicinity of a user’s workspace. The antenna has a peak gain of about 2.5 dBi, a bandwidth of over 2.5 GHz, and positive gain of about +/- 55 degrees off boresight.
Higher densities of Radio Frequency (RF) transmitter and receiver antennas on many platforms is a result of the expansion of wireless technology. Knowing the actual antenna to antenna isolation allows engineers to assess the filtering requirements in wireless receivers.

Commercial systems are subject to intense price pressure, making both the purchase cost and the implementation cost of a component important factors in selecting devices for a new design. Another key consideration is likely size constraints and the need to preserve valuable board space.
Compatible with the previously released SKY67183-396LF and SKY67189-396LF, the SKY67181-396LF by Skyworks is a high gain, LNA. Applications include small cells, massive MIMO, macro basestations, and more.
Wireless communication is often taken for granted due to its reliability and effectiveness, but perhaps less so by a soldier whose life may depend upon it. Tactical radios and communications systems must work, and work all the time, even when an enemy may be trying to shut it down with jamming signals and other forms of high-energy electromagnetic (EM) interference. This eBook discusses the importance of radios and other tactical communication systems, and solutions for increasing their performance levels.
