Abstract :
The key characteristics of the planar UWB chip antenna are summarized in the following: This chip antenna has a low profile, light weight, and compact size. Antenna patterns are omnidirectional, linearly polarized and with high efficiency. The input has 50Omega characteristic impedance and is impedance-matching free with a wide bandwidth. It can be surface-mounted for a compact SMD package. With the LCP insert molding technology, this chip antenna is highly stable with variations in temperature and humidity, and also very cost-effective to have superior performances for applications in the lower commercial band of the UWB system. This chip antenna can be embedded in a variety of portable devices.
