Centre frequency.The antenna is imprinted on a very small substrate.
Background technology
Antenna is the indispensable part of institute's wire/wireless communication system, carries the form that the signal for sending emitter changes into electromagnetic wave
With to spatial, or the electromagnetic signal in free space is changed into high-frequency signal so that receiver is received, so as to realize radio communication
Spacing wave exchange process.With continuing to develop for wireless communication technology, hardware researches and develops the continuous progress of condition, in order to nothing is better achieved
The transmission of line signal, to it is also proposed requirement higher in the performance of antenna, under the wide variety of overall situation of current Wireless Telecom Equipment,
The importance of antenna is even more growing day by day, various antenna technologies research and technical indicator higher requirement cause antenna technology welcome and
One major opportunity of development.
