Abstract
This paper addresses a fundamental issue regarding electrically small antennas. In conventional cases electrically small antennas suffer the fundamental limit of high Q and can not be used for broadband radiation. However, by integrating high-speed switch devices on the antenna, it is found that the bandwidth limit on the radiation can be overcome. This is because the high-Q value associated with electrically small antennas no longer limits the bandwidth of radiation in such a time-varying system
