This paper presents a novel biconical broadband antenna which is used for EMC test application, compared with the conventional biconical antenna the proposed antenna is small in size and good in electrical characteristics, its voltage standing wave ratio (VSWR) is less than 4 within the frequency range of 500 MHz ~ 2500 MHz. The antenna can be used to measure the shielding effect of a shielding box...
In this paper, we present a time-varying matching design for electrically small antennas in pulse-based systems. The proposed technique is applied to small loop antennas in the receiving mode. Simulated results show that substantial improvement in the overall antenna efficiency can be achieved without dispersion that is one of the major limitations of a conventional matching network of equivalent...
