According to the standard method for calibration of receive antennas to be used in radiated emission measurement below 1 GHz, the sensitivity of receive antenna is defined as a free-space antenna factor obtained by applying a given correction factor to a near free-space factor that is determined by horizontally polarized antenna calibration at a 2 m antenna height. In actual radiated emission measurement...
The incorporation of new services in handheld devices, such as the Digital Video Broadcast—Handheld (DVB-H) operating at the lower ultrahigh-frequency (UHF) band poses a challenge for antenna designers. Wideband small antennas or electrically tunable narrowband small antennas are needed to fulfil the performance requirement. It is well known that below 900 MHz the operation of embedded mobile terminal...
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...
