V1.2TBMA4T巨K旦O×DIGITAL SOLUTIONS1 GHz-8 GHz Double Ridged Horn Antenna1 IntroductionCISPR 16 divides the frequency range into several bands and defines specific antennas for each of these bands.For the frequency range above 1 GHz,CISPR 16 specifies using wideband horn antennas for radiated noisemeasurements.Standard wideband hom antennas for EMC applications are quite costly and cover a frequency range far widerthan available on typical low cost EMC pre-compliance spectrum analyzers.In order to provide an antennaoptimized for pre-compliance EMC testing applications above 1 GHz,Tekbox designed the TBMA4 double ridgedhorn measurement antenna.With its moderate price,it is an affordable product for radiated noise EMC pre-compliance testing and generating defined field strengths.The TBMA4 is characterized from 1 GHz to 8 GHz and has a directional pattern typical for double ridged hornantennas.2 Product overviewThe TBMA4 is a small double ridged horn antenna,with its radiating element made from edge plated PCBsubstrate.The housing is made from stainless steel.It is equipped with a standard female N-connector and comestogether with a"pistol-grip"tripod.A standard %thread on the bottom of the antenna makes it easy to connect itto most standard tripods.Furthermore,the antenna is equipped with an indexed mounting plate on its rear.Thisaccessory has a 6mm threaded hole in its centre and radially positioned 4mm threaded holes in 45 steps,typicalfor most horn antennas.1
