HPBW:The half power beamwidth (HPBW) can be defined as the angle subtended by the half power points of the main lobe.
Main Lobe:This is the radiation lobe containing the direction of maximum radiation.
Minor Lobe:All the lobes other then the main lobe are called the minor lobes.These lobes represent the radiation in undesired directions.The level of minor lobes is usually expressed as a ratio of the power density in the lobe in question to that of the major lobe.This ratio is called as the side lobe level (expressed in decibels).
Back Lobe:This is the minor lobe diametrically opposite the main lobe.
Side Lobes:These are the minor lobes adjacent to the main lobe and are separated by various nulls.Side lobes are generally the largest among the minor lobes.

HPBW(半功率射束宽度):半功率射束宽度可以用主瓣中的半功率点所对应的(包含的)角度来描述.
主瓣: 它是一个辐射波瓣,其中含有最大辐射的方向.
副瓣: 除了主瓣其它所有的瓣都被称作副瓣,这些副瓣展示的都是不必要的辐射或没有用方向的辐射.通常,副瓣的等级量用所述瓣中的功率密度与主(波)瓣的功率密度(这二者)的比值来描述.这个比值叫做旁瓣电平(以分贝数表示).
后瓣: 这也是一个副瓣,它正好与主瓣相反(所对的方向相反).
旁瓣: 旁瓣也属于副瓣,并与主瓣毗连.而且这些旁瓣还可以被各种无意义的密码(如零位,清空等)给予分离(出来).一般而言,旁瓣在副瓣中站的比例量是最大的.
