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.

Answer 1

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。
