Title: Plane antenna
Inventor: YAMAMOTO HIROHIKO
IPC: H01Q23/00
Filed: 1987-08-07
Abstract: PURPOSE:To improve the gain and efficiency by forming a feeder circuit to a radio wave radition element by at pleast plural power combination circuits each comprising a microstrip circuit and plural low noise amplifiers including active elements and connecting the low noise amplifier between the input and output of the power combination circuits, thereby preventing the reduction in the efficiency due to the loss of the feeding circuit. CONSTITUTION:The output of the feeding circuit 4a connects to the input of a low noise amplifier 5 respectively. The low noise amplifier 5 is an amplifier including an active element such as a FET and a bias power is supplied from an antenna rear face or the like through a through-terminal or the like and amplifies an input signal. A circularly polarized wave signal received by a radio radiation element 1 is combined by the feeding circuit 4a and led to the low noise amplifier 5. A weak signal inputted to the low noise amplifier 5 is amplified by the low noise amplifier 5. In arranging the low noise amplifier 5 in such a way, the loss of the feeding circuits 4b, 4c after the low noise amplifier 5 is cancelled by the gain of the low noise amplifier 5 and the effect of the transmission loss of the low noise amplifier 5 is excluded and the antenna gain is improved.
