Improved Wide-band Dual-linear Polarization Compact Microstrip Antenna Array for Microwave Image System
This paper provides a wide-band dual-linear polarization compact antenna array for P-band Microwave Image system, where the center frequency is 400 MHz with a 200 MHz of bandwidth (50% from 300MHz to 500MHz), and the size is smaller than 1600mm×400mm. The array system has dual-linear polarization with a maximal gain of 14.3dB at the center frequency, a minimum gain of 10.2dB at two ends of the band and the cross-polarization level is much less than -50dB over the frequency band. In the antenna design, compactness and stability of the presented antenna array is considered firstly, which is very important in practical airborne environment. Furthermore, one of the most excellent achievements is to develop a simple wide-band match structure composed with three independent parts.
