N2 - In this paper, a novel antenna system for wideband detection of target information is presented. The proposed antenna system consists of a receiving antenna, a low noise amplifier, and a transmitting antenna. A 0.254 mm thick FR4 epoxy dielectric substrate with the dimension of {mathrm {20 mm times 20 mm}} is applied. The two monopole antennas are placed orthogonally to realize polarization isolation. The low noise amplifier can be utilized to amplify the RF signal of the system and reduce the clutter interference of the system. To decrease the overall size of the antenna system and broaden the frequency band, the ground plane with protruded rectangular strips and coupled pi-shaped strips is used. The compact antenna system can meet the requirement of being mounted on the bird. The receiving antenna receives the signal from the small target of the radar transmitter, the received signal is amplified through the low noise amplifier to meet the requirement of transmission power, and then the signal is radiated into free space through the transmitting antenna, which makes the radar receiver in a certain area receive the proper signal level. The proposed antenna system obtains a-10dB bandwidth of 2.75 GHz (15.52-18.27GHz). In the operating band, the two antennas have low mutual coupling of lower than-20dB. The results show that the peak gain level of 18.47 dBi of the antenna system is realized. The proposed compact antenna system, with the advantages of simple design, wide bandwidth, improved isolation, and enhanced gain, provides a promising solution to detect the small target information and target information of long distance.
