Study of an Impact-resistant Wide Bandwidth Micro Strip Antennas Carried By Missile

摘要

The micro strip antennas are widely applied in the measurement and communication, but to the micro strip antennas, the most serious flaw is that the band width of signal patch antenna is narrow individually. Compared to the oscillator antenna, the slot antenna, and the waveguide horn antenna and so on, which work bandwidths are in 15%~50% ，The bandwidth of micro strip signal patch antenna is only several percent, so it is advantageous that spread the frequency band of the micro strip antennas for receiving and dispatching 。Monitoring the projectile flight posture by the radio is the premise of attacking the target precisely, positioning the falls of the test vehicle is one effective method of recycling the experimental missile 。This paper promotes one kind of wideband micro strip antenna array used to launch and receive the command signal, which based on the application background, taking the missile as the carrier. Studies use the simulation technology to simulate the antenna array directional diagram. Result demonstrates the plan is feasible.
