Abstract :
A new microstrip antenna array with series-fed patches is proposed. To reduce the length of feeding lines the `through-element´ feeding technique has been developed. A microstrip patch in which the input feeding line is directly connected and the output line is coupled to a patch is investigated. By adjusting the length of the coupling region an appropriate coupling level is achieved. A 4 × 1 antenna array operating within the 24 GHz frequency band for radar sensor applications is designed using the proposed feeding technique
