- Abstract
In this paper, a compact size, high gain, narrow beam array antenna is proposed for RFID application. A suitable compact size antenna with a gain of 7 dBi is designed as basic element for the array. This base antenna is designed using three slots. Unlike other works, all the three slots are different in shape. Electrical equivalent for this antenna is also proposed to understand antenna working. The same compact antenna is used as basic element to design a 2 x 2 antenna array. A 4:1 feeding network is designed and electrical equivalent of the same is proposed to show power division among the four-radiating patches. Overall size of antenna array is 1.04 λ0 x 1.04 λ0 x 0.029 λ0 mm3. Array's radiation beamwidth is 530 and gain of the antenna array is 10.3 dBi. All the measured results are in good agreement with simulated results. The proposed work is compared with other existing works and is found to be highly compact with excellent gain for the same size.
