摘要：
The design of a dual band operational compact antenna is investigated in this paper for RFID handheld reader application. The dual frequency operation of the antenna is achieved by using a U-shaped slot on the patch and a L-shaped slot in the ground plane. The shorted wall connecting the patch and the ground plane plays a vital role to make it compact. The overall dimension of the patch is 20x36 mm2 which is very compact with respect to the operating frequencies. Moreover, the air gap between the patch and the ground plane provides the circuitry to be embedded within the antenna. The antenna achieves a -10 dB impedance bandwidth of 12 and 10.4% respectively covering all sub-bands of universal UHF and ISM 2.4GHz bands. The antenna is seen to operate with linear polarization with stable omni-directional radiation characteristics in both E- and H-planes.
