A printed edge-fed counterpart of the wire Bruce array antenna, for frequency scanning applications, is presented in this paper. The unit-cell of the proposed antenna consists of bowtie and semi-circular elements to achieve wide bandwidth from below 22 GHz to above 38 GHz with open-stopband suppression. The open-stopband suppression enables a wide seamless scanning range from backward, through broadside, to forward endfire. A sidelobe threshold level of −10 dB is maintained to evaluate efficient scanning performance of the antenna. The antenna peak realized gain is 15.30 dBi, and, due to its compact size, has the ability to scan from −64° to 76°.

Two compact 2.4-GHz meander-line antennas suitable for integration with the printed circuit board(PCB) of a on a universal serial bus(USB)-WLAN card are presented in this paper. These antennas have been designed with size reduction up to 67% compared with the previous reported design. The CST Microwave Studio TM EM simulator is employed for design evaluation. The printed meander-line antenna is realized on a FR-4 PCB substrate. The simulated VSWRs are less than 2 from 2.4 to 2.5GHz.
