Broadband flexible meander line antenna with vertical lines

A novel broadband meander‐line antenna with vertical lines is presented. The proposed antenna has a broadband impedance bandwidth of ∼785 MHz, which covers DCS, PCS, UMTS, WiBro, and WLAN bands. For frequencies across the operating bands, the proposed antenna displays omni‐directional radiation patterns. The proposed antenna has compact dimensions of 12 × 23.1 mm2. The antenna is flexible due to the F‐PCB material used. For these reasons, a cylindrical and folded structure is presented, as transformed from planar. Experimental results using the constructed prototype are presented and discussed.
