✦ Synopsis

A CPW-fed bow-tie slot antenna is presented. Experimental results show that the widest bandwidth can be adjusted by the slot width when the extended angle is zero, while the far field is in the broadside direction and the cross polarization is kept at a low le¨el. The ( ) bow-tie slot antenna can obtain at least 36% bandwidth VSWR -2 with a 20Њ extended angle. A smaller slot width needs a larger extended angle to reach the widest bandwidth; meanwhile, the far field has a wider 3 dB beamwidth in the H-plane than that using a larger slot width.

Adjusting the slot width in a slot antenna can determine the operating frequency bandwidth. In order to obtain a wider radiation beamwidth, a narrower slot width is needed. This paper uses a CPW tuning stub in the CPW-fed slot antenna to achie¨e this goal. ᮊ 1998
