Abstract

A wideband coplanar waveguide (CPW)‐fed two‐arm spiral slot antenna without a balun circuit is presented in this article. Phase progressions at arm ports are realized through the coplanar waveguide excitations. A detailed characterization of all antenna components and parameters is provided along with guidelines and recommendations for broad bandwidth and small reflection. Variations of the impedance matching due to the turn numbers, the ground width separated between two neighboring turns and the slot width are tested and studied. The measured impedance bandwidth of a S~11~ ≤ 10 dB ranges from 1.63 to 8 GHz and covers most of the commercial wireless communication systems, such as DCS, PCS, IMT‐2000, WLAN, Bluetooth, and HIPERLAN. © 2008 Wiley Periodicals, Inc.

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
