Abstract
In this paper, we investigate a new rectangular‐fed printed open‐slot antenna (POSA) with reflector, which has the advantages of improved radiation‐pattern properties along with broad‐bandwidth characteristics. The measured bandwidth of the proposed POSA with reflector is approximately 47.6% (−10 dB ≥ S~11~), thus, it can be used for PCS, DCS, and IMT‐2000. But the measured bandwidth of the PCSA with reflector is approximately 46% (with VSWR ≤ 2.0). The tilt angle at maximum gain is enhanced by using a modified POSA with reflector for practical applications. The radiation pattern null and distortion of the open‐slot antenna exhibited better performances than those of the closed‐slot antenna. The back‐lobe level of the POSA with reflector also presented much better results than the PCSA with reflector. The proposed antenna obtained not only wider bandwidth but also better radiation patterns characteristics than the PCSA with reflector. © 2004 Wiley Periodicals, Inc.
