ABSTRACT In this article, a novel super‐wideband planar microstrip‐fed monopole antenna is investigated and designed. The antenna consists of a well‐optimized hut‐shaped radiating patch having a diamond‐shaped slot window at its center. To achieve nearly omnidirectional pattern, a partial ground plane consisting of an optimized slit exactly on the opposite of the feed line is used. Measurement results show that the impedance bandwidth for |S 11 | dB ≤ 10 dB is enhanced largely to 184.5% with a ratio bandwidth more than 24.8:1 (0.9 − 22.35 GHz). This, together with its nearly constant measured gain of 3.35 dBi ±1 dB over this entire band makes it a potential candidate for both ultra‐wideband and super‐wideband applications. Moreover, the proposed antenna has a compact size of 40 × 25 mm 2 on 1.6 mm thick FR4 substrate with dielectric constant of 4.4. Details of the proposed antenna are described, and both theoretical and experimental results are presented. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2645–2649, 2015
