Bandwidth enhancement of compact and wideband square microstrip patch antenna for WLAN/WiMAX applications in C‐band
Ramesh Kumar Verma
Abstract:This paper presents a compact and wideband square microstrip patch antenna using low cost and easy available FR‐4 substrate of ground size 30 mm × 30 mm (0.51 × 0.51 at lowest resonant frequency 5.07 GHz). The radiating patch of antenna is designed by embedding three T‐shape notches of same dimension formed by two rectangular notches of size 6 mm × 5 mm and 3 mm × 2 mm. The radiating patch is optimized by parametric variation of notches and feed line. The wideband fractional bandwidth (S11 < −10 dB) of 47.2… Show more
