“…This limitation can be overcome by using half-mode substrate integrated waveguide (HMSIW) or quarter-mode substrate integrated waveguide (QMSIW) techniques. 14,15 Both HMSIW and QMSIW support the same field distribution of FMSIW congruence. Therefore, the antenna size can be miniaturized to one-half with the armament of HMSIW methodology and one-quarter with the armament of QMSIW methodology, while preserving the same performance of FMSIW.…”

“…Although, this technique is feasible to acquire optimal performance, but the size of the antenna is bulky owing to the full‐mode substrate integrated waveguide (FMSIW) geometrical topology. This limitation can be overcome by using half‐mode substrate integrated waveguide (HMSIW) or quarter‐mode substrate integrated waveguide (QMSIW) techniques 14,15 . Both HMSIW and QMSIW support the same field distribution of FMSIW congruence.…”

A multiband half‐mode substrate integrated waveguide (HMSIW) slotted antenna is developed for ISM/WiMAX/WLAN applications. HMSIW technique has been utilized to acquire antenna compactness. Two inverted L‐shaped slots of half wavelength are embedded onto a HMSIW rectangular cavity for attaining a hybrid mode (i.e., Half‐mode of Half‐mode of ), which induces a lower resonance at 2.4 GHz. An inverted L‐shaped slot is influenced to radiate hybrid mode at 2.4 GHz, while the innermost inverted L‐shaped slot radiates modified mode at 3.30 GHz. A multiband is obtained by amalgamation of hybrid mode (at 2.4 GHz), modified mode (at 3.30 GHz) and modified mode (at 5.38 GHz). The radiating modes are elucidated by using mode theory methodology for ascertaining the resonance characteristics of the prototype antenna. The antenna parameters have been optimized by artificial neural network technique using MATLAB. The antenna geometry possesses a shrinkage size of 30 × 16 × 1.6 mm3, which has been designed on FR‐4 substrate. To vindicate the simulated consequence, the fabricated prototype has been tested. It contributes the fractional bandwidth of 6.4% (2.09−2.23 GHz) in the hybrid mode at 2.18 GHz, 9.03% (2.89−3.17 GHz) in the half cavity mode at 3.10 GHz and 9.96% (5.11−5.65 GHz) in the half cavity mode at 5.42 GHz, respectively, which is beneficial for ISM, WiMAX and WLAN band wireless applications.
