In this research paper, compact and slotted patch antenna geometry of size (30.8 × 37.2 mm) has been designed and investigated at frequency 3.30 GHz. The proposed antenna covers 2.08–3.99 GHz frequency band suitable for S-band (2–4 GHz) wireless communication. The proposed geometry of antenna design consist two notches and one vertical
slot. The bandwidth of antenna is enhanced gradually by cutting notches and
slot in antenna patch. The variation made in antenna structure enhanced the antenna bandwidth and antenna resonating at frequency 3.29 GHz near design frequency. The proposed antenna exhibits impedance bandwidth of 62.9% (1910 MHz) resonating at 3.29 GHz with peak gain of 4.7 dB at frequency 3.89 GHz. Resonating frequency band of antenna is applicable for WLAN/WiMAX. Microstrip line fed antenna geometry is fabricated and simulated through IE3D simulation tool.
The slotted waveguide antenna is studied. The basic principles of
slot antenna arrays in waveguides are presented, along with design parameters.
