Deepika Verma, K.K. Verma and Chandan
In the article a compact triple band microstrip fed dual L slot rectangular shaped monopole antenna for WLAN/5G/X band applications has been presented. The proposed antenna consists of rectangular shaped with cutting all corner of rectangular and also cutting dual slot inverted each other with microstrip fed has generated multiband operation with good impedance matching 50Ω. A compact proposed antenna size is 27×20×0.8 mm3 and rectangular patch Wp×Lp is 16×16 mm2. The proposed antenna are achieved frequencies range (4.9-5.8GHz) at 5.4 GHz, (5.9-6.3 GHz) at 6.1GHz and (8.5-9.4GHz) at 9.0 GHz and also impedance bandwidth achieved are 16.6% at 5.4 GHz for WLAN, 6.56% at 6.1GHz for 5G and 10.00% for X bands frequency applications and the proposed antenna achieved efficiency more than 90% for each bands. The proposed antenna is act as passive active element with design PCB on FR-4 dielectric substrate and obtained good radiation pattern and surface current distribution, the proposed antenna more compact other than references antenna.
