Abstract
This paper presents a novel gap coupled suspended multiband microstrip antenna suitable for wireless applications like long term evolution (LTE), wireless local area network (WLAN), Amateur radio, and Sub 6 GHz 5G wireless applications. The proposed antenna is a single layer geometry suspended in air that employs a gap-coupled feed with a parasitic strip for tuning the input impedance. The overall dimensions of the antenna are 41.4 mm x 39 mm x 3.12 mm. The presented antenna offers a total of six resonant frequencies centered at 1.70 GHz, 2.77 GHz, 3.03 GHz, 4.26 GHz, 4.58 GHz, and 5.64 GHz. Measured resonant frequencies fairly match the simulated values. Further, the gain values at these frequencies are 7.29 dBi, 6.10 dBi, 7.39 dBi, 5.39 dBi, 6.22 dBi, & 7.03 dBi, and the corresponding measured gain values are 6.92 dBi, 7.72 dBi, 4.88 dBi, 5.34 dBi, 4.25 dBi, and 6.51 dBi, respectively. Radiation patterns were measured at all these frequencies and found to have highly stable radiation characteristics except for slight asymmetry at the high frequency end of the operational band.
