Study on Airplane Shaped Slit Loaded Microstrip Antenna for Broadband Wireless Application

摘要

A broadband microstrip patch antenna is designed for broadband wireless application in this paper. Simple open-ended airplane shaped slot on the radiating patch top of the infinite ground plane is introduced to achieve broadband. The dimension of the patch is 0.284 λ0 ×0.265 λ0, (λ0 is the free space wavelength at 5.68 GHz). The two simulated frequency bands for the proposed antenna are 0.13 GHz (5.62 - 5.75 GHz) and 2.64 GHz (8 - 10.64 GHz). The measured frequency bands of 0.23 GHz (5.55 - 5.78 GHz) and 2.88 GHz (7.86 - 10.74 GHz) by the proposed fabricated antenna are achieved. The peak gain of 5.89 dBi at 10.5 GHz is achieved. The maximum percentage bandwidth of simulated and measured is achieved with 28.32 and 30.96%, respectively.
