Inverted L-shaped and parasitically coupled inverted L-shaped microstrip patch antennas for wide bandwidth

Coax‐fed inverted L‐shaped microstrip antennas and parasitically coupled inverted L‐microstrip antennas are presented. The inverted L‐shaped microstrip antenna gives an impedance bandwidth of 30.6%, which is increased to 33.7% by parasitic coupling. The bandwidth has been achieved with a substrate t...

Description
Summary:Coax‐fed inverted L‐shaped microstrip antennas and parasitically coupled inverted L‐microstrip antennas are presented. The inverted L‐shaped microstrip antenna gives an impedance bandwidth of 30.6%, which is increased to 33.7% by parasitic coupling. The bandwidth has been achieved with a substrate thickness of 2 mm. Radiation patterns and gains are also studied and presented. © 2004 Wiley Periodicals, Inc.
