Variations of Coplanar Waveguide fed elliptical patch microstrip antennas with elliptical slot ground plane in 4000 MHz frequency band is proposed. The first variation of elliptical shaped microstrip antenna yields impedance bandwidth of more than 117% that covers Wi-MAX and WLAN bands. Further another variation in which elliptical patch and elliptical slot ground plane rotated by 900 is proposed...
The variations of Coplanar Wave guide fed hexagonal micro strip antennas with hexagonal slot ground plane are proposed in 3000 MHz frequency band. The first variation of hexagonal shaped micro strip antenna yields impedance bandwidth of more than 108% which covers Wi-MAX and WLAN bands. The hexagonal shaped patch is rotated in 300 backed by the same ground plane. This configuration yields higher bandwidth...
The broadband microstrip antenna is realized by fabricating the patch on lower dielectric constant thicker substrate. The proximity feeding is a more commonly used technique to realize broadband microstrip antennas for substrate thickness greater than 0.06λ0. In the proximity fed configuration the coupling rectangular strip is either placed below the patch or it is placed inside the slot which is...
