Summary:
A high gain planar array operating over the entire 802.11a WLAN band of 5.15 to 5.825 GHz is required to provide range extension for WLAN access points. In addition, a low profile and light weight planar array would improve its portability as well as the aesthetic aspect at its site of deployment. To satisfy these requirements, we have developed a very thin C-band array with dimensions of 18 x 18 x 0.65 cm possessing a symmetric main beam with peak gain of 20.3 dBi at mid-band. The cross-polar level is less than -30 dB and the decaying sidelobe structure is well behaved. The design of such an array is discussed below.
