Low Profile Wide Slot Antenna with Conical Beam for Indoor Wireless Communication

A new kind of low profile wide slot antenna with conical beam is designed. Through optimal designing, gain at 5.8 GHz can achieve 6.73 dBi, the gain is in the range of 6.16-6.76dBi in the frequency band of 9.31%. In addition, the contour of the 2D pattern of the antenna at
$\theta_{\max}=31^{\circ}$
is similar to a square at 5.8 GHz, which is more suitable for the indoor wireless communication in cuboid environment.
