A Brief Guide to Slotted Array Antennas - Rantec Microwave Systems
The fundamental principle behind a slot antenna is that it functions as the dual of a dipole antenna. In a dipole antenna, current flows through two rods or wires, creating an electric field that radiates electromagnetic waves.

Antenna Downtilt and Coverage Calculator Pasternack The Antenna Downtilt and Coverage Calculator (aka Antenna Tilt Angle Calculator) is used to determine the approximate downward angle, measured in degrees, which the transmitting antenna is to be positioned for optimal signal strength and coverage. It also provides, given a beamwidth, the inner and outer radii of beam's coverage. Free Online EIRP Calculator Pasternack Pasternack's EIRP Calculator determines the radiated power given the transmitter power, the cable loss to the antenna and the gain of the antenna.

Design of CPW-fed asymmetric slot UWB antenna for wireless application | Journal of Electronics (China)
A compact Ultra-WideBand (UWB) slot antenna is presented in this paper. The slot is modified rectangular in shape and asymmetrically cut in the ground plane. A hexagonal patch with two stepped CoPlanar Waveguide (CPW) feed is used to excite the slot. Wider impedance bandwidth is achieved due to the extra inductive reactance created by the asymmetric slot which neutralizes the capacitive reactance of the hexagonal patch. The measured impedance bandwidth of the proposed antenna is 11.85 GHz (2.9–14.75 GHz). The radiation patterns of the proposed antenna are obtained and found to be omni-directional in H-plane and bi-directional in E-plane.
