Broadband antenna array for wireless communications

A broadband antenna element for wireless communications, the antenna element comprising:

• one or more radiator conductors configured to receive an electrical current and to transmit a polarized electromagnetic (EM) wave;
• a feeding mechanism configured to feed an electrical signal generated by a transmitter into the one or more radiator conductors;
• and
• a ground conductor coupled to a ground potential of the transmitter,
• wherein:
• the one or more radiator conductors, the feeding mechanism, and the ground conductor comprise conductors of a multilayer substrate, and
• the antenna element is configured to transmit with a bandwidth of at least approximately 10 GHz centered at a predetermined center frequency.
