Abstract: A broadband microstrip antenna formed on a printed circuit board has a first planar side comprising a plurality of electrically conductive planar v-shaped antenna segments, each v-shaped antenna segment comprising an open end formed by non-parallel sides and a closed end formed by an intersection of the non-parallel sides. The open end of each v-shaped antenna segment is electrically connected to one or more adjacent v-shaped antenna segments forming a series of electrically connected v-shaped antenna segments. The closed end of a centered v-shaped antenna segment provides a feed point for the one or more adjacent v-shaped antenna segments.

Abstract: Methods for negotiating optimum parameters for communicating between a wireless control device and a wireless user device are disclosed. The methods generally include transmitting a frequency-hopped and spread negotiation signal using network-maximum parameters. The initial parameters make the negotiation signal long-range but low-data. The methods further include adjusting the initial parameters to optimal parameters based on a link budget and data rate requirements received in response to the negotiation signal. The signals are communicated on the 902-928 MHz unlicensed ISM band, and the parameters include spreading factor, output power, and carrier frequency channel bandwidth.
