Abstract
A phased array antenna includes a first transceiver, a plurality of first radiating elements that are arranged in a first linear array, a first feed network electrically interposed between the first radiating elements and the first transceiver, and a first switch that is coupled along the first feed network, where a state of the first switch is selectable to adjust a number of the first radiating elements that are electrically connected to the first transceiver.

A phased array antenna, comprising:
- a first transceiver;
- a plurality of radiating elements;
- a first feed network electrically interposed between the first radiating elements and the first transceiver;
- a first switch that is coupled along the first feed network;
- wherein a state of the first switch is selectable to adjust a number of the first radiating elements that are electrically connected to the first transceiver,
- wherein the first switch is connected to a transmission line segment of the first feed network and is located at an electrical distance of approximately [0.25+(n*0.5)]λ, from a junction where one of the radiating elements connects to the transmission line segment, where n is an integer having a value of 0 or greater and λ, is a wavelength corresponding to a center frequency of the frequency band of operation of the phased array antenna.
