Abstract

An apparatus that includes three or more antennas and an integrated circuit selects antennas for use, i.e., for transmission and reception of electromagnetic radiation. The apparatus selects, at a first time, from the three or more antennas, two antennas having approximately the same feed line length so that the two antennas operate at the same phase and at a first angle. The apparatus selects, at a second time that is different than the first time, from the three or more antennas, two antennas having different feed line lengths so that the two antennas selected for use at the second time operate at different phases and at a second angle that is different than the first angle. In this manner the apparatus may change the pattern and/or shape of electromagnetic radiation transmitted by the apparatus by selecting for use particular antennas having different feed line lengths.

Dependent claims

An apparatus comprising:

three or more antennas configured to perform one or more of transmit signals or receive signals, wherein at least two antennas from the three or more antennas have different feed line lengths;
and
an integrated circuit configured to:
at a first time, select for transmission and reception of electromagnetic radiation, from the three or more antennas, a first antenna having a first feed line length and a second antenna having a second feed line length that is approximately equal to the first feed line length so that the first antenna and the second antenna operate at approximately the same phase and at a first angle, and
at a second time that is different than the first time, select for transmission and reception of electromagnetic radiation, from the three or more antennas, the first antenna having the first feed line length and a third antenna having a third feed line length that is different than the first feed line length so that the first antenna and the third antenna operate at different phases and at a second angle that is different than the first angle, and de-select for transmission and reception of electromagnetic radiation the second antenna from the three or more antennas.
