Abstract
Various embodiments that pertain to a loop antenna are described. The loop antenna can be a single loop antenna that switches between a first phase and a second phase. While operating at different phases, the loop antenna can function at the same frequency. The loop antenna can observe a response to the frequency at the first phase and the frequency at the second phase. This can provide a wider range of information over operation in a single phase.

A system, comprising:
- a single loop antenna that comprises a first half of about 180 degrees and a second half of about 180 degrees;
- and
- a hardware switch set that causes the single loop antenna to operate at a frequency and a first phase during a first time and operate at the frequency and a second phase during a second time,
- where the hardware switch set comprises a first energy circuit coupled to a first end of the first half and a first end of the second half, and
- where the hardware switch set comprises a second energy circuit coupled to a second end of the first half and a second end of the second half,
- where the first energy circuit is to energize the single loop antenna,
- where the second energy circuit is to energize the single loop antenna,
- where the first energy circuit, the second energy circuit, the first half, the second half form a continuous loop.
