Method and system for a sub-harmonic transmitter utilizing a leaky wave antenna
View Patent ↗Methods and systems for a sub-harmonic transmitter utilizing a leaky wave antenna are disclosed and may include transmitting wireless signals at a harmonic frequency of a source signal utilizing one or more leaky wave antennas (LWAs) in a wireless device including one or more transceivers on a chip. The LWAs may be configured with a resonant frequency at the harmonic frequency. The source signal may be communicated to the LWAs utilizing a power amplifier, which may be operated in switching mode thereby generating a square wave from the source signal. The LWAs may be integrated on the chip, on a package to which the chip is affixed and/or on a printed circuit board to which the chip is affixed. The harmonic frequency may be three times a frequency of the source signal. The transmitted wireless signal may be amplitude modulated utilizing a bias voltage applied to the LWAs.
