A Millimeter Wave Microstrip Antenna Array with Harmonics Suppression Elements
Antenna element and array with harmonic suppression ability are desired in compact and integrated RF front-end systems,because they can lead to remove the additional bandpass filter. This paper presents a microstrip antenna element with the operation frequency of 35GHz. A good second order harmonic suppression performance is obtained by a compact co-planar structure. A Ix4 array constructed by this element is also studied. The antenna array is fed by a corporate-feed network without using quarter-wavelength impedance transformers. Element and array gain of 5.4dB and 11.4dB are achieved,respectively. Compared to the traditional antenna array,the studies indicate that the array obtains a gain suppression of 9.1dB and 7.0dB at the frequency of 46GHz (corresponding to TM11 of the reference antenna array) and the second order harmonic frequency of 70GHz,respectively.
