Abstract

This paper presents a systematic development of microstrip patch antennas for WiGig applications. The size of the antenna is enlarged via the use of high-order mode operation. Shorting pins and slot on the radiating patch are employed to eradicate the associated grading lobes and narrow bandwidth. Symmetric radiation pattern, higher gain and lower cross-polarization level are realized by differentially feeding two mirrored, shorted higher-order mode patches. On the other hand, a single feed antenna with 25% bandwidth is achieved by integrating two mirrored elements into a single antenna.
