Compact and Broadband Uniplanar Yagi MSA for Sub-6 GHz 5G Frequency Band

A compact and broadband Yagi MSA is proposed with a simple feed to achieve endfire radiation for a frequency band of sub-6 GHz 5G. To make the antenna compact along the boom length, the concept of a microstrip antenna is used so that the distance between the reflector and the driven element is reduced significantly. To increase bandwidth, a semi-elliptical driven patch is used instead of a rectangular driven patch. A parametric study of various parameters of the antenna is carried out to see their effects on the gain, bandwidth, and radiation pattern of the antenna. The proposed antenna having size 0.50 lambda(0)x0.13 lambda(0)x0.009 lambda(0) provides a better figure of merit with a peak gain of 5.2 dBi, an average gain of 4.9 dBi, and 11.3% bandwidth.
