A magneto-electric antenna (MEA) that uses coplanar waveguide (CPW) to parallel strip (PS) line transition as feed to obtain a wide bandwidth is presented for millimeter wave bands. The balanced feed is utilized to feed a modified ME-dipole. The modified structure consists of a simple two metal strips ME antenna loaded with metallic loops. The resonant modes study shows that a new resonant mode is contributed by the loop when the loop length is nearly a wavelength thereby improving the impedance bandwidth (IBW) and realized gain. A prototype is fabricated in-house with printed circuit board (PCB) technology. Measured results validate fractional IBW (VSWR 2) of 75.76% with realized gain being 8.61.8 dBi for 14 to 29 GHz. The radiation pattern measurements indicate stable radiation pattern across the band with low broadside cross-polarization levels in both E and H planes. The simulated total efficiency is 86-96%.
