Low-profile Magneto-electric Dipole Antenna

Here, a magneto-electric dipole-like antenna is developed for Ku-band (12-18 GHz) applications. A low-profile configuration of a magneto-electric dipole antenna has been obtained by the planar arrangement of four shorted patches and L-shaped coax probe. The antenna shows a broad bandwidth response with stable gain and radiation characteristics. The antenna executes an impedance bandwidth between 13.3 and 16.7 GHz with two resonances at 13.9 and 15.6 GHz frequencies. Finally, the antenna has been fabricated and its performance experimentally verified which shows a good agreement with simulated results. The experimental results show -10 dB bandwidth of 11.56%; and peak gain values of 3.9 and 4.6 dBi at 14 and 15 GHz, respectively. On account of the single-layered printed substrate, the proposed antenna can be easily assimilated with associated circuitry.
