A Novel Stacked Rectangular with Surface Mounted Short Rectangle Dielectric Resonator Antenna in C-Band Applications

A novel stacked rectangular structure with surface-mounted short rectangle dielectric resonator antenna (SRSMSR) with an E-shaped microstrip feed through a wide aperture slot was investigated for C-band operation in wireless communication and tracking radar applications. The developed design uses copper for SMSR to improve return loss up to -46 dB, gain up to 10.7 dB, and an observed impedance bandwidth of 20.6% in the broad frequency range of 5.69 GHz-7.0 GHz. The 3 dB beamwidth achieved in the E-plane is 89.82 degrees, while that in the H-plane is 24.31 degrees.
