In this Letter, a compact dual-band dual-mode microstrip-fed dipole-loop (MDL) element is proposed, which consists of a rectangular loop-structure embedded in the feed-line of a printed dipole. This MDL element exhibits an additional one-wavelength loop resonance at a lower frequency (1.55 GHz) with omnidirectional pattern, along with the conventional reflector-backed half-wavelength dipole mode (2.55 GHz) having end-fire radiation. Thus, electrical size reduction and dual-band frequency-dependent pattern diversity characteristics are obtained simultaneously in the MDL element. Furthermore, the proposed MDL element is used to construct a 1 × 2 array which operates at 1.45 and 2.59 GHz with impedance bandwidths of 14.33 and 12.92%, respectively. Bi-directional broadside radiation (peak gain of 4.42 dBi) is achieved at the lower band, whereas the higher band exhibits high-gain end-fire radiation with peak gain of 7.46 dBi. The proposed design concepts are validated by Ansys HFSS simulations as well as measurements carried out on fabricated array prototypes.
