Current article discusses the usefulness of Okumura-Hata model in urban areas for 2G and 3G communication systems. At some places, applicability of the model is observed and extended to a lower distance from the tower than the specified minimum dista

A simple singly fed dual band circularly polarized (CP) elliptical DRA is proposed at 2 and 3.5GHz. The antenna has been fabricated and was studied theoretically and experimentally giving close results. The measured axial ratio bandwidths for the two

A wideband, singly fed, circularly polarized, elliptical dielectric resonator antenna has been designed using a conformal open loop antenna in conjunction with a concentric parasitic open loop. A wideband 3dB axial ratio has been achieved over a band

Two circularly polarized open loop antennas, backed by square patch AMC ground planes and operating at the GPS Li band are presented. The first one is fed by a co-planar waveguide (CPW) and the second one is fed by a vertical probe. The CPW antenna h

A circularly polarized elliptical dielectric resonator antenna (EDRA) has been studied theoretically and experimentally when a single conformal strip is employed for excitation. The antenna has been analyzed using a rigorous moment method model in co
