The proposed antenna has a simple geometry using two substrates and does not require any additional cavity or parasitic elements. The designed and simulated antenna has an impedance bandwidth of more than 75%, a 3 dB axial ratio bandwidth of 67% and a peak gain of 12.4 dBic, with less than 3 dB gain variation across the entire axial ratio bandwidth. The antenna provides a good combination of simple and compact geometry, wide bandwidth, good gain and stable radiation patterns when compared to previously published research. Simulated as well as measured results are presented for a protype antenna array.en© 2025 The Author(s).
