N2 - This paper presents a new type of continuous transverse stub (CTS) antenna array with a novel linear source generator (LSG). The conventional multi-layer parallel-plate waveguide (PPW) feed and pillbox structure are eliminated and replaced with a more compact partially-corporate feed network. This helps to achieve a lower profile (or reduction of antenna layers) and high performance of broadband and high efficiency. For validation, two prototypes are demonstrated – one based on hollow waveguides operating at 34 – 41 GHz (Array-I) and the other based on substrate integrated waveguides (SIWs) operating at 24.5 – 29.5 GHz (Array-II). Both arrays contain eight radiation slots, fed from a single-layer PPW junction. The required quasi-TEM wave excitations are achieved by using the novel LSG of a jagged cavity structure. Detailed design methodology and analyses are provided in the paper. Measurements show that antenna efficiencies of over 83% and 82% with the peak gains of better than 27.6 dBi and 20.6 dBi are achieved for Array-I and II, respectively. These low-profile CTS designs are well suited for current and emerging millimeter-wave applications such as 5G and point-to-point communications.
