“…The HHPBW can also be broadened by reducing the widths of the radiating patch and ground plane of the microstrip antenna. This method and the differential-feed scheme are often simultaneously employed to design an antenna array with broad HHPBW and low XPL [10]- [12]. The HHPBWs in [10], [11], and [12] are 90°, 103°, and 120°, respectively, and all of their XPLs are below -20 dB.…”

Although the HHPBW can be further improved to 152° as a suspended patch antenna uses an inverted-V ground plane [13], the bulky antenna structure is unsuitable for practical array designs.…”

A design for wideband planar arrays with broad beamwidth and low cross polarization is described. The single element of the array is composed of a coaxial-cable-fed slot antenna, a shorting pin, and a planar reflector. For the single antenna, the effects of the key parameters on H-plane beamwidth and cross polarization are respectively studied. An optimum design is given, and both of its measured and simulated results prove that the single antenna has the characteristics of wide beamwidth and low cross polarization within an operating bandwidth of about 50 %. Based on the optimum design, a 1× 4 linear array is developed and constructed. Experimental results demonstrate that the array operating in the range from 1.7 to 2.7 GHz has a return loss of less than 13dB, a cross polarization level of smaller than -20 dB, and a half-power beamwidth of 100°±10° in the H-plane.

A wideband wide-coverage H-plane horn array with vertical polarization is proposed. Due to its light weight and low profile, the designed array is suitable for applications in spectrum monitoring systems on moving platforms. The switched-beam symmetrical array consists of four identical short H-plane horns. Pattern deterioration occurring in high frequency range is solved by inserting two pins in each horn. The measured impedance bandwidth is almost 100% for VSWR<2 owing to its fed structure with a thick-cylinder-loaded probe. The measured azimuth-plane beamwidth is about 90° over the entire frequency range from 860 MHz to 2500 MHz. Moreover, the measured results with the corresponding simulated ones are presented and discussed in this paper.Index Terms-H-plane horn, spectrum monitoring system, vehicular application, wide-band, wide-coverage. 0018-9545 (c)

This paper presents a novel design of low-profile circular array of H-plane horn antenna whose radiating aperture is on the side surface of a short solenoid. The designed antenna operates from 835MHz to 2436MHz and exhibits good radiation patterns and gain over the entire operating frequency band. Simulated results are provided to verify the design concept. This proposed antenna is potentially very useful for spectrum monitoring systems mounted a moving platform.Index Terms -Circular array, H-plane horn antenna, wideband antenna.
