چکیده
This paper proposes a dual-polarized filtering antenna with extracted-pole unit (EPU) using LTCC substrate. The EPU realizes the high skirt characteristic of bandpass filter transmission zeros (TZs) located near passband without cross coupling. is designed and fabricated in 28 GHz band for 5G Band-n257 (26.5-29.5 GHz). measured S11 less than -10.6 dB Band-n257, isolation between two ports dual polarization greater 20.0 dB. peak gain 4.0 dBi at 28.8 larger 2.5 Band-n257. frequency characteristics shows out band, which are good agreement electromagnetic (EM)-simulated results.

Compact filtering monopole patch antenna with dual-band rejection
In this paper, a compact ultra-wideband patch antenna with dual-band rejection is proposed. The proposed antenna filters 3.3-3.8 GHz WiMAX and 5.15-5.85 GHz WLAN by respectively rejecting these bands through a C-shaped slit and a λg/4 resonator. The λg/4 resonator is positioned as a pair, centered around the microstrip line, and a C-type slit is inserted into an elliptical patch. The impedance ...

A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...

Abstract—A novel compact printed antenna for dual band applications is presented. The antenna consists of two monopole elements and operates within the ISM 2.4 GHz and 5.2/5.8GHz frequency bands. The proposed antenna provides a bandwidth of 403 MHz (2.184 GHz–2.587GHz) in the lower frequency band and 4004 MHz (3.880 GHz–7.884 GHz) in the upper frequency band, respectively. Thus, it can cover mu...
